Foreword

This DICOM Standard was developed according to the procedures of the DICOM Standards Committee.

The DICOM Standard is structured as a multi-part document using the guidelines established in [ISO/IEC Directives, Part 2].

1 Scope and Field of Application

This Part of the DICOM Standard specifies application specific subsets of the DICOM Standard to which an implementation may claim conformance. Such a conformance statement applies to the interoperable interchange of medical images and related information on storage media for specific clinical uses. It follows the framework, defined in PS3.10, for the interchange of various types of information on storage media.

This Part is related to other parts of the DICOM Standard in that:

PS3.2, Conformance, specifies the general rules for assuring interoperability, which are applied for media interchange through the Application Profiles of this Part
PS3.3, Information Object Definitions, specifies a number of Information Object Definitions (e.g., various types of images) that may be used in conjunction with this Part. It also defines a medical Directory structure to facilitate access to the objects stored on media
PS3.4, Service Class Specifications, specifies the Media Storage Service Class upon which Application Profiles are built
PS3.5, Data Structure and Encoding, addresses the encoding rules necessary to construct a Data Set that is encapsulated in a file as specified in PS3.10
PS3.6, Data Dictionary, contains an index by Tag of all Data Elements related to the Attributes of Information Objects defined in PS3.3. This index includes the Value Representation and Value Multiplicity for each Data Element
PS3.10, Media Storage and File Formats for Media Interchange, standardizes the overall open Storage Media architecture used by this Part, including the definition of a generic File Format, a Basic File Service and a Directory concept
PS3.12, Media Formats and Physical Media, defines a number of standard Physical Media and corresponding Media Formats. These Media Formats and Physical Media selections are referenced by one or more of the Application Profiles of this Part. PS3.12 is intended to be extended as the technologies related to Physical Medium evolve
PS3.15, Security Profiles defines a number of profiles for use with Secure DICOM Media Storage Application Profiles. The Media Storage Security Profiles specify the cryptographic techniques to be used for each Secure DICOM File in a Secure Media Storage Application Profile.

6 Purpose of An Application Profile

An Application Profile is a mechanism for selecting an appropriate set of choices from the parts of DICOM for the support of a particular media interchange application. Application Profiles for commonly used interchange scenarios, such as inter-institutional exchange of X-Ray cardiac angiographic examinations, or printing ultrasound studies from recordable media, are meant to use the flexibility offered by DICOM without resulting in so many media and format choices that interchange is compromised.

Media interchange applications claim conformance to one or more Media Storage Application Profiles. Two implementations that conform to identical Application Profiles and support complementary File-set roles (e.g., an FSC interchanging media with an FSR) are able to exchange SOP Instances (pieces of DICOM information) on recorded media within the context of those Application Profiles.

A DICOM Application Profile specifies:

which SOP Classes and options must be supported, including any required extensions, specializations, or privatizations
for each SOP Class, which Transfer Syntaxes may be used
what information should be included in the Basic Directory IOD
which Media Storage Service Class options may be utilized
which roles an application may take: File-set Creator, File-set Reader, and/or File-set Updater
which physical media and corresponding media formats must be supported
whether or not the DICOM Files in the File-set shall be Secure DICOM Files
which Media Storage Security Profile must be used for the creation of Secure DICOM Files

and any additional conformance requirements.

The result of making the necessary choices means that the Application Profile can be thought of as a vertical path through the various parts of DICOM that begins with choices of information to be exchanged and ends at the physical medium. Figure 6-1 shows the relationship between the concepts used in an Application Profile and the parts of DICOM.

Figure 6-1. Relationship Between an Application Profile and Parts of DICOM

An Application Profile is organized into the following major parts:

The name of the Application Profile, or the list of Application Profiles grouped in a related class
A description of the clinical context of the Application Profile
The definition of the Media Storage Service Class with the device Roles for the Application Profile and associated options
Informative section describing the operational requirements of the Application Profile
Specification of the SOP Classes and associated IODs supported and the Transfer Syntaxes to be used
The selection of Media Format and Physical Media to be used
If the Directory Information Module is used, the description of the minimum subset of the Information Model required
Other parameters that need to be specified to ensure interoperable media interchange
Security parameters that select the cryptographic techniques to be used with Secure Media Storage Application Profiles

The structure of DICOM and the design of the Application Profile mechanism is such that extension to additional SOP Classes and new exchange media is straightforward.

7 Conformance Requirements

Implementations may claim conformance to one or more PS3.11 Application Profiles in a Conformance Statement as outlined in PS3.2.

Note

Additional specific conformance requirements for an Application Profile may be listed in the Application Profile definition.

8 Structure of Application Profile

Application Profiles specific to various clinical areas are defined in the Annexes to this Part. Each Annex defines an Application Profile Class related to a single area of medical practice, e.g., cardiology, or to a single functional context, e.g., image transfer to a printer system. Several specific Application Profiles may be defined in each Application Profile class, and an identification scheme is established to label each specific Application Profile.

An example of an Application Profile structure is provided in below. The section identifier "X" should be replaced by the identifier of the annex.

X.1 Class and Profile Identification

Section X.1 of the Application Profile defines the class and specific Application Profiles in that class.

This section assigns an identifier to each Application Profile of the form ttt-x...x-y...y, where "ttt" indicates the type of Application Profile, "x...x" is an abbreviation of a significant term for the clinical context and "y...y" is a significant term for a distinguishing feature of the specific Application Profile. The "ttt" type term shall be one of STD, AUG, or PRI, indicating whether the Application Profile is a Standard, Augmented, or Private Application Profile respectively (see PS3.2). Identifiers shall be written such that they may be encoded with LO (Long String) Value Representation (see PS3.5).

Note

Conformance Statements may use the earlier prefix of APL, which is equivalent to STD. This use is deprecated and may be retired in future editions of the Standard.

X.2 Clinical Context

Section X.2 of the Application Profile shall describe the clinical need for the interchange of medical images and related information on storage media, and its context of application. This section shall not require any specific functionality of the Application Entities exchanging information using media interchange beyond their capabilities in the roles of File-set Creator, File-set Reader, and File-set Updater.

Note

This Section does not, for example, place any graphical presentation or performance requirements on workstations that read DICOM interchange media. Such requirements are beyond the scope of a DICOM Media Storage Application Profile. The requirements that fall within the scope of an Application Profile are the specific functional storage media interchange capabilities associated with the defined roles.

X.2.1 Roles and Service Class Options

Section X.2.1 describes the Service Class Options used and the contextual application of the roles of File-set Creator, File-set Reader, and File-set Updater.

X.3 General Class Profile

Section X.3 defines characteristics of the Application Profile Class that are constant across all specific Application Profiles in the class.

X.3.1 SOP Classes and Transfer Syntaxes

Section X.3.1 lists the SOP Classes and Transfer Syntaxes common to all specific Application Profiles in the class, if any. This section specifies which SOP Classes are mandatory and optional for the roles of FSC, FSR, and FSU, including any required groupings or SOP options.

X.3.2 Physical Media and Media Formats

Section X.3.2 defines the physical media and corresponding media formats common to all specific Application Profiles in the class, if any.

This section also specifies any file service functionality beyond the DICOM File Service required by the clinical application to be supplied by the Media Format Layer.

X.3.3 Directory Information in DICOMDIR

Section X.3.3 specifies the type of Directory Records that shall be supported and any additional associated keys. It also defines any extensions to or specializations of the Basic Directory Information Object Definition, if any.

X.3.4 Other Parameters

Section X.3.4 is optional; if present, it should define any other parameters common to all specific Application Profiles in the class, which may need to be specified in order to ensure interoperable media interchange.

X.4 Specific Application Profiles

Section X.4 and following, each define the unique characteristics of a specific Application Profile. If there are any Application Profile specific changes to IODs, Transfer Syntax, DICOMDIR, or other general class requirements, they should be described for each Application Profile that specifies such changes.

X.3.5 Security Parameters

Section X.3.5 is optional; if absent, the Application Profile is unsecure and the Secure DICOM File Format shall not be used for any DICOM File in the File-set.

If present, this section defines the Media Storage Security Profile to be used for encapsulating allDICOM Files in the File-set, including the DICOM Directory. If this section is present, the Application Profile is called Secure Media Storage Application Profile.

A Basic Cardiac X-Ray Angiographic Application Profile (Normative)

A.1 Class and Profile Identification

This Annex defines an Application Profile Class for Basic Cardiac X-Ray Angiographic clinical applications.

The identifier for this class shall be STD-XABC. This annex is concerned only with cardiac angiography.

The specific Application Profile in this class is shown in the Table A.1-1.

Note

This table contains only a single Application Profile. It is expected that additional Application Profiles may be added to PS3.11.

Table A.1-1. Basic Cardiac XA Profile

Application Profile	Identifier	Description
Basic Cardiac X-Ray Angiographic Studies on CD-R Media	STD-XABC-CD	It handles single frame or multi-frame digital images up to 512x512x8 bits; biplane acquisitions are encoded as two single plane information objects.

A.2 Clinical Context

This Application Profile Class facilitates the interchange of primary digital X-Ray cine runs, typically acquired as part of cardiac catheterization procedures. Typical media interchanges would be from in-lab acquisition equipment to either a display workstation or to a data archive system, or between a display workstation and a data archive system (in both directions). This context is shown in Figure A.2-1.

Figure A.2-1. Basic Cardiac X-Ray Angiographic Clinical Context

The operational use of media interchange is potentially both intra-institutional and inter-institutional.

A.2.1 Roles and Service Class Options

This Application Profile Class uses the Media Storage Service Class defined in PS3.4.

The Application Entity shall support one or more of the roles of File-set Creator, File-set Reader, and File-set Updater, defined in PS3.10.

A.2.1.1 File Set Creator

The Application entity acting as a File-Set Creator generates a File Set under the STD-XABC Application Profile Class. Typical entities using this role would include X-Ray angiographic lab equipment, and archive systems that generate a patient record for transfer to another institution. File Set Creators shall be able to generate the Basic Directory SOP Class in the DICOMDIR File with all types of Directory Records related to the SOP Classes stored in the File-set.

FSC shall offer the ability to either finalize the disc at the completion of the most recent write session (no additional information can be subsequently added to the disc) or to allow multi-session (additional information may be subsequently added to the disk).

Note

A multiple volume (a logical volume that can cross multiple physical media) is not supported by this Application Profile Class. If a set of Files, e.g., a Study, cannot be written entirely on one CD-R, the FSC will create multiple independent DICOM File-sets such that each File-set can reside on a single CD-R media controlled by its individual DICOMDIR file. The user of the FSC can opt to use written labels on the discs to indicate that there is more than one disc for this set of files (e.g., a study).

A.2.1.2 File Set Reader

The role of File Set Reader is used by Application Entities that receive a transferred File Set. Typical entities using this role would include display workstations, and archive systems that receive a patient record transferred from another institution. File Set Readers shall be able to read all the SOP Classes defined for the specific Application Profile for which a Conformance Statement is made, using all the defined Transfer Syntaxes.

A.2.1.3 File Set Updater

The role of File Set Updater is used by Application Entities that receive a transferred File Set and update it by the addition of information. Typical entities using this role would include analytic workstations, which, for instance, may add to the File-set an information object containing a processed (e.g., edge-enhanced) image. Stations that update patient information objects would also use this role. File-set Updaters do not have to read the images. File-set Updaters shall be able to generate one or more of the SOP Instances defined for the specific Application Profile for which a conformance statement is made, and to read and update the DICOMDIR file.

FSU shall offer the ability to either finalize the disc at the completion of the most recent write session (no additional information can be subsequently added to the disc) or to allow multi-session (additional information may be subsequently added to the disk).

Note

If the disc has not been closed out, the File-set Updater shall be able to update information assuming there is enough space on the disc to write a new DICOMDIR file, the information, and the fundamental CD-R control structures. CD-R control structures are the structures that are inherent to the CD-R standards, see PS3.12.

A.3 STD-XABC-CD Basic Cardiac Profile

A.3.1 SOP Classes and Transfer Syntaxes

This Application Profile is based on the Media Storage Service Class (see PS3.4).

SOP Classes and corresponding Transfer Syntaxes supported by this Application Profile are specified in the Table A.3-1.

Optional

Note

This application profile does not allow the use of the X-Ray Angiographic Bi-Plane Image Object. Biplane acquisitions must therefore be transferred as two single plane SOP instances. A future Application Profile that permits X-Ray Angiographic Bi-Plane Image Object transfer is under development.
This Application Profile includes only the XA Image SOP Instances. It does not include Standalone Curve, Modality LUT, VOI LUT, or Overlay SOP Instances.

A.3.2 Physical Media and Media Formats

Basic Cardiac Application Profiles in the STD-XABC class require the 120 mm CD-R physical media with the ISO/IEC 9660 Media Format, as defined in PS3.12.

A.3.3 Directory Information in DICOMDIR

Conformant Application Entities shall include in the DICOMDIR File a Basic Directory IOD containing Directory Records at the Patient and subsidiary levels appropriate to the SOP Classes in the File-set.

Note

DICOMDIRs with no directory information are not allowed by this Application Profile.

A.3.3.1 Additional Keys

Table A.3-2 specifies the type of Directory Records that shall be supported and the additional associated keys. Refer to the Basic Directory IOD in PS3.3.

Table A.3-2. STD-XABC-CD Additional DICOMDIR Keys

Key Attribute	Tag	Directory Record Type	Type	Notes
Patient's Birth Date	(0010,0030)	PATIENT	2

Referenced Image Sequence	(0008,1140)	IMAGE	1C	Required if the SOP Instance referenced by the Directory Record has an Image Type (0008,0008) of BIPLANE A or BIPLANE B. May be present otherwise.
>Referenced SOP Class UID	(0008,1150)	IMAGE	1C	Required if Referenced Image Sequence (0008,1140) is present
>Referenced SOP Instance UID	(0008,1155)	IMAGE	1C	Required if Referenced Image Sequence (0008,1140) is present
>All other elements from Referenced Image Sequence (including Purpose of Reference Code Sequence and its content)		IMAGE	3

A.3.3.2 Icon Images

Directory Records of type IMAGE shall include Icon Images. The icon pixel data shall be supported with Bits Allocated (0028,0100) equal to 8 and Row (0028,0010) and Column (0028,0011) attribute values of 128.

Note

This icon size is larger than that recommended in PS3.10 because the 64x64 icon would not be clinically useful for identifying and selecting X-Ray angiographic images.
For multi-frame images, it is recommended that the icon image be derived from the frame identified in the Representative Frame Number attribute (0028,6010), if defined for the image SOP Instance. If the Representative Frame Number is not present, a frame approximately one-third of the way through the multi-frame image should be selected. The process to reduce a 512x512 image to a 128x128 image is beyond the scope of this Standard.

A.3.4 Other Parameters

This section defines other parameters common to all specific Application Profiles in the STD-XABC class that need to be specified in order to ensure interoperable media interchange.

A.3.4.1 Image Attribute Values

The attributes listed in Table A.3-3 used within the X-Ray Angiographic Image files shall take the values specified.

Table A.3-3. STD-XABC-CD- Required Image Attribute Values

Attribute	Tag	Value
Modality	(0008,0060)	XA
Rows	(0028,0010)	512 (see below)
Columns	(0028,0011)	512 (see below)
Bits Allocated	(0028,0100)	8
Bits Stored	(0028,0101)	8

When creating or updating a File-set, Rows or Columns shall not exceed a value of 512. When reading a File-set, an FSR or FSU shall accept a value of at least 512 for Rows or Columns.

Overlay data, if present, shall be encoded in Overlay Data (60XX,3000).

A.3.4.1.1 Attribute Value Precedence

Retired. See PS3.11 2004.

Note

The retired Detached Patient Management SOP Class was previously suggested to allow patient identification and demographic information to be updated without changing the composite Image IOD files. This usage is now retired.

B 1024 X-Ray Angiographic Application Profile (Normative)

B.1 Class and Profile Identification

This Annex defines a class of Application Profiles for 1024 X-Ray Angiographic clinical applications. The identifier for this class shall be STD-XA1K. It is the intent of these profiles to be backward compatible with the Basic Cardiac X-Ray Angiographic Application Profile (STD-XABC-CD) in Annex A.

The specific Application Profiles in this class are shown in the Table B.1-1.

Table B.1-1. 1024 X-Ray Angiographic Profiles

Application Profile	Identifier	Description
1024 X-Ray Angiographic Studies on CD-R Media	STD-XA1K-CD	It handles single frame or multi-frame X-Ray digital images up to 1024x1024x12 bits; biplane acquisitions are encoded as two single plane information objects. Secondary Capture images are supported.
1024 X-Ray Angiographic Studies on DVD Media	STD-XA1K-DVD	It handles single frame or multi-frame X-Ray digital images up to 1024x1024x12 bits; biplane acquisitions are encoded as two single plane information objects. Secondary Capture images are supported.

B.2 Clinical Context

This class of Application Profiles facilitates the interchange of primary digital X-Ray cine runs, typically acquired as part of angiographic procedures. Typical media interchanges would be from in-lab acquisition equipment to either a display workstation or to a data archive system, or between a display workstation and a data archive system (in both directions).

Additionally, images derived from or related to primary digital X-Ray cine runs, such as quantitative analysis images, reference images, multi-modality images and screen capture images, may be interchanged via this Profile.

The operational use of the media interchange is potentially both intra-institutional and inter-institutional.

Note

An FSC conforming to the Basic 512 Cardiac Angiographic Profile and General Purpose CD-R Profile supporting the SC Image Media Storage SOP Class could, if the restrictions in this profile were observed, create images that were readable by an FSR supporting the profile. Conversely, SC Images written by an FSC conforming to this profile, would be readable by an FSR conforming to the Basic 512 Cardiac Angiographic Profile and the General Purpose CD-R Profile supporting the SC Image Media Storage SOP Class.

B.2.1 Roles and Service Class Options

This Application Profile Class uses the Media Storage Service Class defined in PS3.4.

The Application Entity shall support one or more of the roles of File-set Creator, File-set Reader, and File-set Updater, defined in PS3.10.

B.2.1.1 File Set Creator

The Application entity acting as a File-Set Creator generates a File Set under the STD-XA1K Application Profile Class. Typical entities using this role would include X-Ray angiographic lab equipment, and archive systems that generate a patient record for transfer to another institution. File Set Creators shall be able to generate the Basic Directory SOP Class in the DICOMDIR File with all types of Directory Records related to the SOP Classes stored in the File-set.

An FSC shall offer the ability to either finalize the disc at the completion of the most recent write session (no additional information can be subsequently added to the disc) or to allow multi-session (additional information may be subsequently added to the disc). An FSC may allow packet-writing if supported by the media and file system specified in the profile.

Note

A multiple volume (a logical volume that can cross multiple physical media) is not supported by this Application Profile Class. If a set of Files, e.g., a Study, cannot be written entirely on one piece of media, the FSC will create multiple independent DICOM File-sets such that each File-set can reside on a single piece of media controlled by its individual DICOMDIR file. The user of the FSC can opt to use written labels on the discs to reflect that there is more than one disc for this set of files (e.g., a Study).

B.2.1.2 File Set Reader

The role of File Set Reader shall be used by Application Entities that receive a transferred File Set. Typical entities using this role would include display workstations, and archive systems that receive a patient record transferred from another institution. File Set Readers shall be able to read all the defined SOP Instances defined for the specific Application Profiles to which a conformance claim is made, using all the defined Transfer Syntaxes.

B.2.1.3 File Set Updater

The role of File Set Updater shall be used by Application Entities that receive a transferred File Set and update it by the addition of processed information. Typical entities using this role would include analytic workstations, which for instance may add to the File Set an information object containing a processed (e.g., edge-enhanced) image frame. Stations that update patient information objects would also use this role. File-set Updaters shall be able to read and update the DICOMDIR file. File-set Updaters do not have to read the image information object. File-set Updaters shall be able to generate one or more of the SOP Instances defined for the specific Application Profiles to which a conformance claim is made, and to read and update the DICOMDIR file.

An FSU shall offer the ability to either finalize the disc at the completion of the most recent write session (no additional information can be subsequently added to the disc) or to allow multi-session (additional information may be subsequently added to the disc).

Note

If the disc has not been finalized, the File-set Updater will be able to update information assuming there is enough space on the disc to write a new DICOMDIR file, the information, and the fundamental volume control structures. Volume control structures are the structures that are inherent to the standards of the physical volume; see PS3.12

The FSU role is not defined for the STD-XA1K-DVD profile.

Note

The FSU requirement is not defined for STD-XA1K-DVD profile.
The Standalone Overlay, Standalone Curve and Detached Patient management SOP Classes were formerly defined in these profiles, but have been retired. The Grayscale Softcopy Presentation State Storage SOP Class has been added as the preferred mechanism for conveying annotations.

B.3.2 Physical Media and Media Formats

The 1024 X-Ray Angiographic Application CD-R Profile STD-XA1K-CD requires the 120mm CD-R physical media with the ISO/IEC 9660 Media Format, as defined in PS3.12.

The 1024 X-Ray Angiographic Application DVD profile STD-XA1K-DVD requires any of the 120 mm DVD media other than DVD-RAM as defined in PS3.12.

B.3.3 Directory Information in DICOMDIR

Conformant Application Entities shall include in the DICOMDIR File a Basic Directory IOD containing Directory Records at the Patient and subsidiary levels appropriate to the SOP Classes in the File-set.

Note

DICOMDIRs with no directory information are not allowed by this Application Profile.

B.3.3.1 Additional Keys

Table B.3-2 specifies the type of Directory Records that shall be supported and the additional associated keys. Refer to the Basic Directory IOD in PS3.3.

Table B.3-2. STD-XA1K Additional DICOMDIR Keys

Key Attribute	Tag	Directory Record Type	Type	Notes
Patient's Birth Date	(0010,0030)	PATIENT	2
Patient's Sex	(0010,0040)	PATIENT	2

B.3.3.2 Icon Images

Directory Records of type IMAGE shall include Icon Images. The icon pixel data shall be Bits Allocated and Bits Stored (0028,0101) attribute values of 8 with Row (0028,0010) and Column (0028,0011) attribute values of 128 and Photometric Interpretation (0028,0004) attribute value of MONOCHROME2.

Note

It is recommended that the Icon Images be encoding using VR OB encoding. The use of OW, allowed by the STD-XABC-CD Basic Cardiac profile defined in Annex A, is deprecated, and may be retired in future editions of the Standard.
This icon size is larger than that recommended in PS3.10 because the 64x64 icon would not be clinically useful for identifying and selecting X-Ray angiographic images.
For multi-frame images, it is recommended that the icon image be derived from the frame identified in the Representative Frame Number attribute (0028,6010), if defined for the image SOP Instance. If the Representative Frame Number is not present, a frame approximately one-third of the way through the multi-frame image should be selected. The process to reduce any image to a 128x128 image is beyond the scope of this Standard.

B.3.4 Other Parameters

This section defines other parameters common to all specific Application Profiles in the STD-XA1K class that need to be specified in order to ensure interoperable media interchange.

C Ultrasound Application Profile (Normative)

C.1 Class and Profile Identification

This Annex defines Application Profiles for Ultrasound Media Storage applications. Each Application Profile has a unique identifier used for conformance claims. Due to the variety of clinical applications of storage media in Ultrasound, a family of application profiles are described in this section to best tailor an application choice to the specific needs of the user. The identifier used to describe each profile is broken down into three parts: a prefix, mid-section, and suffix. The prefix describes the overall Application Profile Class and is common for all ultrasound application profiles. The mid section describes the specific clinical application of the profile. The suffix is used to describe the actual media choice the profile will use.

The prefix for this class of application profiles is identified with the STD-US identifier.

Note

Conformance Statements may use the earlier prefix of APL that is equivalent to STD. This use is deprecated and may be retired in future editions of the Standard.

The midsection is broken down into three subclasses that describe the clinical use of the data. These subclasses are: Image Display (ID identifier), Spatial Calibration (SC identifier), and Combined Calibration (CC identifier). All three subclasses can be applied to either single frames (SF) images or single and multi-frames (MF) images. The SC subclass enhances the ID class by adding the requirement for region specific spatial calibration data with each IOD. The CC subclass enhances the SC subclass by requiring region specific pixel component calibration.

The suffix, xxxx, is used to describe the actual media choice used for the conformance claim. Any of the above mentioned classes can be stored onto one of eight pieces of media described in the Table C.3-3.

The specific Application Profiles are shown in the following table.

Table C.1-1. Ultrasound Application Profile identifiers

Application Profile	Single Frame	Single & Multi-Frame
Image Display	STD-US-ID-SF-xxxx	STD-US-ID-MF-xxxx
Spatial Calibration	STD-US-SC-SF-xxxx	STD-US-SC-MF-xxxx
Combined Calibration	STD-US-CC-SF-xxxx	STD-US-CC-MF-xxxx

The ID Application Profile Classes are intended to be used for the transfer of ultrasound images for display purposes.

The SC Application Profile Classes are intended to be used for the transfer of ultrasound images with spatial calibration data for quantitative purposes (see Section C.4).

The CC Application Profile Classes are intended to be used for the transfer of ultrasound images with spatial and pixel component calibration data for more advanced quantitative purposes (see Section C.5).

C.2 Clinical Context

These classes of Application Profiles facilitate the interchange of ultrasound data on media. Typical interchanges would be between ultrasound systems, between an ultrasound system and a display workstation, between display workstations, or between an ultrasound system and a data archive. This context is shown in Figure C.2-1.

Figure C.2-1. Ultrasound Clinical Context

The operational use of the media transfer is potentially both intra-institutional and inter-institutional.

C.2.1 Roles

C.2.1.1 File Set Creator

The role of File Set Creator shall be used by Application Entities that generate a File Set under the STD-US class of Application Profiles. Typical entities using this role would include ultrasound imaging equipment, workstations, and archive systems that generate a patient record for transfer. File Set Creators shall be able to generate the DICOMDIR directory file, single and/or multi frame Ultrasound Information Object files, and depending on the subclass, region specific calibration in the defined Transfer Syntaxes.

An FSC shall offer the ability to either finalize the disc at the completion of the most recent write session (no additional information can be subsequently added to the disc) or to allow multi-session (additional information may be subsequently added to the disc) or to allow packet-writing, if supported by the media and file system specified in the profile.

C.2.1.2 File Set Reader

The role of File Set Reader shall be used by Application Entities that receive a transferred File Set. Typical entities using this role would include ultrasound systems, display workstations, and archive systems that receive a patient record from a piece of media. File Set Readers shall be able to read the DICOMDIR directory file and all Information Objects defined for the specific Application Profiles, using the defined Transfer Syntaxes.

C.2.1.3 File Set Updater

The role of File Set Updater shall be used by Application Entities that receive a transferred File Set and updates it by the addition or deletion of objects to the media. Typical entities using this role would include ultrasound systems adding new patient records to the media and workstations that may add an information object containing a processed or modified image.

An FSU shall offer the ability to either finalize the disc at the completion of the most recent write session (no additional information can be subsequently added to the disc) or to allow multi-session (additional information may be subsequently added to the disc) or to allow packet-writing, if supported by the media and file system specified in the profile.

The FSU role is not defined for the STD-US-xx-xx-DVD profiles (i.e., for DVD media that is not DVD-RAM).

C.3 General Class Profile

C.3.1 Abstract and Transfer Syntaxes

Application Profiles in this class, STD-US, shall support the appropriate Information Object Definitions (IOD) and Transfer Syntaxes for the Media Storage SOP Class in the following table. In the role of FS-Updater or FS-Creator the application can choose one of the three possible transfer Syntaxes to create an IOD.

Note

Media Classes FLOP, MOD128, MOD230, MOD540, MOD640, MOD650, MOD12 AND MOD23 were previously defined but have been retired. See PS3.11 2004.

C.3.3 DICOMDIR

The Directory shall include Directory Records of PATIENT, STUDY, SERIES, IMAGE corresponding to the information object files in the File Set. All DICOM files in the File Set incorporating SOP Instances (Information Objects) defined for the specific Application Profile shall be referenced by Directory Records. At the image level each file contains a single ultrasound image object or a single ultrasound multi-frame image object as defined in PS3.3 of the Standard.

Note

For all media selected in this Application Profile Class, STD-US, the following applies as defined in PS3.12.

All implementations should include the DICOM Media Storage Directory in the DICOMDIR file. There should only be one DICOMDIR file on a single media. The DICOMDIR file should be found in the root directory of the media. For the case of double-sided MOD media, there shall be a DICOMDIR on each side of the media.

On a single media the patient ID key at the patient level shall be unique for each patient directory record.

C.3.3.1 Additional Keys

File Set Creators and Updaters are only required to generate mandatory elements specified in PS3.10. At each directory record level any additional data elements can be added as keys, but is not required by File Set Readers to be able to use them as keys.

C.3.3.2 File Component IDs

Note

File Component IDs should be created using a random number filename to minimize File Component ID collisions as described in PS3.12. The FS-Updater should check the existence of a Component ID prior to creating that ID. Should an ID collision occur, the FS-Updater should try another ID.

C.4 Spatial Calibration (SC) Class Requirements

All implementations conforming to the Application Profile Class SC shall include the US Region Calibration Module with the exception of pixel component organization data element (0018,6044) and other data elements that are conditional on that data element.

C.5 Combined Calibration (CC) Class Requirements

All implementations conforming to the Application Profile Class CC shall include the US Region Calibration Module including the pixel component organization data element (0018,6044) and other data elements that are conditional on that data element.

D General Purpose CD-R, DVD and BD Interchange Profiles (Normative)

D.1 Profile Identification

This Annex defines an Application Profile Class potentially inclusive of all defined Media Storage SOP Classes. This class is intended to be used for the interchange of Composite SOP Instances via CD-R, DVD-RAM and BD media for general purpose applications. Objects from multiple modalities may be included on the same media.

A detailed list of the Media Storage SOP Classes that may be supported is defined in PS3.4.

Table D.1-1. STD-GEN Profile

Application Profile	Identifier	Description
General Purpose CD-R Interchange	STD-GEN-CD	Handles interchange of Composite SOP Instances such as Images, Structured Reports, Presentation States and Waveforms.
General Purpose Interchange on DVD-RAM Media	STD-GEN-DVD-RAM	Handles interchange of Composite SOP Instances such as Images, Structured Reports, Presentation States and Waveforms.
General Purpose Secure CD-R Interchange	STD-GEN-SEC-CD	Handles interchange of Composite SOP Instances such as Images, Structured Reports, Presentation States and Waveforms. Offers confidentiality, integrity and, depending on the File-set creator's choice, data origin authentication.
General Purpose Secure Interchange on DVD-RAM Media	STD-GEN-SEC-DVD-RAM	Handles interchange of Composite SOP Instances such as Images, Structured Reports, Presentation States and Waveforms. Offers confidentiality, integrity and, depending on the File-set creator's choice, data origin authentication.
General Purpose Interchange on BD Media	STD-GEN-BD	Handles Interchange of Composite SOP Instances such as Images, Structured Reports, Presentation States and Waveforms.
General Purpose Secure Interchange on BD Media	STD-GEN-SEC-BD	Handles Interchange of Composite SOP Instances such as Images, Structured Reports, Presentation States and Waveforms. Offers confidentiality, integrity and, depending on the File-set creator's choice, data origin authentication.

The identifier for this General Purpose Image Exchange profile class shall be STD-GEN.

Equipment claiming conformance to this Application Profile shall list the subset of Media Storage SOP Classes that it supports in its Conformance Statement.

Note

Since it is not required to support all Media Storage Classes the user should carefully consider the subset of supported Media Storage SOP Classes in the Conformance Statements of such equipment to establish effective object interchange.

D.2 Clinical Context

This Application Profile facilitates the interchange of images and related data on CD-R, DVD-RAM and BD media. Typical interchange would be between acquisition devices, archives and workstations.

This Application Profile facilitates the creation of a multi-modality medium for image interchange, useful for clinical, patient record, teaching and research applications, within and between institutions.

This profile is intended only for general purpose applications. It is not intended as a replacement for specific Application Profiles that may be defined for a particular clinical context. The latter may support compression Transfer Syntaxes, limitations on the form and content of SOP Class instances, and specific media choices that preclude the use of the General Purpose Interchange Profile.

Note

The creation of a CD, DVD-RAM or BD is considerably more complex than the reading thereof. Therefore the clinical context for this Application profile is likely to be asymmetric, with a sophisticated File Set Creator and relatively simple File Set Readers.

D.2.1 Roles and Service Class Options

This Application Profile uses the Media Storage Service Class defined in PS3.4.

The Application Entity shall support one or more of the roles of File Set Creator (FSC), File Set Reader (FSR), and File Set Updater (FSU), defined in PS3.10.

D.2.1.1 File Set Creator

The role of File Set Creator shall be used by Application Entities that generate a File Set under this Image Interchange Class of Application Profiles.

File Set Creators shall be able to generate the Basic Directory SOP Class in the DICOMDIR file with all the subsidiary Directory Records related to the Image SOP Classes stored in the File Set. The Application Entity acting as a File Set Creator generates a File Set under a STD-GEN Application Profile.

FSC shall offer the ability to either finalize the physical volume at the completion of the most recent write session (no additional information can be subsequently added to the volume) or to allow multi-session (additional information may be subsequently added to the volume) or to allow packet-writing, if supported by the media and file system specified in the profile.

Note

A multiple volume (i.e., a logical volume that can cross multiple physical media) is not supported by this class of Application profile. If a set of Files, e.g., a Study, cannot be written entirely on one physical volume (side of one piece of media), the FSC will create multiple independent DICOM File Sets such that each File Set can reside on a single physical volume (side of a single piece of media) controlled by its individual DICOMDIR file. The user of the FSC can opt to use written labels on the physical volumes to indicate that there is more than one physical volume for this set of files (e.g., a study).

D.2.1.2 File Set Reader

The role of File Set Reader shall be used by Application Entities that receive a transferred File Set under the Image Interchange Class of Application Profiles. Typical entities using this role would include image generating systems, display workstations, and archive systems that receive a patient record; e.g., transferred from another institution.

File Set Readers shall be able to read the DICOMDIR directory file and all the SOP Instance files defined for this Application Profile, for which a Conformance Statement is made, using the defined Transfer Syntax.

D.2.1.3 File Set Updater

The role of File Set Updater is used by Application Entities that receive a transferred File Set under the Image Exchange Class of Application Profiles and update it by the addition (or deletion) of images or information to (or from) the medium. Typical entities using this role would include image generating systems and workstations that process or modify images.

File Set Updaters shall be able to generate one or more of the SOP Instances defined for this Application Profile, for which a Conformance Statement is made, and to read and update the DICOMDIR file.

FSU shall offer the ability to either finalize the physical volume at the completion of the most recent write session (no additional information can be subsequently added to the volume) or to allow multi-session (additional information may be subsequently added to the volume) or to allow packet-writing. if supported by the media and file system specified in the profile.

Note

If the volume has not been finalized, the File Set Updater will be able to update information assuming there is enough space on the volume to write a new DICOMDIR file, the information, and the fundamental volume control structures. Volume control structures are the structures that are inherent to the standards of the physical volume, see PS3.12.

The STD-GEN-BD and STD-GEN-SEC-BD application profiles require any of the 120 mm BD media, as defined in PS3.12.

D.3.3 Directory Information in DICOMDIR

Conformant Application Entities shall include in the DICOMDIR File the Basic Directory IOD containing Directory Records at the Patient and the subsidiary Study and Series levels, appropriate to the SOP Classes in the File Set.

All DICOM files in the File Set incorporating SOP Instances defined for the specific Application Profile shall be referenced by Directory Records.

Note

DICOMDIRs with no directory information are not allowed by this Application Profile.

All implementations shall include the DICOM Media Storage Directory in the DICOMDIR file. There shall only be one DICOMDIR file per File Set. The DICOMDIR file shall be in the root directory of the medium. The Patient ID at the patient level shall be unique for each patient directory record in one File Set.

D.3.3.1 Additional Keys

File Set Creators and Updaters are required to generate the mandatory elements specified in PS3.3.

Table D.3-2 specifies the additional associated keys. At each directory record level other additional data elements can be added, but it is not required that File Set Readers be able to use them as keys. Refer to the Basic Directory IOD in PS3.3.

The retired Detached Patient Management SOP Class was previously suggested to allow patient identification and demographic information to be updated without changing the composite Image IOD files. This usage is now retired.

D.3.4 Other Parameters

Not applicable.

D.3.5 Security Parameters

The STD-GEN-SEC-CD, STD-GEN-SEC-DVD-RAM and STD-GEN-SEC-BD application profiles require that all DICOM Files in the File-set including the DICOMDIR be Secure DICOM Files encapsulated in accordance with the requirements of the Basic DICOM Media Security Profile as defined in PS3.15.

Note

These Application Profiles do not place any consistency restrictions on the use of the Basic DICOM Media Security Profile with different DICOM Files of one File-set. For example, readers should not assume that all Files in the File-set can be decoded by the same set of recipients. Readers should also not assume that all secure Files use the same approach (hash key or digital signature) to ensure Integrity or carry the same originators' signatures.

E CT and MR Image Application Profiles (Normative)

E.1 Profile Identification

This Annex defines Application Profiles for Computed Tomography and Magnetic Resonance Imaging interchange and storage on high capacity rewritable magneto-optical disks (MOD) and CD-R and DVD-RAM and other DVD media uncompressed and with lossless compression.

Table E.1-1. STD-CTMR Profiles

Application Profile	Identifier	Description
CT/MR Studies on 4.1GB MOD	STD-CTMR-MOD41	Handles single frame 8, 12 or 16 bit grayscale and 8 bit palette color, uncompressed and lossless compressed images.
CT/MR Studies on CD-R	STD-CTMR-CD	Handles single frame 8, 12 or 16 bit grayscale and 8 bit palette color, uncompressed and lossless compressed images.
CT/MR Studies on DVD-RAM Media	STD-CTMR-DVD-RAM	Handles single frame 8, 12 or 16 bit grayscale and 8 bit palette color, uncompressed and lossless compressed images.
CT/MR Studies on DVD Media	STD-CTMR-DVD	Handles single frame 8, 12 or 16 bit grayscale and 8 bit palette color, uncompressed and lossless compressed images.

Note

Media Profiles STD-CTMR-MOD650, STD-CTMR-MOD12 and STD-CTMR-MOD23 were previously defined but have been retired. See PS3.11 2004.

E.2 Clinical Context

These Application Profiles facilitate the interchange and storage of primary CT and MR images as well as related Secondary Capture Images with certain defined attributes, including grayscale and palette color images. CT, MR and SC images may co-exist within the same File-set.

Typical interchanges would be between acquisition devices, archives and workstations, within and between institutions.

E.2.1 Roles and Service Class Options

These Application Profiles uses the Media Storage Service Class defined in PS3.4.

The Application Entity shall support one or more of the roles of File-set Creator, File-set Reader, and File-set Updater, defined in PS3.10.

E.2.1.1 File Set Creator

The Application entity acting as a File-Set Creator generates a File Set under a STD-CTMR Application Profile. Typical entities using this role would include CT or MR equipment, and archive systems that generate a patient record for transfer to another institution. File Set Creators shall be able to generate the Basic Directory SOP Class in the DICOMDIR File with all types of Directory Records related to the SOP Classes stored in the File-set.

An FSC shall offer the ability to either finalize the disc at the completion of the most recent write session (no additional information can be subsequently added to the disc) or to allow multi-session (additional information may be subsequently added to the disc) or to allow packet-writing, if supported by the media and file system specified in the profile.

Note

A multiple volume (a logical volume that can cross multiple physical media) is not supported by this class of Application profile. If a set of Files, e.g., a Study, cannot be written entirely on one physical volume, the FSC will create multiple independent DICOM File-sets such that each File-set can reside on a single physical volume controlled by its individual DICOMDIR file. The user of the FSC can opt to use written labels on the physical volumes to indicate that there is more than one physical volume for this set of files (e.g., a study).

E.2.1.2 File Set Reader

The role of File Set Reader is used by Application Entities that receive a transferred File Set. Typical entities using this role would include display workstations, and archive systems that receive a patient record transferred from another institution. File Set Readers shall be able to read all the SOP Classes defined for the specific Application Profile for which a Conformance Statement is made, using all the defined Transfer Syntaxes.

E.2.1.3 File Set Updater

The role of File Set Updater is used by Application Entities that receive a transferred File Set and update it by the addition of information. Typical entities using this role would include analytic workstations, which, for instance, may add to the File-set an information object containing a processed image. Stations that update patient information objects would also use this role. File-set Updaters do not have to read the images. File-set Updaters shall be able to generate one or more of the SOP Instances defined for the specific Application Profile for which a conformance statement is made, and to read and update the DICOMDIR file.

An FSU shall offer the ability to either finalize the disc at the completion of the most recent write session (no additional information can be subsequently added to the disc) or to allow multi-session (additional information may be subsequently added to the disc) or to allow packet-writing if supported by the media and file system specified in the profile.

Note

If the volume has not been finalized, the File Set Updater will be able to update information assuming there is enough space on the volume to write a new DICOMDIR file, the information, and the fundamental volume control structures. Volume control structures are the structures that are inherent to the standards of the physical volume, see PS3.12.

The FSU role is not defined for the STD-CTMR-DVD profile.

The STD-CTMR-DVD application profile requires any of the 120 mm DVD media other than DVD-RAM, as defined in PS3.12.

E.3.3 Directory Information in DICOMDIR

Conformant Application Entities shall include in the DICOMDIR File a Basic Directory IOD containing Directory Records at the Patient and subsidiary levels appropriate to the SOP Classes in the File-set. All DICOM files in the File-set incorporating SOP Instances defined for the specific Application Profile shall be referenced by Directory Records.

Note

DICOMDIRs with no directory information are not allowed by this Application Profile.

E.3.3.1 Additional Keys

File Set Creators and Updaters are required to generate the mandatory elements specified in Annex F “Basic Directory IOD (Normative)” in PS3.3.

E.3.3.2 Localizer Related Attributes

Directory Records of type IMAGE shall include the mandatory attributes from the Frame of Reference and Image Plane modules, if present in the composite image object, as specified in PS3.3 and included in Table E.3-2, in order to allow the image to be referenced to a localizer image or other orthogonal image. The Rows (0028,0010) and Columns (0028,0011) attributes are required in order to facilitate annotation of such a localizer.

Note

The Frame of Reference module is specified in PS3.3 as mandatory for the CT and MR composite information objects, but not for Secondary Capture objects.

E.3.3.3 Icon Images

Directory Records of type SERIES or IMAGE may include Icon Images. The icon pixel data shall be as specified in PS3.3 Icon Image Key Definition, and restricted such that Photometric Interpretation (0028,0004) shall be MONOCHROME2 or PALETTE COLOR, Bits Allocated (0028,0100) and Bits Stored (0028,0101) shall be equal to 8, and Rows (0028,0010) and Columns (0028,0011) shall be equal to 64.

E.3.4 Other Parameters

Note

The Basic Directory Information Object definition in PS3.3 defines the following attributes as Type 1 or 2: for PATIENT directory records: (0010,0010) Patient's Name; for STUDY directory records: (0008,0050) Accession Number, (0008,0020) Study Date, (0008,1030) Study Description; for SERIES directory records: (0008,0060) Modality. Hence these are not redefined here.
The Basic Directory Information Object definition in PS3.3 allows for the optional inclusion of Icon Images at the IMAGE or SERIES level. These remain optional for this profile, and the choice of whether or not to include Icon Images for every image or series, or in a more selective manner, is left up to the implementer. E.3.3.3 describes restrictions that apply to Icon Images that are included in this profile.

E.3.4.1 Image Attribute Values

The attributes listed in Table E.3-3 used within CT Image files, those listed in Table E.3-4 used within MR Image files, those listed in Table E.3-5 used within grayscale SC Image files, and those listed in Table E.3-6 used within color SC Image files, shall take the values specified, which are more specific than, but must be consistent with, those specified in the definition of the CT, MR and SC Image Information Object Definitions in PS3.3.

F Waveform Diskette Interchange Profile (Normative)

Retired. See PS3.11 2004.

G General Purpose MIME Interchange Profile (Normative)

G.1 Profile Identification

This Annex defines an Application Profile Class including all defined Media Storage SOP Classes. This class is intended to be used for the interchange of Composite SOP Instances via e-mail for general purpose applications.

Note

This Media Storage Application Profile Class is not intended to replace the more robust DICOM Storage Service Class.

Objects from multiple modalities may be included on the same e-mail. A detailed list of the Media Storage SOP Classes that may be supported is defined in PS3.4.

Table G.1-1. STD-GEN-MIME Profile

Application Profile	Identifier	Description
General Purpose MIME Interchange	STD-GEN-MIME	Handles interchange of Composite SOP Instances by e-mail.

The identifier for this General Purpose MIME Interchange profile shall be STD-GEN-MIME.

Equipment claiming conformance to this Application Profile shall list the subset of Media Storage SOP Classes that it supports in its Conformance Statement.

Note

Since it is not required to support all Media Storage Classes the user should carefully consider the subset of supported Media Storage SOP Classes in the Conformance Statements of such equipment to establish effective object interchange.

G.2 Clinical Context

This Application Profile facilitates the interchange of images and related data through e-mail.

This profile is intended only for general purpose applications. It is not intended as a replacement for specific Application Profiles that may be defined for a particular clinical context.

Note

The present Application Profile does not include any specific mechanism regarding privacy. However it is highly recommended to use secure mechanisms (e.g., S/MIME) when using STD-GEN-MIME Application Profile over networks that are not otherwise secured.

G.2.1 Roles and Service Class Options

This Application Profile uses the Media Storage Service Class defined in PS3.4.

The Application Entity shall support one or two of the roles of File Set Creator (FSC) and File Set Reader (FSR), defined in PS3.10. Because the exchange of e-mail does not involve storage, the role of File Set Updater (FSU) is not specified.

G.2.1.1 File Set Creator

The role of File Set Creator may be used by Application Entities that generate a File Set under this Interchange Class of Application Profiles.

File Set Creators may be able to generate the Basic Directory SOP Class in the DICOMDIR file with all the subsidiary Directory Records related to the Image SOP Classes included in the File Set.

The Application Entity acting as a File Set Creator generates a File Set under the STD-GEN-MIME Application Profile.

Note

A multiple volume (i.e., a logical volume that can cross multiple media) is not supported by this class of Application profile. Because MIME is a virtual medium and since e-mail mechanisms include some way of fragmenting MIME parts to be sent through limited size e-mail, there are no needs for multiple volume.

G.2.1.2 File Set Reader

The role of File Set Reader shall be used by Application Entities that receive an exchanged File Set under the Image Interchange Class of Application Profiles.

File Set Readers may be able to read the DICOMDIR directory file and shall be able to read all the SOP Instance files defined for this Application Profile, using the Transfer Syntaxes specified in the Conformance Statement.

G.3 STD-GEN-MIME Profile

G.3.1 SOP Classes and Transfer Syntaxes

This Application Profile is based on the Media Storage Service Class (see PS3.4).

The SOP Classes and corresponding Transfer Syntax supported by this Application Profile are specified in the Table G.3-1. The supported Storage SOP Class(es) and Transfers Syntax(es) shall be listed in the Conformance Statement using a table of the same form.

G.3.2 Physical Medium and Medium Format

The STD-GEN-MIME application profile requires the DICOM MIME medium as defined in PS3.12.

G.3.3 Directory Information in DICOMDIR

If the DICOMDIR is included, conformant Application Entities shall include in it the Basic Directory IOD containing Directory Records at the Patient and the subsidiary Study and Series levels, appropriate to the SOP Classes in the File Set.

All DICOM files in the File Set incorporating SOP Instances defined for the specific Application Profile shall be referenced by Directory Records.

Note

DICOMDIRs with no directory information are not allowed by this Application Profile.
In the DICOMDIR each object may be referenced by a referenced file ID (e.g., 000/000) that contains multiple values corresponding to a path for physical system, since the MIME organization is flat. There is no requirement that this path will be used by the receiving application to create file hierarchy.

There may only be one DICOMDIR file per File Set. The Patient ID at the patient level shall be unique for each patient directory record in one File Set.

G.3.3.1 Additional Keys

No additional keys are specified.

H General Purpose DVD With Compression Interchange Profiles (Normative)

H.1 Profile Identification

This Annex defines an Application Profile Class potentially inclusive of all defined Media Storage SOP Classes. This class is intended to be used for the interchange of Composite SOP Instances via DVD media for general purpose applications. Objects from multiple modalities may be included on the same media. Images may be compressed with or without loss using either JPEG or JPEG 2000; all File Set Readers are required to support decompression of all of the compressed Transfer Syntaxes defined for each Profile.

A detailed list of the Media Storage SOP Classes that may be supported is defined in PS3.4.

Table H.1-1. STD-GEN-DVD and STD-GEN-SEC-DVD Profiles

Application Profile	Identifier	Description
General Purpose DVD Interchange with JPEG	STD-GEN-DVD-JPEG	Handles interchange of Composite SOP Instances such as Images, Structured Reports, Presentation States and Waveforms, either uncompressed or with lossless or lossy JPEG.
General Purpose DVD Interchange with JPEG 2000	STD-GEN-DVD-J2K	Handles interchange of Composite SOP Instances such as Images, Structured Reports, Presentation States and Waveforms, either uncompressed or with lossless or lossy JPEG 2000.
General Purpose Secure DVD Interchange with JPEG	STD-GEN-SEC-DVD-JPEG	Handles interchange of Composite SOP Instances such as Images, Structured Reports, Presentation States and Waveforms, either uncompressed or with lossless or lossy JPEG. Offers confidentiality, integrity and, depending on the File-set creator's choice, data origin authentication.
General Purpose Secure DVD Interchange with JPEG 2000	STD-GEN-SEC-DVD-J2K	Handles interchange of Composite SOP Instances such as Images, Structured Reports, Presentation States and Waveforms, either uncompressed or with lossless or lossy JPEG 2000. Offers confidentiality, integrity and, depending on the File-set creator's choice, data origin authentication.

Equipment claiming conformance to this Application Profile shall list the subset of Media Storage SOP Classes that it supports in its Conformance Statement.

Note

Since it is not required to support all Media Storage Classes the user should carefully consider the subset of supported Media Storage SOP Classes in the Conformance Statements of such equipment to establish effective object interchange.

H.2 Clinical Context

This Application Profile Class facilitates the interchange of images and related data on DVD media. Typical interchange would be between acquisition devices, archives and workstations.

This Application Profile Class facilitates the creation of a multi-modality medium for image interchange, useful for clinical, patient record, teaching and research applications, within and between institutions.

This profile is intended only for general purpose applications. It is not intended as a replacement for specific Application Profiles that may be defined for a particular clinical context.

Note

The creation of a DVD is considerably more complex than the reading thereof. Therefore the clinical context for this Application profile is likely to be asymmetric, with a sophisticated File Set Creator and relatively simple File Set Readers.

H.2.1 Roles and Service Class Options

This Application Profile Class uses the Media Storage Service Class defined in PS3.4.

The Application Entity shall support one or more of the roles of File Set Creator (FSC) or File Set Reader (FSR), defined in PS3.10. The File Set Updater (FSU) role is not defined.

H.2.1.1 File Set Creator

The role of File Set Creator shall be used by Application Entities that generate a File Set under this Image Interchange Class of Application Profiles.

File Set Creators shall be able to generate the Basic Directory SOP Class in the DICOMDIR file with all the subsidiary Directory Records related to the Image SOP Classes stored in the File Set. The Application Entity acting as a File Set Creator generates a File Set under a STD-GEN-DVD or STD-GEN-SEC-DVD Application Profile.

FSC shall offer the ability to either finalize the physical volume at the completion of the most recent write session (no additional information can be subsequently added to the volume) or to allow multi-session (additional information may be subsequently added to the volume). An FSC may allow packet-writing, if supported by the media and file system specified in the profile.

Note

A multiple volume (i.e., a logical volume that can cross multiple physical media) is not supported by this class of Application profile. If a set of Files, e.g., a Study, cannot be written entirely on one physical volume (side of one piece of media), the FSC will create multiple independent DICOM File Sets such that each File Set can reside on a single physical volume (side of a single piece of media) controlled by its individual DICOMDIR file. The user of the FSC can opt to use written labels on the physical volumes to indicate that there is more than one physical volume for this set of files (e.g., a study).

H.2.1.2 File Set Reader

The role of File Set Reader shall be used by Application Entities that receive a transferred File Set under the Image Interchange Class of Application Profiles. Typical entities using this role would include image generating systems, display workstations, and archive systems that receive a patient record; e.g., transferred from another institution.

File Set Readers shall be able to read the DICOMDIR directory file and all the SOP Instance files defined for this Application Profile, for which a Conformance Statement is made, using all the defined Transfer Syntaxes for the Profile.

Note

All Transfer Syntaxes defined in the profile must be supported by the FSR. It is not permissible to only support one or other of the uncompressed or the compressed Transfer Syntaxes.

H.2.1.3 File Set Updater

The FSU role is not defined for the STD-GEN-DVD and STD-GEN-SEC-DVD profiles.

H.3 STD-GEN-DVD and STD-GEN-SEC-DVD Profile Classes

H.3.1 SOP Classes and Transfer Syntaxes

This Application Profile is based on the Media Storage Service Class (see PS3.4).

The SOP Classes and corresponding Transfer Syntax supported by this Application Profile are specified in the Table H.3-1. The supported Storage SOP Class(es) shall be listed in the Conformance Statement using a table of the same form.

H.3.2 Physical Medium and Medium Format

The STD-GEN-DVD and STD-GEN-SEC-DVD application profiles require any of the 120 mm DVD media other than DVD-RAM, as defined in PS3.12.

H.3.3 Directory Information in DICOMDIR

Conformant Application Entities shall include in the DICOMDIR File the Basic Directory IOD containing Directory Records at the Patient and the subsidiary Study and Series levels, appropriate to the SOP Classes in the File Set.

All DICOM files in the File Set incorporating SOP Instances defined for the specific Application Profile shall be referenced by Directory Records.

Note

DICOMDIRs with no directory information are not allowed by this Application Profile.

All implementations shall include the DICOM Media Storage Directory in the DICOMDIR file. There shall only be one DICOMDIR file per File Set. The DICOMDIR file shall be in the root directory of the medium. The Patient ID at the patient level shall be unique for each patient directory record in one File Set.

H.3.3.1 Additional Keys

File Set Creators and Updaters are required to generate the mandatory elements specified in PS3.3.

Table H.3-2 specifies the additional associated keys. At each directory record level other additional data elements can be added, but it is not required that File Set Readers be able to use them as keys. Refer to the Basic Directory IOD in PS3.3.

H.3.4 Other Parameters

H.3.4.2 Multi-frame JPEG Format

The JPEG encoding of pixel data shall use Interchange Format (with table specification) for all frames.

H.3.5 Security Parameters

The STD-GEN-SEC-DVD application profiles require that all DICOM Files in the File-set including the DICOMDIR be Secure DICOM Files encapsulated in accordance with the requirements of the Basic DICOM Media Security Profile as defined in PS3.15.

Note

These Application Profiles do not place any consistency restrictions on the use of the Basic DICOM Media Security Profile with different DICOM Files of one File-set. For example, readers should not assume that all Files in the File-set can be decoded by the same set of recipients. Readers should also not assume that all secure Files use the same approach (hash key or digital signature) to ensure Integrity or carry the same originators' signatures.

I DVD MPEG2 Interchange Profiles (Normative)

I.1 Profile Identification

This Annex defines an Application Profile Class for all multi-frame Media Image Storage SOP Classes compressed with MPEG2.

Table I.1-1. STD-DVD-MPEG2-MPML and STD-DVD-SEC-MPEG2-MPML Profiles

Application Profile	Identifier	Description
DVD Interchange with MPEG2 MP@ML	STD-DVD-MPEG2-MPML	Handles interchange of multi-frame images as MPEG2 MP@ML compressed video sequences.
Secure DVD Interchange with MPEG2 MP@ML	STD-DVD-SEC-MPEG2-MPML	Handles interchange of multi-frame images as MPEG2 MP@ML compressed video sequences. Offers confidentiality, integrity and, depending on the File-set creator's choice, data origin authentication.

Equipment claiming conformance to this Application Profile shall list the subset of Media Storage SOP Classes that it supports in its Conformance Statement.

I.2 Clinical Context

This Application Profile Class facilitates the interchange of images data on DVD media. Typical interchange would be between acquisition devices, archives and workstations.

I.2.1 Roles and Service Class Options

This Application Profile Class uses the Media Storage Service Class defined in PS3.4.

The Application Entity shall support one or more of the roles of File Set Creator (FSC) or File Set Reader (FSR), defined in PS3.10. The File Set Updater (FSU) role is not defined.

I.2.1.1 File Set Creator

The role of File Set Creator shall be used by Application Entities that generate a File Set under this Image Interchange Class of Application Profiles.

File Set Creators shall be able to generate the Basic Directory SOP Class in the DICOMDIR file with all the subsidiary Directory Records related to the Image SOP Classes stored in the File Set. The Application Entity acting as a File Set Creator generates a File Set under a STD-DVD-MPEG2-MPML or STD-DVD-SEC-MPEG2-MPML Application Profile.

FSC shall offer the ability to either finalize the physical volume at the completion of the most recent write session (no additional information can be subsequently added to the volume) or to allow multi-session (additional information may be subsequently added to the volume). An FSC may allow packet-writing, if supported by the media and file system specified in the profile.

Note

A multiple volume (i.e., a logical volume that can cross multiple physical media) is not supported by this class of Application profile. If a set of Files, e.g., a Study, cannot be written entirely on one physical volume (side of one piece of media), the FSC will create multiple independent DICOM File Sets such that each File Set can reside on a single physical volume (side of a single piece of media) controlled by its individual DICOMDIR file. The user of the FSC can opt to use written labels on the physical volumes to indicate that there is more than one physical volume for this set of files (e.g., a study).

I.2.1.2 File Set Reader

The role of File Set Reader shall be used by Application Entities that receive a transferred File Set under the Image Interchange Class of Application Profiles. Typical entities using this role would include image generating systems, display workstations, and archive systems that receive a patient record; e.g., transferred from another institution.

File Set Readers shall be able to read the DICOMDIR directory file and all the SOP Instance files defined for this Application Profile, for which a Conformance Statement is made, using all the defined Transfer Syntaxes for the Profile.

I.2.1.3 File Set Updater

The FSU role is not defined for the STD-DVD-MPEG2-MPML and STD-DVD-SEC-MPEG2-MPML profiles.

I.3 STD-DVD-MPEG2-MPML and STD-DVD-SEC-MPEG2-MPML Profile Classes

I.3.1 SOP Classes and Transfer Syntaxes

I.3.2 Physical Medium and Medium Format

The STD-DVD-MPEG2-MPML and STD-DVD-SEC-MPEG2-MPML application profiles require any of the 120 mm DVD media other than DVD-RAM, as defined in PS3.12.

I.3.3 Directory Information in DICOMDIR

Conformant Application Entities shall include in the DICOMDIR File the Basic Directory IOD containing Directory Records at the Patient and the subsidiary Study and Series levels, appropriate to the SOP Classes in the File Set.

All DICOM files in the File Set incorporating SOP Instances defined for the specific Application Profile shall be referenced by Directory Records.

Note

DICOMDIRs with no directory information are not allowed by this Application Profile.

All implementations shall include the DICOM Media Storage Directory in the DICOMDIR file. There shall only be one DICOMDIR file per File Set. The DICOMDIR file shall be in the root directory of the medium. The Patient ID at the patient level shall be unique for each patient directory record in one File Set.

I.3.3.1 Additional Keys

File Set Creators and Updaters are required to generate the mandatory elements specified in PS3.3.

Table I.3-2 specifies the additional associated keys. At each directory record level other additional data elements can be added, but it is not required that File Set Readers be able to use them as keys. Refer to the Basic Directory IOD in PS3.3.

Note

The requirements with respect to the mandatory DICOMDIR keys in PS3.3 imply that either these attributes are present in the Image IOD, or they are in some other way supplied by the File-set Creator. These attributes are (0010,0020) Patient ID, (0008,0020) Study Date, (0008,0030) Study Time, (0020,0010) Study ID, (0020,0011) Series Number, and (0020,0013) Instance Number.

I.3.4 Security Parameters

The STD-DVD-SEC-MPEG2-MPML application profiles require that all DICOM Files in the File-set including the DICOMDIR be Secure DICOM Files encapsulated in accordance with the requirements of the Basic DICOM Media Security Profile as defined in PS3.15.

Note

These Application Profiles do not place any consistency restrictions on the use of the Basic DICOM Media Security Profile with different DICOM Files of one File-set. For example, readers should not assume that all Files in the File-set can be decoded by the same set of recipients. Readers should also not assume that all secure Files use the same approach (hash key or digital signature) to ensure Integrity or carry the same originators' signatures.

I.3.5 "dual-format" (informative)

It is desirable that consumer DVD players (and computer software for playing conventional DVD movies) be able to play the video data that is encoded on the DICOM DVD. The MPEG2 bit stream that is "encapsulated" by the DICOM Transfer Syntax is potentially re-usable by such applications, if the appropriate UDF structure is created to share the same extent between the DICOM file and the file format and folder structure used by the consumer DVD Video format. Alternatively, the bit stream could be duplicated and both sets of files present on the same piece of media.

This profile does not require this, nor specify which approach to take. Specifically, this profile does not require that a DVD Video file and folder structure be present, though it is recommended.

J General Purpose USB and Flash Memory With Compression Interchange Profiles (Normative)

J.1 Profile Identification

This Annex defines an Application Profile Class potentially inclusive of all defined Media Storage SOP Classes. This class is intended to be used for the interchange of Composite SOP Instances via USB, CF, MMC or SD media for general-purpose applications.

Equipment claiming conformance to this Application Profile shall list the subset of Media Storage SOP Classes that it supports in its Conformance Statement.

Note

Since it is not required to support all Media Storage Classes the user should carefully consider the subset of supported Media Storage SOP Classes in the Conformance Statements of such equipment to establish effective object interchange.

J.2 Clinical Context

This Application Profile Class facilitates the interchange of images and related data on USB, CF, MMC or SD media. Typical interchange would be between acquisition devices, archives and workstations.

This Application Profile Class facilitates the creation of a multi-modality medium for image interchange, useful for clinical, patient record, teaching and research applications, within and between institutions.

This profile is intended only for general-purpose applications. It is not intended as a replacement for specific Application Profiles that may be defined for a particular clinical context.

J.2.1 Roles and Service Class Options

This Application Profile Class uses the Media Storage Service Class defined in PS3.4.

The Application Entity shall support one or more of the roles of File Set Creator (FSC) or File Set Reader (FSR), or File Set Updater (FSU) defined in PS3.10.

J.2.1.1 File Set Creator

The role of File Set Creator shall be used by Application Entities that generate a File Set under this Interchange Class of Application Profiles.

File Set Creators shall be able to generate the Basic Directory SOP Class in the DICOMDIR file with all the subsidiary Directory Records related to the Image SOP Classes stored in the File Set.

Note

A multiple volume (i.e., a logical volume that can cross multiple physical media) is not supported by this class of Application profile. If a set of Files, e.g., a Study, cannot be written entirely on one physical volume (side of one piece of media), the FSC will create multiple independent DICOM File Sets such that each File Set can reside on a single physical volume (side of a single piece of media) controlled by its individual DICOMDIR file. The user of the FSC can opt to use written labels on the physical volumes to indicate that there is more than one physical volume for this set of files (e.g., a study).

J.2.1.2 File Set Reader

The role of File Set Reader shall be used by Application Entities that receive a transferred File Set under this Interchange Class of Application Profiles. Typical entities using this role would include image generating systems, display workstations, and archive systems that receive a patient record; e.g., transferred from another institution.

File Set Readers shall be able to read the DICOMDIR directory file and all the SOP Instance files defined for this Application Profile, for which a Conformance Statement is made, using all the defined Transfer Syntaxes for the Profile.

Note

All Transfer Syntaxes defined in the profile must be supported by the FSR. It is not permissible to only support one or other of the uncompressed or the compressed Transfer Syntaxes.

J.2.1.3 File Set Updater

The role of File Set Updater is used by Application Entities that receive a transferred File Set under this Interchange Class of Application Profiles and update it by the addition (or deletion) of images or information to (or from) the medium. Typical entities using this role would include image generating systems and workstations that process or modify images.

File Set Updaters shall be able to generate one or more of the SOP Instances defined for this Application Profile, for which a Conformance Statement is made, and to read and update the DICOMDIR file.

Table K.1-1. Dental Application Profile identifiers

Application Profile	Identifier	Description
Dental Radiograph Interchange	STD-DEN-CD	Interchange of dental radiographic images on CD

K.2 Clinical Context

This Application Profile facilitates the interchange of dental data on media. Typical interchanges would be between dental systems, between a dental system and a display workstation, between display workstations, or between a dental system and a data archive. This context is shown in Figure K.2-1.

Figure K.2-1. Dental Clinical Context

The operational use of the media transfer is potentially between private practitioners and an institution, intra-institutional and inter-institutional.

K.2.1 Roles

K.2.1.1 File Set Creator

The role of File Set Creator shall be used by Application Entities that generate a File Set under the STD-DEN-CD Application Profile. Typical entities using this role would include dental imaging equipment, workstations, and archive systems that generate a patient record for transfer. File Set Creators shall be able to generate the Basic Directory SOP Class Instance in the DICOMDIR file and Digital Intra-oral X-Ray and Digital X-Ray Image Storage SOP Class Instances in the File Set.

An FSC shall offer the ability to either finalize the disc at the completion of the most recent write session (no additional information can be subsequently added to the disc) or to allow multi-session (additional information may be subsequently added to the disc).

Note

A multiple volume (a logical volume that can cross multiple physical media) is not supported by this Application Profile Class. If a set of Files, e.g., a Study, cannot be written entirely on one CD-R, the FSC will create multiple independent DICOM File-sets such that each File-set can reside on a single CD-R media controlled by its individual DICOMDIR file. The user of the FSC can opt to use written labels on the discs to indicate that there is more than one disc for this set of files (e.g., a study).

K.2.1.2 File Set Reader

The role of File Set Reader shall be used by Application Entities that receive a transferred File Set. Typical entities using this role would include dental systems, display workstations, and archive systems that receive a patient record from a piece of media. File Set Readers shall be able to read the DICOMDIR directory file and all SOP Class Instances defined for this Application Profile, using the defined Transfer Syntaxes.

K.2.1.3 File Set Updater

The role of File Set Updater is not supported by this profile.

L ZIP File Over Email Interchange Profiles (Normative)

L.1 Profile Identification

This Annex defines three Application Profiles for interchange of a DICOM Data Set, encapsulated in a ZIP File, through email.

Two Application Profiles support all defined Media Storage SOP Classes. These are intended to be used for the interchange of Composite SOP Instances via email for general purpose applications. Objects from multiple modalities may be included on the same email. The email may also include non-DICOM objects. One of these general profiles supports encryption of the email.

A detailed list of the Media Storage SOP Classes is defined in PS3.4

The other application profile is specialized for dental applications and adds mandatory requirements for dental images to the general secure email profile.

The specific Application Profiles are shown in Table L.1-1:

Table L.1-1. STD-x-ZIP-MAIL Application Profiles

Application Profile	Identifier	Description
General Purpose ZIP Email	STD-GEN-ZIP-MAIL	Interchange of Composite SOP Instances by email.
General Purpose Secure ZIP Email	STD-GEN-SEC-ZIP-MAIL	Interchange of Composite SOP Instances by encrypted email.
Dental Radiograph ZIP Email	STD-DTL-SEC-ZIP-MAIL	Interchange of dental radiographic images by encrypted email

L.2 Clinical Context

M General Purpose BD With Compression Interchange Profiles (Normative)

M.1 Profile Identification

This Annex defines an Application Profile Class potentially inclusive of all defined Media Storage SOP Classes. This class is intended to be used for the interchange of Composite SOP Instances via BD media for general-purpose applications. Objects from multiple modalities may be included on the same media. Images may be compressed with or without loss using either JPEG or JPEG 2000. And multi-frame images and video may be compressed with MPEG2 Main Profile / Main Level or MPEG2 Main Profile / High Level or MPEG-4 AVC/H.264 High Profile / Level 4.1 or MPEG-4 AVC/H.264 BD-compatible High Profile / Level 4.1; all File Set Readers are required to support decompression of all of the compressed Transfer Syntaxes defined for each Profile.

A detailed list of the Media Storage SOP Classes that may be supported is defined in PS3.4.

Table M.1-1. STD-GEN-BD and STD-GEN-SEC-BD Profiles

Equipment claiming conformance to this Application Profile shall list the subset of Media Storage SOP Classes that it supports in its Conformance Statement.

Note

Since it is not required to support all Media Storage Classes the user should carefully consider the subset of supported Media Storage SOP Classes in the Conformance Statements of such equipment to establish effective object interchange.

M.2 Clinical Context

This Application Profile Class facilitates the interchange of images and related data on BD media. Typical interchange would be between acquisition devices, archives and workstations.

This Application Profile Class facilitates the creation of a multi-modality medium for image interchange, useful for clinical, patient record, teaching and research applications, within and between institutions.

This profile is intended only for general-purpose applications. It is not intended as a replacement for specific Application Profiles that may be defined for a particular clinical context.

Note

The creation of a BD is considerably more complex than the reading thereof. Therefore the clinical context for this Application profile is likely to be asymmetric, with a sophisticated File Set Creator and relatively simple File Set Readers.
Each BD Rewritable/Recordable contains a unique ID, which can be read by a BD drive. This ID can be used for referring to a BD, for example in a database.

M.2.1 Roles and Service Class Options

This Application Profile Class uses the Media Storage Service Class defined in PS3.4 with the Interchange Option.

The Application Entity shall support one or more of the roles of File Set Creator (FSC) or File Set Reader (FSR), or File Set Updater (FSU) defined in PS3.10.

M.2.1.1 File Set Creator

The role of File Set Creator shall be used by Application Entities that generate a File Set under this Interchange Class of Application Profiles.

File Set Creators shall be able to generate the Basic Directory SOP Class in the DICOMDIR file with all the subsidiary Directory Records related to the Image SOP Classes stored in the File Set. The Application Entity acting as a File Set Creator generates a File Set under a STD-GEN-BD or STD-GEN-SEC-BD Application Profile.

An FSC shall offer the ability to finalize the physical volume at the completion of the most recent write session (no additional information can be subsequently added to the volume), if supported by the media and file system specified in the profile.

Note

A multiple volume (i.e., a logical volume that can cross multiple physical media) is not supported by this class of Application profile. If a set of Files, e.g., a Study, cannot be written entirely on one physical volume (side of one piece of media), the FSC will create multiple independent DICOM File Sets such that each File Set can reside on a single physical volume (side of a single piece of media) controlled by its individual DICOMDIR file. The user of the FSC can opt to use written labels on the physical volumes to indicate that there is more than one physical volume for this set of files (e.g., a study).

M.2.1.2 File Set Reader

The role of File Set Reader shall be used by Application Entities that receive a transferred File Set under the Image Interchange Class of Application Profiles. Typical entities using this role would include image generating systems, display workstations, and archive systems that receive a patient record; e.g., transferred from another institution.

File Set Readers shall be able to read the DICOMDIR directory file and all the SOP Instance files defined for this Application Profile, for which a Conformance Statement is made, using all the defined Transfer Syntaxes for the Profile.

Note

All Transfer Syntaxes defined in the profile must be supported by the FSR. It is not permissible to only support one or other of the uncompressed or the compressed Transfer Syntaxes.

M.2.1.3 File Set Updater

The role of File Set Updater is used by Application Entities that receive a transferred File Set under this Interchange Class of Application Profiles and update it by the addition (or deletion) of images or information to (or from) the medium. Typical entities using this role would include image generating systems and workstations that process or modify images.

File Set Updaters shall be able to generate one or more of the SOP Instances defined for this Application Profile, for which a Conformance Statement is made, and to read and update the DICOMDIR file.

An FSU shall offer the ability to finalize the physical volume at the completion of the most recent write session (no additional information can be subsequently added to the volume), if supported by the media and file system specified in the profile.

Note

If the volume has not been finalized, the File Set Updater will be able to update information assuming there is enough space on the volume to write a new DICOMDIR file, the information, and the fundamental volume control structures. Volume control structures are the structures that are inherent to the standards of the physical volume, see PS3.12.

M.3 STD-GEN-BD and STD-GEN-SEC-BD Profile Classes

M.3.1 SOP Classes and Transfer Syntaxes

This Application Profile is based on the Media Storage Service Class with the Interchange Option (see PS3.4).

M.3.4 Other Parameters

M.3.4.1 Multi-frame JPEG Format

The JPEG encoding of pixel data shall use Interchange Format (with table specification) for all frames.

M.3.5 Security Parameters

The STD-GEN-SEC-BD application profiles require that all DICOM Files in the File-set including the DICOMDIR be Secure DICOM Files encapsulated in accordance with the requirements of the Basic DICOM Media Security Profile as defined in PS3.15.

Note

These Application Profiles do not place any consistency restrictions on the use of the Basic DICOM Media Security Profile with different DICOM Files of one File-set. For example, readers should not assume that all Files in the File-set can be decoded by the same set of recipients. Readers should also not assume that all secure Files use the same approach (hash key or digital signature) to ensure integrity or carry the same originators' signatures.

The Application Entity acting as a File Set Creator generates a File Set under a STD-GEN-BD-MPEG4-LV42 or STD-GEN-SEC-BD-MPEG4-LV42 Application Profile.

An FSC shall offer the ability to finalize the physical volume at the completion of the most recent write session (no additional information can be subsequently added to the volume) , if supported by the media and file system specified in the profile.

Note

A multiple volume (i.e., a logical volume that can cross multiple physical media) is not supported by this class of Application profile. If a set of Files, e.g., a Study, cannot be written entirely on one physical volume (side of one piece of media) , the FSC will create multiple independent DICOM File Sets such that each File Set can reside on a single physical volume (side of a single piece of media) controlled by its individual DICOMDIR file. The user of the FSC can opt to use written labels on the physical volumes to indicate that there is more than one physical volume for this set of files (e.g., a study).

N.2.1.2 File Set Reader

The role of File Set Reader shall be used by Application Entities that receive a transferred File Set under the Image Interchange Class of Application Profiles. Typical entities using this role would include image generating systems, display workstations, and archive systems that receive a patient record; e.g., transferred from another institution.

File Set Readers shall be able to read the DICOMDIR directory file and all the SOP Instance files defined for this Application Profile, for which a Conformance Statement is made, using all the defined Transfer Syntaxes for the Profile.

Note

All Transfer Syntaxes defined in the profile must be supported by the FSR. It is not permissible to only support one or other of the uncompressed or the compressed Transfer Syntaxes.

N.2.1.3 File Set Updater

The role of File Set Updater is used by Application Entities that receive a transferred File Set under this Interchange Class of Application Profiles and update it by the addition (or deletion) of images or information to (or from) the medium. Typical entities using this role would include image generating systems and workstations that process or modify images.

File Set Updaters shall be able to generate one or more of the SOP Instances defined for this Application Profile, for which a Conformance Statement is made, and to read and update the DICOMDIR file.

An FSU shall offer the ability to finalize the physical volume at the completion of the most recent write session (no additional information can be subsequently added to the volume) , if supported by the media and file system specified in the profile.

Note

If the volume has not been finalized, the File Set Updater will be able to update information assuming there is enough space on the volume to write a new DICOMDIR file, the information, and the fundamental volume control structures. Volume control structures are the structures that are inherent to the standards of the physical volume, see PS3.12.

N.3 STD-GEN-BD-MPEG4-LV42 and STD-GEN-SEC-BD-MPEG4-LV42 Profile Classes

N.3.1 SOP Classes and Transfer Syntaxes

This Application Profile is based on the Media Storage Service Class with the Interchange Option (see PS3.4).

Table N.3-1. STD-GEN-BD-MPEG4-LV42 and STD-GEN-SEC-BD-MPEG4-LV42 SOP Classes and Transfer Syntaxes

Information Object Definition	SOP Class UID	Transfer Syntax and UID	FSC Requirement	FSR Requirement	FSU Requirement
Basic Directory	1.2.840.10008.1.3.10	Explicit VR Little Endian Uncompressed 1.2.840.10008.1.2.1	Mandatory	Mandatory	Mandatory
Multi-frame Composite IODs for which a Media Storage SOP Class is defined in PS3.4	See PS3.4	MPEG-4 AVC/H.264 High Profile / Level 4.2 For 2D Video 1.2.840.10008.1.2.4.104	Defined in Conformance Statement	Mandatory for all SOP Classes defined in Conformance Statement	Defined in Conformance Statement
Multi-frame Composite IODs for which a Media Storage SOP Class is defined in PS3.4	See PS3.4	MPEG-4 AVC/H.264 High Profile / Level 4.2 For 3D Video 1.2.840.10008.1.2.4.105	Defined in Conformance Statement	Mandatory for all SOP Classes defined in Conformance Statement	Defined in Conformance Statement
Multi-frame Composite IODs for which a Media Storage SOP Class is defined in PS3.4	See PS3.4	MPEG-4 AVC/H.264 Stereo High Profile / Level 4.2 1.2.840.10008.1.2.4.106	Defined in Conformance Statement	Mandatory for all SOP Classes defined in Conformance Statement	Defined in Conformance Statement

The SOP Classes and corresponding Transfer Syntax supported by this Application Profile are specified in the Table N.3-1. The supported Storage SOP Class(es) shall be listed in the Conformance Statement using a table of the same form.

N.3.2 Physical Medium and Medium Format

The STD-GEN-BD-MPEG4-LV42 and STD-GEN-SEC-BD-MPEG4-LV42 application profiles require any of the 120 mm BD media, as defined in PS3.12.

N.3.3 Directory Information in DICOMDIR

Conformant Application Entities shall include in the DICOMDIR File the Basic Directory IOD containing Directory Records at the Patient and the subsidiary Study and Series levels, appropriate to the SOP Classes in the File Set.

All DICOM files in the File Set incorporating SOP Instances defined for the specific Application Profile shall be referenced by Directory Records.

Note

DICOMDIRs with no directory information are not allowed by this Application Profile.

All implementations shall include the DICOM Media Storage Directory in the DICOMDIR file. There shall only be one DICOMDIR file per File Set. The DICOMDIR file shall be in the root directory of the medium. The Patient ID at the patient level shall be unique for each patient directory record in one File Set.

N.3.3.1 Additional Keys

File Set Creators and Updaters are required to generate the mandatory elements specified in PS3.3.

Table H.3-2 specifies the additional associated keys that shall also be applicable to the profiles defined in this Annex. At each directory record level other additional data elements can be added, but it is not required that File Set Readers be able to use them as keys. Refer to the Basic Directory IOD in PS3.3.

N.3.4 Security Parameters

The STD-GEN-SEC-BD-MPEG4-LV42 application profiles require that all DICOM Files in the File-set including the DICOMDIR be Secure DICOM Files encapsulated in accordance with the requirements of the Basic DICOM Media Security Profile as defined in PS3.15.

Note

These Application Profiles do not place any consistency restrictions on the use of the Basic DICOM Media Security Profile with different DICOM Files of one File-set. For example, readers should not assume that all Files in the File-set can be decoded by the same set of recipients. Readers should also not assume that all secure Files use the same approach (hash key or digital signature) to ensure integrity or carry the same originators' signatures.
