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.
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.
These include:
Important aspects during the development of the new RT objects included:
The final walk through, line by line reading, of the document was completed. Final discussions, especially around concept volume, are reflected in the document.
The supplement was voted Final Text and is becoming part of the standard.
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) involving both automated and manual administration.
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.
The comprehensive example was presented, discussed and improved. The example is expected to be a great help to implementors.
The supplement was voted Final Text and is becoming part of the standard.
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 Final Text and is becoming part of the standard.
This supplement adds a new Secure Connection profile to make DICOM consistent with the latest recommendations from the Japanese CRYPTREC committee by recommending support for all the ciphersuites included in the CRYPTREC recommendation.
The Extended BCP195 TLS Profile requires compliance with the IETF BCP195 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 CRYPTREC Committee validated the strength of cipher suites and identified 12 cipher suites that can be used with TLS 1.2, including some cipher suites not included in BCP195. In addition, a key length requirement that is stricter than BCP195 is specified.
The supplement was voted Final Text and is becoming part of the standard.
This supplement Re-Documents (rewrites) PS3.18 Web Services.
The goals of this supplement 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.
The supplement was voted ready to go out for Letter Ballot review and voting.
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.
The supplement is will be presented in a upcoming base standard meeting before going out for letter ballot review and voting.
This supplement describes the storage of Paradigm Protocols, the Defined and Performed one. Also adding definition of a Stimuli object for Storage.
Paradigms are used to trigger stimuli used during functional scanning to capture the patient's brain activities.
The flow of events are:
It is a working assumption that there is a paradigm creation app and specialized post processing involved.
Further progress will be presented in a later base standard meeting before going out for public comments.
This supplement adds "application/zip" as an option in the DICOMweb WADO-RS specification, to retrieve an entire DICOM study or series as a single file.
One important use case to extend Part 18 is that researchers in analytics / machine learning users of DICOMweb want to retrieve studies / series / collections of images.
DICOMweb currently provides a mechanism "multipart/related". This requires special non-browser implementations to retrieve the content. There is no general web browser support for "multipart/related"
Additional considerations to consider, such as whether to include support for ZIP encryption, and whether to include flags to support DICOMDIR.
The first presentation was held. The document will be further discussed and presented to the base standard meeting before the public comment phase.
