Waveform Presentation State
This supplement introduces Service Classes for
storage and exchange of presentation information for
DICOM waveform objects by adding a Waveform
Presentation State IOD. The Waveform Presentation
State object stores the display montages,
i.e. calculative combinations of recorded channels,
display filter and other display properties as well
as arbitrary Annotations.
This supplement adds
- a new Waveform Presentation State IE.
- a SOP Class to store Waveform Presentation States and the related Modules.
In cardiology, technicians annotate previously recorded waveforms (e.g. from home monitoring Holter ECG) and highlights areas of interest. This information is essential input for the cardiologist who reviews the ECG and finally provides the report.
This supplement will be presented and discussed further in the base standard working group before going to Final Text.

Patient Model Gender Enhancements
This supplement adds a comprehensive gender logical model for sex and
gender representation in DICOM.
This facilitates communication between DICOM and the
various HL7 systems.
The goal is to make the distinction between phenotypical
sex and the patient's social context gender clear.
The approach is to add new optional sequences to the
Patient Study Module.
The DICOM model extensions are consistent with the work in
HL7 and FHIR:
- The HL7 Gender Harmony Project created a logical model to describe
the information needed in an electronic record to support proper
care for gender and sex diverse patients.
- The HL7 model includes both clinical information and
social information.
This supplement also updates Patient Sex (0010,0040) description and
some CIDs to match the HL-7 updated definition.
This supplement will be presented and discussed
further in the base standard working group before
going to Letter Ballot.

Structural Heart SR Template
This supplement introduces SR templates for
Structural Heart Procedures.
These procedures involve interventions aimed at
addressing various conditions or abnormalities
affecting the structures of the heart, excluding the
coronary arteries.
Unlike open-heart surgery, these interventions are
characterized by their minimally invasive nature or
catheter-based approach.
Periprocedural imaging follows a consistent pattern
of three phases: pre-operative assessment,
intraprocedural assessment, and follow-up.
Throughout all three phases, echocardiography
emerges as the primary imaging modality.
X-ray angiography is predominantly utilized for
intraprocedural guidance.
CT may also find application in the pre-operative
assessment and follow-up.
The templates proposed in the supplement are based
the Simplified Adult Echocardiography Templates
(root TID 5300), modified to support multimodality
image acquisition.
Structural Heart Procedures include:
- TAVI: Transcatheter Aortic Valve implantation
- TAVR: Transcatheter Aortic Valve Replacement
- TTVP: Transcatheter Tricuspid Valve Procedure
- TTVR: Transcatheter Tricuspid Valve Repair
- TEER: Transcatheter Edge-to-Edge Repair
- TMVr: Transcatheter Mitral Leaflet Clip Procedure
- TMVR: Transcatheter Mitral Valve Replacement
- LAAC: Left Atrial Appendage Closure

DICOMWeb Modality Services
The DICOMweb Modality Services extends the
existing DICOMweb services, mimicking the Modality
Worklist (MWL) and Modality Performed Procedure Step
(MPPS) services that are already available in
DIMSE.
It has been designed with the intention of facilitating
proxies from/to DIMSE to/from DICOMweb Modality
Services.
This supplement describes the way to perform modality
services MWL and MPPS based on DICOM-web's UPS-RS.
The current main focus in the discussion is on how the
detailed mapping is done. There are many clarification
needed in the mapping on attribute level between MWL and
UPS from the basis blueprint DIMSE services.
This supplement will be further presented and
discussed in WG06 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.

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.
While DICOM has standardized the ophthalmic image formats,
it has not yet standardized the measurements derived from
those 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.).
The measurements of this Supplement are instead derived
from analysis of images, typically retinal optical
coherence tomography images.
This supplement will be further presented and discussed in
WG06 before going out for Public Comments.
