Current progress is shown below from the most recent meeting of the
DICOM Base Standard (WG-06).
WG-06 meets five times a year to do technical review and harmonization of the output from the 31 DICOM Working Groups.
These DICOM supplements add new "chapters" to the standard and the grouped DICOM change proposals, called CPacks, contain minor tweaks or bug fixes.
Please notice the potential high impact change proposal. It will affect many implementations.
It proposes to substitute retired SNOMED codes for new ones throughout the DICOM standard.
It is cirulated for special public comment due to its scope and content.
This supplement defines transfer SOP classes for physician intent and segment annotations for a new generation of radiotherapy (RT) objects.
This supplement lays out the foundation for additional supplements covering all the necessary new RT objects.
Important aspects during the development of the new RT objects included:
One important focus was on the definition of codes.
The new Content Item Modifier Macro was discussed in detail.
Further progress will be presented in a later base standard meeting before going to final text.
This supplement introduces IODs that describe the administration of imaging agents. The supplement applies to all modalities in which imaging agents are introduced into a subject's circulatory system in a controlled fashion (e.g., CT, MR and XA).
The new SOP Classes describe administration events, flows, pressure, timings, physio-chemical attributes and pharmacological attributes of the agent administration and consumables related to the administration.
These SOP classes do not describe administration of radiopharmaceuticals, which is addressed by R-RDSR.
Focus was put on reviewing codes in the document.
Further progress, especially the example use cases, will be presented in a later base standard meeting before going to final text.
This supplement re-documents (rewrites) PS3.18 Web Services.
The goals of this re-documentation are:
The most important aspect of the re-documentation is that no technical requirements of PS3.18 have been changed. Errors, ambiguities, and underspecified aspects of the current PS3.18 have been corrected through the CP process prior to the finalization of this supplement.
Focus was put on reviewing chapter 10.
Further progress will be presented in a later base standard meeting before going out for letter ballot.
This Supplement extends the CT Image IOD and Enhanced CT Image IOD to support new types of images generated by Multi-energy (ME) CT scanners.
It describes various ME imaging techniques. While different vendors apply different techniques to achieve Multi-energy images, there is large commonality in the generated diagnostic images. It adapts existing attributes of the CT / Enhanced CT IOD to fit ME techniques.
Multi-energy CT acquires pixel information, which correlates to different X-Ray spectra to enable differentiation, quantification and classification of different types of tissues.
To detect the different X-Ray spectra, Multi-energy (ME) CT imaging uses combinations of different Source(s) and Detector(s) technologies such as current switching X-Ray tubes, spectral detectors, multi-layer detectors, multi-source and detector pairs.
Multi-energy CT data can be reconstructed and processed in different ways to serve a variety of purposes.
The presentation and discussion with the base standard group focused on codes and examples.
The supplement was voted to go out for Letter Ballot.
This Supplement describes new DICOM IODs and associated transfer syntaxes for the transport of real-time video and/or audio and associated medical data. These are referred to collectively DICOM Real-Time Video (DICOM-RTV). The supplement defines an IP-based new DICOM Service for the broadcasting of real-time video to subscribers with a quality of service which is compatible with the communication inside the operating room (OR).
The new Real-Time Video Service supports interoperable devices inside the OR and beyond, enabling a better management of imaging information, impacting directly the quality of care.
Professional video (e.g., TV studios) equipment providers and users have defined in SMPTE (ST 2110 family of standards) a new standardized approach for conveying video and associated information.
SMPTE ST 2110 suite, elaborated on the basis of Technical Recommendation TR03 originated by the VSF (Video Services Forum) is used as a platform.
A clarification is necessary regarding dependencies on the SMPTE standards and SMPTE usage restrictions.
The supplement is will be presented in a upcoming base standard meeting before going out for letter ballot review and voting.
This supplement adds a new Secure Connection profile to make DICOM consistent with the latest recommendations from the Japanese CRYPTREC committee.
The CRYPTREC TLS Profile requires compliance with the IETF BCP 195 Recommendations for Secure Use of Transport Layer Security (TLS) and Datagram Transport Layer Security (DTLS) plus support for the additional cypher suites specified by the CRYPTREC committee. This profile requires that TLS negotiation start with the strong security protection parameters, and allows progressive negotiation of weaker protection down to a specified minimum protection limit.
The CYPTREC committee has extended the BCP195 recommendation by adding cypher-suites that must be available for negotiation, and therefore a new profile beyond those in Supplement 204 is needed.
It was noted that DICOM doesn't regulate which profile level of TLS is used in products.
The supplement was voted to go out for Letter Ballot.
