A Transformation Between AIM and DICOM SR

A.1 Scope and Field of Application

NCI AIM objects that are constrained to specific use cases can be transformed to DICOM SR documents that are based on TID 1500.

NCI AIM specifies a generic model for encoding structured information about medical images. The AIM model and its XML encoding are version specific. The version transformed in this document is Version 4 [Extending AIM]. Though AIM instances can be generated according to application-specific templates [ref. AIM template builder], such templates are too use-case specific to be detailed in the transformation described in this Part. Rather, common patterns of use implemented by well known implementations (ref. CC, ref ePAD) have been abstracted and are mapped as described in this document.

DICOM SR specifies a generic model for encoding structured information about DICOM instances. DICOM TID 1500 Measurement Report specifies a basic DICOM SR report template for quantitative measurements and categorical statements for single identifiable patient subjects including regions of interest defined by spatial coordinates or segmentations.

A.2 Use Cases

The basic use case for the transformation from AIM to DICOM SR is exchange of quantitative and categorical information about DICOM images and regions of interest in DICOM images.

AIM and DICOM SR instances both contain references to DICOM images, and both make use of references to other types of DICOM instances such as segmentations. The flow of information between systems that might make use of a conversion between AIM and DICOM SR instances is considered in Figure A.2-1.

Figure A.2-1. Annotation Creation and Transformation

Various different transformation scenarios should be considered:

Transformation of a complete AIM instance to a complete DICOM SR Measurement Report. The receiver optionally selects relevant parts of the transformed document for further processing or static or interactive visualization by the user.
Transformation of a subset of a AIM instance to a DICOM SR Measurement Report. This subset comprises the relevant information for a specific use-case.
Transformation of multiple related AIM instances to a single DICOM SR Measurement Report. The selected related AIM instances comprise the relevant information for a specific use-case.

This Part of the Standard does not mandate any particular transformation scenario. Transformations of various compatible components of AIM and DICOM SR TID 1500 are described, allowing each of these scenarios to be implemented as appropriate. This Part of the Standard enables a deterministic transformation of the first scenario (complete mapping of an AIM instance to DICOM).

The primary use-case for the transformation is that of:

taking an existing AIM instance containing one or more annotations, converting it into DICOM SR, storing it in a DICOM storage system, possibly displaying it with a DICOM SR aware application, transforming it back into an AIM instance after retrieval from the DICOM storage system, and reusing it in an AIM-aware application

An important secondary use-case is transformation of annotation information in different formats into a single format for data aggregation (e.g., "analytics", "data mining", "big data", "machine learning", and "deep learning"). The conversion described here is intended to allow preservation of semantics sufficient for such purposes, regardless of the source format.

It should be understood that DICOM SR created by transforming an AIM object will not necessarily be identical in structure and content to a DICOM SR that might have been created de novo by a similar application. For instance, there are various encoding choices that an application implementer may make, especially with respect to the degree of post-coordination of ROI and measurement descriptions, which might result in different structures. It may not be possible to transform a DICOM SR TID 1500 instance into AIM and retain all of its content. Post-coordinated concepts, such as measurement and derivation methods, may be preserved by using multiple CalculationEntity/typeCode entries or by pre-coordinating into a single concept during the transformation.

Multiple regions of interest, or multiple measurements and categorical statements about a single region of interest, or about the same real world entity (e.g., lesion) identified with different regions of interest (e.g., at different time points or with different modalities), may be encoded in single or multiple AIM or DICOM SR instances. Whether or not a source AIM or DICOM SR implementation encodes more than one region of interest (and their accompanying measurements and categorical statements) in a single instance or in separate instances, and whether the conversion from one form to the other "bundles" multiple instances into a single instance, or "unbundles" a single instance into multiple instances, is not prescribed. The AIM 4.2 model allows for the encoding of multiple marked up regions and multiple measurements in a single annotation instance, and unlike earlier AIM model versions provides mechanisms for identifying which markup is associated with which measurement using AIM statements; otherwise it is necessary to assume that all markup applies to all measurements and vice versa.

For example, for RECIST measurements that involve the long and short axis of a lesion, it is not only possible to encode in AIM (and map to TID 1500) the boundaries of and the area measurements derived from a planar volumetric ROI, it is also possible to encode the endpoints of the measured axes of the pair of linear measurements and their derived values.

A.3 Structure of DICOM SR Documents

DICOM SR documents can be thought of as consisting of a document header and a document body. The header metadata Attribute values are grouped into Modules such as "Patient", "General Study" in PS3.3.

The SR Document Content Module (Section C.17.3 in PS3.3 ) contains the Attributes for the root Content Item, which includes the coded report title. The Content Tree (structured content) of the document body is contained in the nested Content Sequence Items of that Module. "Container" Content Items are part of the Content Sequence. They are structural elements of the SR document body structure. Content items are DICOM SR document nodes within the Content Tree that are connected through "by-value" relationships (for Enhanced SR IODs). The transformations defined in this Part do not support the use of "by-reference" relationships between Content Items.

Figure A.3-1. SR Document Structure

A.3.1 Header

The Modules used in a DICOM SR are defined by the Information Object Definition (IOD). A particular DICOM SR template may be encoded using a variety of DICOM SR IODs, depending on the features supported by the template and used by a particular instance. Each SR IOD constrains the Value Types and Relationship Types that are permitted. The Enhanced SR IOD is sufficient to encode TID 1500 instances unless 3D patient-relative coordinates (rather than 2D image-relative coordinates or segmentations) are used to define regions of interest on images, in which case use of the Comprehensive 3D SR IOD or Extensible SR IOD would be required.

Table A.3.1-1 summarizes the Modules common to the SR IODs that can encode the TID 1500 as specified in PS3.3.

Patient Module

The Patient Module specifies the Attributes of the Patient that describe and identify the Patient who is the subject of a Study. This Module contains Attributes of the patient that are needed for interpretation of the Image and are common for all studies performed on the patient.

Clinical Trial Subject Module

The Clinical Trial Subject Module contains Attributes that identify a Patient as a clinical trial Subject.

General Study Module

The General Study Module specifies the Attributes that describe and identify the Study performed upon the Patient.

Patient Study Module

The Patient Study Module defines the Attributes that provide information about the Patient at the time the Study was performed.

Clinical Trial Study Module

The Clinical Trial Study Module contains Attributes that identify a Study in the context of a clinical trial.

SR Document Series Module

The SR Document Series Module defines the Attributes of the SR Document Series. A Series of SR Documents may contain any number of SR Documents.

Clinical Trial Series Module

The Clinical Trial Series Module contains Attributes that identify a Series in the context of a clinical trial.

General Equipment Module

The General Equipment Module specifies the Attributes that identify and describe the piece of equipment that produced a Series of Composite Instances.

SR Document General Module

The SR Document General Module defines the general Attributes of an SR Document Instance. These Attributes identify the SR Document and provide context for the entire document.

SOP Common Module

The SOP Common Module defines the Attributes that are required for proper functioning and identification of the associated SOP Instances.

SR Document Content Module

The Attributes in this Module convey the content of an SR Document. It specifies the root Content Item and the Content Tree (refer to Figure A.3-1).

A.3.2 Document Body

The document body is the information that is stored in the DICOM SR Content Tree. The Content Tree is encoded in the SR Document Content Module.

A.3.2.1 DICOM SR "Measurement Report" Template Structure

TID 1500 is the top-level template of the DICOM SR Measurement Report (PS3.16). It includes sub-templates as shown in Figure A.3.2.1-1.

Figure A.3.2.1-1. Template Structure Summarized from PS 3.16

Note

The use of TID 1001 Observation Context within TID 1000 Quotation is not shown because it is not relevant to the mapping use cases.
The use of TID 311 Measurement Statistical Properties and TID 312 Normal Range Properties within TID 310 Measurement Properties is not shown because it is not relevant to the mapping use cases.
The use of TID 1410 Planar ROI Measurements, TID 1411 Volumetric ROI Measurements, and TID 310 Measurement Properties within TID 1420 is not shown because it is not relevant to the mapping use cases.

A.3.2.2 Mapping Considerations

The goal of this document is to specify a mapping between constrained AIM v4 instances and TID 1500 Measurement Report DICOM SR documents. The following limitations apply to AIM instances that are mapped to DICOM SR Measurement Reports:

Subject Context: The DICOM SR TID 1500 Measurement Report is restricted to cover exactly one patient subject; the mapping of subject context of fetuses, specimens or devices as subjects is out of scope. Small or large animal identifiers and descriptors (beyond reuse of the normal patient identifiers) are not specifically addressed since no such identifiers are present in the AIM model (e.g., multiple animals imaged as one, and strain descriptions are out of scope).
The mapping of DICOM SR clinical trial header data (Clinical Trial Subject Module, Clinical Trial Study Module, Clinical Trial Series Module) is not described since no such identifiers are present in the AIM model.
The transformation of de-identified objects is not specifically addressed in this mapping, since AIM does not address encoding of the history of de-identification explicitly. I.e., identifiers will be converted unchanged and whether they have been de-identified will not be explicitly signaled.
A subset of spatial coordinate types are mapped, to the extent that both AIM and DICOM SR support the same graphic concepts.

A.3.2.3 DICOM Composite Object References

The hierarchical Attributes describing DICOM composite object references are used whenever DICOM composite objects are referenced in the Content Tree and are also described in the Image Library templates and the Current Requested Procedure Evidence Sequence (0040,A375) or Pertinent Other Evidence Sequence (0040,A385). Information on relevant DICOM objects referenced within the AIM instance are included in the AIM DicomImageReferenceEntity class.

A.4 Structure of AIM Version 4 Instances

AIM instances are encoded in XML according to a schema generated from the AIM Model [AIM Model v4.2], which is defined in UML. Figure A.4-1 is a simplified view rather than the entire model, showing only those UML classes and attributes relevant to the transformations described in this Part.

Figure A.4-1. AIM v4 Instance Structure

A.5 AIM v4 Structure

Version 4 of AIM makes use of [ISO 21090] data types. See Section A.8 “Overview of Data Types”.

A.6 AIM v4 to DICOM TID 1500 Mapping

The transformation is described in one direction, by enumerating the structures in the target (DICOM SR TID 1500) and describing where in the source (AIM v4) the corresponding information may be obtained. The information is tabulated in a manner that can be implemented as an automated "pull" conversion of an AIM instance into a DICOM SR instance, such as might be described using a transformation language such as XSLT. The transformation is intended to be reversible, i.e., by inverting the target and the source, even though round-trip full fidelity will not be achieved in some cases. Gaps that exist in the information required in the target to create a compliant object, which need to be filled by information from an out of band source or generated de novo , are highlighted. Information in the source that is not "pulled" into the DICOM encoding will be lost; these omissions are deemed to be harmless from the perspective of the relevant use cases.

The tabular representations make use of the following conventions in order to simplify the automatic extraction and use as a formal syntax to drive implementations:

DICOM Attributes are represented by keywords defined in PS3.6, rather than specifying the data element group and element tags.
DICOM Attributes that are nested within sequences are shown as a path from the top level Data Set separated by a ">" symbol.
AIM classes, attributes and associations are represented using their XPath representation as encoded in XML instances.
DICOM Code Sequence Attributes are mapped from AIM CD data type attributes without fully enumerating the corresponding subordinate DICOM Attributes and XML elements and attributes.
Other DICOM Sequences are listed, without a mapping on the same row, but with the following rows describing the individual DICOM Attributes nested within that Sequence.
All source and target paths are fully qualified relative to the root of the instance in order to make the transformation reversible. I.e., it would be possible to describe some transformations using the descendant-or-self axis XSLT operator ("//") if the source were unambiguous but that would not specify the location reversibly as a target. Accordingly, some of the explicit paths are quite long.
The requirement type for DICOM Attributes is as defined in PS3.3 for Attributes in Modules and Attribute Macros, except that if the containing Module in the IOD is not required, e.g., is U rather than M, then a mandatory (Type 1 or 2) Attribute in a user optional (type U) Module is shown as optional (Type 3).
The data type and cardinality are specified for both the source and the target, to highlight potential mismatches that may occur during transformation. For nested elements and attributes, the multiplicity is expressed as the combination of the multiplicity along the entire path. For example, the aim:name attribute has a multiplicity of 1:1 in an aim:Person class but is associated with the aim:ImageAnnotationClass with a multiplicity of 1 -> 0:1, so the multiplicity is indicated as 0:1, not 1:1, since that is the net effect. The DICOM multiplicity is either the VM for the data element or the number of Sequence Items if the data element is a Sequence.

The XML representation of the AIM UML collapses some associations and classes such that they are encoded as a single element, and this is reflected in the mapping paths. For example, the aim:Person class has an aim:person association from the aim:ImageAnnotationCollection class, so the path to the aim:name attribute is expressed as /ImageAnnotationCollection/person/name, as it appears in the XML instance.
Data type transformations are assumed and are not described further unless there is a specific requirement. For example, conversion from DICOM DA, TM and DT VR Attributes to AIM TS Data Type values is implicit, including extraction/population of the appropriate sub-fields (i.e., only the date portion of a TS is used when creating a DICOM DA value).
If value sets are defined for both AIM and DICOM, then value mappings are described. In some cases, explicit value sets are not defined. For example, aim:Person/sex has no explicitly defined value set but maps to DICOM PatientSex, which does; so if AIM implementations use the DICOM values, and the values are copied, then the transformation without value mapping will be successful, but not otherwise.
When a mapping is defined but no transformation source is available but a value is required, a Generated Value is indicated, which may be a fixed constant (e.g., a Modality value of "SR"), an indication that an empty (zero length) value or sequence is required, or an indication that a new value of the appropriate VR needs to be generated (e.g., a new UID for a UI VR, a new integer for an IS VR, etc.). The need to generate new values will not produce a deterministic result without a memory of previous conversions.
Optional content in the target that has no defined source is not described (e.g., DICOM SeriesDescription in the General Series Module has no correlate in AIM, though it would be useful to populate with a generated value).
When the same DICOM Attribute is described in two different Modules, the more specialized (restrictive) use is described in the mapping tables. E.g., InstanceNumber is Type 3 in the SOP Common Module but Type 1 in the SR Document General Module, so it is only described in the latter.
Capitalization and punctuation of DICOM keywords and AIM class, attribute and association names are significant.

A.6.1 Mapping of Constrained AIM v4

A.6.1.1 Header

General Remarks on the mapping of DICOM header Module Attributes:

SR Document General Module

Mapped AIM objects are considered "unverified", so there is no requirement to record the identity of the Verifying Observer; if the "recording" observer identity is required (aim:user class attributes) it may be mapped to Author Observer Sequence (0040,A078) in the SR Document General Module (and entries in Observation Context in the Content Tree are not needed).
Attributes of the Predecessor Documents Sequence (0040,A360) and Identical Documents Sequence (0040,A525) are not described in this transformation since they are relevant only in the context of a managed DICOM SR document environment and have no correlate in AIM.
Attributes of the Current Requested Procedure Evidence Sequence (0040,A375) and Pertinent Other Evidence Sequence (0040,A385) are described in the transformation and provide the information described in the Hierarchical SOP Instance Reference Macro used to match composite instance references with their Study and Series context; the AIM DicomImageReferenceEntity class performs a similar function.
Attributes of the Equivalent Document Sequence (0040,A090) are not described in the transformation since they are relevant only in the context of the original DICOM SR document.

The name space of the AIM elements is elided, and is implied to be "gme://caCORE.caCORE/4.4/edu.northwestern.radiology.AIM".

SOP Common Module

Timezone Offset From UTC (0008,0201) shall be considered for Attributes of the DICOM SR document that are based on the DA or TM data type (PS3.5). AIM date and time attributes may or may not contain explicit timezone information that may be extracted to populate Timezone Offset From UTC (0008,0201).
The Specific Character Set (0008,0005) is required (Type 1C), if the Basic Graphic Set is expanded or replaced. This is the basis for mapping DICOM character sets to AIM XML Unicode (<?xml version="1.0" encoding="UTF-8"?>).

Note

Ambiguities exist for mapping individual characters to Unicode (e.g., for Japanese characters). Resolution of those issues is beyond the scope of this document. Please refer to Section A.8 for further details on data types and character sets.

A.6.1.1.1 Mapping of DICOM Patient Module

Note

If the annotation concerns a small animal that has been imaged as part of a group of animals in the same image, then the PatientID and other Attributes of this Module will be those of that individual animal, not the group. The AIM 4.2 model can optionally identify the group of animals imaged at the same time that corresponds to the DICOM SourcePatientGroupIdentificationSequence.

A.6.1.1.2 Mapping of DICOM Clinical Trial Subject Module

No mapping of the DICOM Clinical Trial Subject Module is described since no corresponding content is present in the AIM model.

A.6.1.1.3 Mapping of DICOM General Study Module

The AIM 4.2 model provides optional Study identification information. If available, this information shall be used during transformation from AIM to SR, otherwise either a new Study may be generated, or the SR instance derived from the AIM object could be placed in (one of) the Study(ies) referenced by the AIM instance, assuming there are any, which produces a predictable transformation.

If there is more than one DICOM Study referenced by the AIM object and explicit Study identification information (ImageAnnotationCollection/studyInstanceUid) is absent, duplicates of the converted AIM SR instance may be placed in each of the referenced studies (with different SOP Instance UIDs), in which case the IdenticalDocumentsSequence is required in the SR Document General Module; see Section C.17.2.2 “Identical Documents Sequence” in PS3.3 .

A.6.1.1.4 Mapping of DICOM Patient Study Module

No mapping of the DICOM Patient Study Module is described since no corresponding content is present in the AIM model.

A.6.1.1.5 Mapping of DICOM Clinical Trial Study Module

No mapping of the DICOM Clinical Trial Study Module is described since no corresponding content is present in the AIM model.

A.6.1.1.6 Mapping of DICOM SR Document Series Module

The AIM 4.2 model optionally supports the concept that an annotation itself is part of a Series. If available, this information shall be used, otherwise a new Series shall be generated since a converted instance cannot be made part of a referenced image Series, if any, because of the rule that all instances of a Series are generated on the same Equipment.

A.6.1.1.10 Mapping of DICOM SR Document Content Module

All the Attributes in the SR Document Content Module are transformed by processing the DICOM SR Content Tree, and accordingly are not described in the same tabular manner as the "header" Attributes, since the mapping depends on the DICOM SR template structure. The Attributes common to each Content Item of the Content Tree are:

ValueType
ConceptNameCodeSequence
ObservationUID
ContentSequence

Each child Content Item with a "by-value" relationship with its parent also contains:

RelationshipType

The additional required Attributes in each Content Item depend on the ValueType:

TEXT - TextValue
DATETIME - DateTime
DATE - Date
TIME - Time
PNAME - PersonName
UIDREF - UID
NUM - MeasuredValueSequence, MeasuredValueSequence>NumericValue, MeasuredValueSequence>MeasurementUnitsCodeSequence
CODE - ConceptCodeSequence
COMPOSITE - ReferencedSOPSequence, ReferencedSOPSequence>ReferencedSOPClassUID, ReferencedSOPSequence>ReferencedSOPInstanceUID
IMAGE - ReferencedSOPSequence, ReferencedSOPSequence>ReferencedSOPClassUID, ReferencedSOPSequence>ReferencedSOPInstanceUID, ReferencedSOPSequence>ReferencedFrameNumber, ReferencedSOPSequence>ReferencedSegmentNumber
SCOORD - GraphicData, GraphicType
SCOORD3D - ReferencedFrameOfReferenceUID, GraphicData, GraphicType
CONTAINER - ContinuityOfContent, ContentTemplateSequence, ContentTemplateSequence>MappingResource, ContentTemplateSequence>TemplateIdentifier

ObservationUID is required for the following Content Items in order to propagate the aim:uniqueIdentifer information:

IMAGE - for (121191, DCM, "Referenced Segment") Content Item corresponding to aim:SegmentationEntity
CONTAINER - for (126200, DCM, "Image Library Group") Content Item corresponding to aim:ImageReferenceEntity
CONTAINER - for (125007, DCM, "Measurement Group") Content Item corresponding to aim:ImageAnnotation
NUM - for any Content Item corresponding to aim:CalculationEntity
SCOORD - for any Content Item corresponding to aim:MarkupEntity

ObservationDateTime is required for the following Content Items in order to propagate the aim:dateTime information:

CONTAINER - for (125007, DCM, "Measurement Group") Content Item corresponding to aim:ImageAnnotation

A.8 Overview of Data Types

DICOM data types are specified in PS3.5 of the Standard (PS3.5).

The AIM V4 data types are a subset of [ISO 21090], which are in turn based on [V3 DT R1]. The AIM V4 data types used are documented in [AIM v3 v4 changes] and [Extending AIM].

While a complete comparison of DICOM and [ISO 21090] data types, cardinality and optionality is beyond the scope of this mapping guide, some hints are given on topics that are relevant for transforming AIM instances and DICOM SR Measurement Reports.

The AIM V4 model uses the data types as specified in Table A.8-2 from [ISO 21090], of which only a subset are encountered in use cases described by this mapping. In XML encoded AIM instances, the data type is not explicitly encoded, though it is defined in the UML model.

Table A.8-1. ISO 21090 Data Types used in AIM V4

ISO 21090 Data Types	Description
BL	Boolean (two-valued logic). A BL value can be either true or false, or may have a nullFlavor.
CD	Concept Descriptor. A reference to a concept defined in an external code system, terminology or ontology, or an expression in some syntax defined by the referenced code system.
II	Instance Identifier. An identifier that uniquely identifies a thing or object. Instance identifiers are usually defined based on ISO object identifiers.
INT	Integer. No arbitrary limit is imposed on the range of integer numbers.
REAL	Fractional numbers. The typical representation is decimal.
ST	Character string. Shall have at least one character or else have a nullFlavor.
TS	Point in time. A quantity specifying a point on the axis of natural time. Most often represented as a calendar expression.

Additional data type mapping considerations include:

Optionality and nullFlavor

If the original AIM instance does not include values that are required or mandatory in DICOM SR TID 1500, fixed values are specified since empty values are not permitted in DICOM SR TEXT and CODE entries and omitting the Content Item would violate the template constraints. All nullFlavor values are treated as empty, except for numeric values.
Character Sets

DICOM provides information on the interpretation of text data types by specifying a default character set (ISO-IR 6) and "Specific Character Set" (0008,0005) values that are used if the Basic Graphic Set is expanded or replaced. For AIM, the XML declaration attribute "encoding" (overall document) and the attribute "charset" (for ST data type values) may be used to provide information on character sets. See the description of Specific Character Set in Section A.6.1.1.11 “Mapping of DICOM SOP Common Module”.
Character strings

In general, ST text value attributes in AIM XML elements are mapped to DICOM Text Value (0040,A160) of value type TEXT (with a VR of Unlimited Text (UT)) in the SR Content Tree. No maximum length is specified for AIM elements and attributes.

Some text value attributes in AIM XML elements are mapped to Attributes in the DICOM header, and DICOM length limits may apply to character strings such as Long String (LO), e.g., Patient ID.
Identifiers

Unique identifiers in AIM V4 are encoded as the root attribute of an XML element (aim:uniqueIdentifier/@root), which has an II data type, and are mapped to the DICOM UI VR, which is limited to 64 bytes.

Codes

Codes in AIM V4 are encoded as attributes of the aim:typeCode XML element and are mapped as specified in Table A.8-2 below for the [ISO 21090] code data type (CD). The code and codeSystemName attributes are encountered as attributes of the aim:typeCode XML element, but the displayName is the value attribute of a child element, aim:typeCode/iso:displayName/@value. Note that codeSystem (Coding Scheme UID) is usually not sent, even though it is required by [ISO 21090]. DICOM also supports other Attributes for encoding code values that exceed 16 characters in length.

Table A.8-2. Mapping between DICOM Basic Code Attributes and AIM ISO 21090 Code Data Types (CD)

DICOM Attribute and VR		AIM Element and Attribute and ISO 21090 Data Type
Code Value (0008,0100)	SH	aim:typeCode/@code	CD.characterstring
Coding Scheme UID (0008,0x010C)	UI	aim:typeCode/@codeSystem	CD.characterstring
Coding Scheme Designator (0008,0102)	SH	aim:typeCode/@codeSystemName	CD.characterstring
Coding Scheme Version (0008,0103)	SH	aim:typeCode/@codeSystemVersion	CD.characterstring
Code Meaning (0008,0104)	LO	aim:typeCode/iso:displayName/@value	CD.ST

Date and Time
- The AIM V4 XML element aim:dateTime/@value attribute corresponds to the ISO 21090 TS data type, and is mapped to the DICOM DateTime (DT) VR, or the combination of separate Date (DA) and Time (TM) Attributes.
- DICOM DT matches TS except for the number of decimal places of fractional seconds (6 for DT versus 4 for TS).
- DICOM DA matches the TS part YYYYMMDD (Y=Year, M=Month, D=Day), except that TS may be missing DD or MMDD.
- DICOM TM matches the TS part HHMMSS.UUUUUU (H=Hour, M=Minute, S=Second, U=Fractional Second) except for the number of decimal places of fractional seconds (6 for DT versus 4 for TS).
- If available, the DICOM Timezone Offset From UTC (0008,0201) used for DA or TM data types may be populated using time zone offset values from the ISO 21090 TS value.
- ISO TS allows for separators; these need to be removed for conversion to DT, DA and TM.

Person Names

DICOM Person Name (PN) shall be mapped from [ISO 21090] data type Person Name (PN) as described in Table A.8-3.

Table A.8-3. Mapping between DICOM Person Name (PN) ans ISO 21090 Data Type Person Name (PN)

DICOM Person Name (PN)	ISO 21090 Data Type: Person Name (PN)
<family_name_complex>	Family Part type
<given_name_complex>	Given Part type
<middle_name>	Given Part type - order of parts matters
<name_suffix>	Suffix Part type
<name_prefix>	Prefix Part type

[ISO 21090] PN may contain multiple given names. DICOM PN Middle Name shall be mapped to [ISO 21090] PN Given Name Part type.
Example A.8-1. Person Name Example
John Robert Morrison, Ph.D. "Morrison^John Robert^^^Ph.D." [One family name; two given names; no middle name; no prefix; one suffix] can be represented as a [ISO 21090] Person Name (PN) in the following way:
```
<name>
   		<given>John</given>
   		<given>Robert</given>
		<family>Morrison</family>
 		<suffix>Ph.D.</suffix>
	</name>
```

The following [ISO 21090] PN use codes may be used to represent multi-part DICOM person names: ABC (Alphabetic), IDE (Ideographic), SYL (Phonetic).

Example A.8-2. HL7 V3 Multi-Part Person Name Example

<name use="ABC">
   		<family>KIMURA</family>
   		<given>MICHIO</given>
	</name>
	<name use='IDE'>
   		<family>木村</family>
   		<given>道男</given>
	</name>
	<name use="SYL">
   		<family>きむら</family>
   		<given>みちお</given>
	</name>

Numeric Measurements

DICOM Numeric Measurement value types shall be mapped from the [ISO 21090] data types as specified in Table A.8-4.

Table A.8-4. Mapping between DICOM Numeric Measurement Value Types and ISO 21090 Data Types

DICOM PS3.3, PS3.5 and PS3.16: Numeric Measurement (NUM) Value Type		AIM Path and ISO 21090 Data Type
Measured Value Sequence (0040,A300) > Concept Name Code Sequence (0040,A043)	Code Sequence Macro	CalculationEntity/typeCode[1]	CD
Measured Value Sequence (0040,A300) > Numeric Value (0040,A30A)	DS	CalculationEntity/calculationResultCollection/CalculationResult/@value CalculationEntity/calculationResultCollection/CalculationResult/calculationDataCollection/CalculationData/@value	ST
Measured Value Sequence (0040,A300) > Measurement Units Code Sequence (0040,08EA)	Code Sequence Macro	CalculationEntity/calculationResultCollection/CalculationResult/unitOfMeasure	ST
Numeric Value Qualifier Code Sequence (0040,A301)	Code Sequence Macro	CalculationEntity/calculationResultCollection/CalculationResult/calculationDataCollection/CalculationData/@value	ST

The [ISO 21090] PQ data type is not used in AIM.

The Concept Name of the measurement is usually pre-coordinated in a single CalculationEntity/typeCode entry. If there is more than one CalculationEntity/typeCode, the first is assumed to be the primary concept and the others may be modifiers that, if recognized as such, may be mapped to method and derivation, or if otherwise recognized and name-value pair of concepts can be constructed can be encoded as generic modifiers, but otherwise have to be ignored.

The Numeric Value may be found as the single value of a CompactCalculationResult (i.e., value child of CalculationResult) or the first value of an ExtendedCalculationResult (i.e., nested within calculationResultCollection). This can give rise to a difference in representation in a round trip conversion.

Units of measurement shall be converted from a text string (ST) to a Coded Sequence entry using the UCUM Code Values and "UCUM" as the Coding Scheme Designator (in AIM, CalculationResult/unitOfMeasure is defined as "A string representation of UCUM unit for the value of the calculation").

The AIM CalculationData/@value shall be assumed to be in the US English locale (i.e., periods are used as the decimal point, not commas, etc.).

The length of the AIM CalculationData/@value ST is not limited, but the DICOM DS value representation is limited to 16 characters. Values of CalculationData/@value that are too long shall be truncated or rounded to fit in an implementation-dependent manner.

The CalculationResult/dataType (e.g., Double, Integer) is not encoded in the DICOM mapping, since all DICOM SR numeric values are encoded as a Decimal String (DS), so in a round trip from AIM to DICOM and back to AIM will not be recovered (i.e., will always be encoded as Double). For the use cases for this mapping, it is likely that all measurements will be Double anyway.

DICOM allows the Measured Value Sequence (0040,A300) to be sent zero length (empty) if there is no value. In such cases the Numeric Value Qualifier Code Sequence (0040,A301) may be used in DICOM to send a code indicating why, either because of an invalid floating point result (e.g., (114000, DCM, "Not a number") corresponding to [IEEE 754] NaN), or for more general reasons (e.g., (114006, DCM, "Measurement failure")). See CID 42 “Numeric Value Qualifier”. Table A.8-4 indicates that a non-numeric CalculationData/@value may be mapped to Numeric Value Qualifier Code Sequence (0040,A301). Various possible mappings of AIM string values to a subset of DICOM codes corresponding to [IEEE 754] are defined in Table A.8-5. These are based on the:

Java Double.toString(double) definition (see https://docs.oracle.com/javase/8/docs/api/java/lang/Double.html#toString-double-)
[XSD Datatypes]
[ISO 21090]

No similar standard C or C++ mapping is known to exist (e.g., for libc dtostr() or sprintf()). Other languages offer some flexibility (e.g., Python supports case insensitive variants of "NaN" and "Infinity", the latter with or without a sign; see http://docs.python.org/3/library/functions.html#float). For JavaScript, see https://tc39.github.io/ecma262/#sec-tostring-applied-to-the-number-type, https://tc39.github.io/ecma262/#sec-parsefloat-string and https://tc39.github.io/ecma262/#sec-number.parsefloat. The table describes a subset of possible values, the mapping may not be exact (e.g., the definitions of NaN may differ), the mapping is ambiguous (since AIM does not define which string source to use), and the mapping of other values is undefined.

Table A.8-5. Mapping between DICOM Numeric Value Qualifier Code Sequence and AIM ST

DICOM Code	Java String	XML Schema	ISO 21090 Null Flavor
(114000, DCM, "Not a number")	NaN	NaN
(114001, DCM, "Negative Infinity")	-Infinity	-INF	NINF
(114002, DCM, "Positive Infinity")	Infinity	INF	PINF

Image and segmentation references

DICOM image references may be mapped as specified in Table A.8-6.

Table A.8-6. DICOM Image references to AIM Path

DICOM PS3.3, PS3.5 and PS3.16: Image Reference (IMAGE) Value Type		AIM Path and ISO 21090 Data Type
Referenced SOP Sequence > Referenced SOP Class UID	UI	/ImageAnnotationCollection/imageAnnotations/ImageAnnotation/imageReferenceEntityCollection/ImageReferenceEntity/imageStudy/imageSeries/imageCollection/Image[sopInstanceUid/@root=imageReferenceUid/@root]/sopClassUid/@root	II
Referenced SOP Sequence > Referenced SOP Instance UID	UI	imageReferenceUid/@root	II
Referenced SOP Sequence > Referenced Frame Number	IS	referencedFrameNumber/@value	INT

An image reference in the AIM tree locally consists of the SOP Instance UID only, without SOP Class, which is described elsewhere in the tree in the imageReferenceEntityCollection (which, similar to the DICOM Current Requested Procedure Evidence Sequence or Pertinent Other Evidence Sequence, also contains the Study and Series level information). Hence the use of the predicate "sopInstanceUid/@root=$sopInstanceUID" in the path in the table.

The AIM version 4.2 model includes an optional AccessionNumber in the imageStudy class used in the imageReferenceEntityCollection. This may be preserved in a DICOM SR instance in the ImageLibrary.

DICOM segmentation references may be mapped as specified in Table A.8-7.

Table A.8-7. DICOM Segmentation references to AIM Path

DICOM PS3.3, PS3.5 and PS3.16: Image Reference (IMAGE) Value Type		AIM Path and ISO 21090 Data Type
Referenced SOP Sequence > Referenced SOP Class UID	UI	SegmentationEntity/sopClassUid/@root	II
Referenced SOP Sequence > Referenced SOP Instance UID	UI	SegmentationEntity/sopInstanceUid/@root	II
Referenced SOP Sequence > Referenced Segment Number	US	SegmentationEntity/segmentNumber/@value	INT

The SOP Class UID is included locally in the AIM tree with the reference, rather than being factored out into the imageReferenceEntityCollection, in which it is not present.

Ideally, all segmentation references would be included in either Current Requested Procedure Evidence Sequence or Pertinent Other Evidence Sequence as appropriate. There is optional information in the AIM 4.2 model to identify the Study and Series, but if the Study and Series Instance UIDs are absent, they cannot be assumed to be those of any related images.

The reference to the original image that was segmented or a representative image on which the segmentation may be displayed, which may be present in SegmentationEntity/referencedSopInstanceUid/@root, may be encoded in a separate Content Item if supported by the template (e.g., TID 1410, TID 1411) in (121233, DCM, "Source image for segmentation").
