Eyecare measurements templates
This Supplement proposes to add templates, context groups,
and coded vocabulary for eyecare measurements to the
Standard.
These templates may be used in either SR documents, or for
structured content in an Encapsulated PDF object.
The focus of this Supplement is the set of “key”
measurements clinically important for patient care. These
are not intended to be a comprehensive set of ophthalmic
measurements, although the extensible context groups and
templates allow additional measurements beyond the
specified key measurements to be included in SOP
Instances.
The key measurements of this Supplement are primarily
derived from analysis of images, in particular retinal
optical coherence tomography (OCT) images. Note that there
are several existing IODs that record measurements
directly produced by various refractive devices that do
not produce images (autorefraction, lensometry,
keratometry, etc.), as well as more comprehensive visual
field and macular thickness reports, which are not
intended to be replaced by these more summary key
measurement templates.
There is tension in clinical documentation between the
needs for structured discrete data and human-readable
content. In DICOM, discrete data is generally sent using
Structured Reporting, and ready for display rendered data
may be sent in an Encapsulated PDF.
A given set of measurements may be sent in objects in both
formats, with cross-reference to the other object using
the Referenced Instance Sequence (0008,114A); note that
the cross-reference is to an instance as a whole, not to
individual measurements. Alternatively, discrete
measurements may be included in an Encapsulated PDF object
in the SR-like Content Sequence (0040,A730).
The Templates defined in this Supplement may be used in
either object type.
The DICOM Standard does not recommend the use of any
particular approach to meeting the clinical documentation
needs of the users.
Such recommendation may be made by a professional society
or a standards profiling effort. For example, the American
Academy of Ophthalmology and the IHE Eyecare domain,
considering the need to integrate legacy PDF-based
systems, have in the past recommended use of Encapsulated
PDF with the included SR-like Content Sequence for basic
interoperability, but those recommendations may not meet
all use cases in the evolving interoperable healthcare IT
environment.
This supplement was voted ready as Final Text and to be
incorporated into the next publication of the standard
(2025c).

DICOMweb Modality Procedure Step Services
This supplement adds the Modality Scheduled Procedure Step
Service and the Modality Performed Procedure Step Service
to DICOMweb to mirror the Modality Worklist (MWL) and
Modality Performed Procedure Step (MPPS) services that are
already available in DIMSE respectively.
The modality procedure step services have been designed
with the intention of facilitating proxies from/to
DIMSE.
This supplement was voted ready to go out for Letter Ballot.

Ultrasound Fetal Anatomy Survey SR Extensions
This supplement to the DICOM Standard introduces new SR
template content to address fetal anatomy survey
assessments in ultrasound reports.
Specifically, a sub-template is added to TID 5000 along
with corresponding CIDs to address the anatomy of interest
and assessments for each.
Clinical guidelines from the International Society of
Ultrasound in Obstetrics and Gynecology (ISUOG) call for a
survey of fetal anatomy in the first, second, and third
trimesters to identify structural anomalies.
In Japan, JSUM guidelines call for first and second
trimester anatomical surveys
The guidelines identify specific lists of anatomy to
consider.
This supplement was voted ready to go out for Public
Comment.

2D Total Body Photography
Total Body Photography (TBP) aims to image a person’s
entire skin surface.
TBP is predominantly used for sequential screening for
skin cancer diagnosis, in particular melanoma, but can
also be used for the assessment of inflammatory skin
diseases such as psoriasis.
TBP may improve the accuracy of skin cancer diagnosis
while reducing the number of biopsies of benign skin lesions.
TBP uses visible light imaging. TBP may be 2D or 3D. Camera movement
may be manual or automatic.
Image acquisition typically occurs with the patient in
different positions. Multiple regional images are
acquired to image entire skin surface.
TBP is often used in combination with dermoscopy.
This supplement introduces TBP Regional Image Information
Object Definition (IOD) for imaging of a skin
region.
This supplement will be further presented and
discussed in the base standard group before going
out for Public Comments.

DICOMWeb Send
This supplement adds the Send in DICOMweb to mirror the
Move Service that is already available in DIMSE.
The DICOMWeb Send services have been designed with the
intention of facilitating proxies from/to DIMSE.
This supplement will be further presented and
discussed in the base standard group before going
out for Public Comments.

RDSR Informative Annex
This Supplement provides explanatory information on
the creation and usage of RDSR (traditional and
enhanced) within Angiography, Mammography,
Radiography, CT, Dentistry modalities etc.
This supplement excludes Radiopharmaceutical and
Patient Radiation Dose SR.
Given the modality-specific content definition of
the RDSR, and the many different types of system
configurations existing in the field, it becomes
challenging for the manufacturers to have a clear
understanding of the precise requirements for each
type of device.
The purpose of this supplement can be summarized as
follows:
- Give more information beyond the definitions
in PS 3.16: describe real-world scenarios of
typical equipment configurations, provide
examples and encoding guidelines;
- Indicate restrictions on the applicable
scenarios (defined terms recommended, values
ranges, recommended presence of Content
Items);
- Promote usage of optional Content Items
under particular scenarios;
- Assess the applicability for some
conditional Content Items under particular
scenarios;
The scope of the proposed Supplement includes:
- An overview of the landscape of different
modalities and types of equipment
configuration, from simple legacy CR to
modern integrated Angio equipment.
- Guidance on how to use the different TIDs
and Content Items depending on the modality,
equipment types and configurations.
This supplement will be further presented and
discussed in the base standard group before going
out for Public Comments.
