An overview of the latest progress of the DICOM standard from the recent base standard meeting
This supplement adds realtime video handling to the DICOM standard.
It describes several 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 as DICOM Real-Time Video (DICOM-RTV).
The supplement defines an new IP-based 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).
Professional video (e.g., TV studios) equipment providers and users have defined in SMPTE (ST 2110 family of standards). ST 2110-10 uses a multicast model rather than a peer-to-peer communication model. DICOM-RTV builds upon ST 2110.
DICOM-RTV restricts real-time communication to uncompressed video.
This supplement was voted as Final Text. It will be part of the next edition of the standard.
The scope of this supplement is the introduction of new RT Radiation IODs for non-C-Arm treatment devices.
This supplement adds support for instances of the following RT devices:
The SOP Classes in this document are defined to record how a treatment was performed.
This comprises acquired machine values, measured dose values, overrides, etc.
In addition, recording of a manual implementation of a Radiation is covered.
The scope of this Supplement is on treatment delivery and it introduces the concept of RT Radiation Records.
This Supplement is based on the real-world model and specifications defined in Supplement 147. References, definitions etc. not present in this Supplement can be found in Supplement 147.
Supplement 199 will be further presented and discussed with the Base Working Group in a coming meeting before Public Comment voting.
This supplement focuses on rewriting part two, DICOM conformance, of the standard.
The goal is to achieve better interoperability and machine processing of DICOM conformance statements.
It was considered advantageous if the template is a separate generated MS Word template.
Supplement 209 will be further presented and discussed with the Base Working Group in a coming meeting before Public Comment voting.
Supplement 211 adds the application/zip media type to the RESTful Web Services in PS3.18. It enables retrieving an entire DICOM study or series as a single zip format file.
The primary use case is to enable researchers in analytics / machine learning to use DICOMweb to retrieve studies, series, or other collections of images for training purposes. DICOMweb currently provides a means to retrieve an entire study or an entire series using the multipart/related media type, but this requires special non-browser implementations to retrieve the content because multipart/related is not currently supported by any of the major browsers.
A secondary use case is to provide consumers with browser access to a DICOM study using a ZIP file, which will provide patients or caregivers browser access that is simpler than that provided by a multipart/related response must be programmatically interpreted.
Supplement 211 will be further presented and discussed with the Base Working Group in a coming meeting before Public Comment voting.
This Supplement defines a pair of storage SOP Classes to distribute defined XA protocols and to record performed XA protocols.
This Supplement creates a structured report with the necessary flexibility to address cone-beam CT acquisitions.
This generic radiation description is capable of representing previously addressed acquisition types (Angiography, Mammography, CR/DR, CT).
Radiotherapy treatment dose and radiopharmaceutical dose are out of scope.
Supplement 214 will be further presented and discussed with the Base Working Group in a coming meeting before Public Comment voting.
This Supplement introduces a number of Services Classes for Storage of Neurophysiology Waveforms by adding the related Neurophysiology IODs and the necessary Neurophysiology Waveform Context Groups.
It adds a SOP Class to store routine (clinic) electroencephalography (EEG) data recording the electrical activity of the brain collected on the skull surface using electrode positions of the international 10/10 or 10/20 localization scheme.
It adds a SOP Class to store electromyography (EMG) data recording the electrical activity of skeletal muscles.
It adds a SOP Class to store electrooculography (EOG) data collected near the eyes recording eye movement.
It adds a SOP Class to store generic neurophysiology signals.
It adds a transfer syntax for DICOM waveforms using RED compression.
Supplement 217 will be further presented and discussed with the Base Working Group in a coming meeting before Public Comment voting.
This Supplement describes a simplified JSON representation of DICOM Structured Reports, similar to the PS3.18 JSON representation, to allow AI developers to encode image-derived results.
This supplement describes a mapping between a simple JSON representation of the measurement and annotation result payload expected from an AI system, and the traditional binary DICOM SR encoding of the same information.
This supplement defines a new Part, PS3.22, to contain the alternative representation, and includes the existing Attribute level XML and JSON encodings factored out of PS3.19 and PS3.18.
DICOM PS3.16 defines templates for different applications. The TID 1500 Measurement Report template describes a generic pattern that is suitable for encoding AI results as well as other quantitative and qualitative (categorical or descriptive) results. The JSON representation is exemplified using TID 1500, but the conversion supports full fidelity round-trip encoding of any DICOM SR instance, regardless of the template.
The JSON representation leverages the "business name" concept from HL7 Green CDA, such that simple meaningful strings can be used in the JSON for coded tuples for concept names and values, as well as for DICOM Attributes in the top level Data Set. The business names are defined in a separate, potentially reusable, JSON file.
Supplement 219 will be further presented and discussed with the Base Working Group in a coming meeting before Public Comment voting.
