An overview of the latest progress of the DICOM standard from the recent base standard meeting
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:
Supplement 208 extends the DICOM Standard to better address medical 3D manufacturing and uses of Virtual Reality, Augmented Reality, and Mixed Reality.
These extensions fall in three areas:
This Supplement describes a simplified JSON representation of DICOM Structured Report content to allow AI developers to encode image-derived results.
First, the minimal necessary information for a result payload itself may be encoded in JSON for simplicity and ease of use by AI/ML algorithm developers.
Second, this result JSON is merged with the necessary JSON representation of the composite context and other mandatory, or relevant optional, SR content (such as UIDs, image libraries, hierarchical identification and report status management information), which, when transformed, would result in a valid SR IOD with a template-compliant content.
Third and finally, the JSON is transformed into the traditional binary DICOM SR representation for transport, storage and management in an interoperable form.
The TID 1500 Measurement Report template is central to this supplement and describes a generic pattern that is suitable for encoding AI results.
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.
Using an appropriate tool, a complete and compliant binary Structured Report can be created automatically from the JSON, with the subtleties of DICOM encoding hidden from the user.
Supplement 219 was voted to be ready for Trial Implementation by interested vendors and organisations. The Trial Implementation phase will run for 12 months. The achieved learning from this phase will be incorporated into the supplement before going to Letter Ballot voting.
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 was voted to go out for Public Comment.
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.
Usage of this application/zip payload on interchange media is not addressed.
Supplement 211 was voted to go out for Public Comment.
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.
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 can represent previously addressed acquisition types:
This Supplement defines a pair of storage SOP Classes to distribute defined MR protocols and to record performed MR protocols.
The two storage SOP Classes are:
This Supplement introduces a new IOD and a new storage SOP for encoding and storing dermoscopic images.
Dermoscopy is a diagnostic technique that enables visualization of the morphological structures of the skin.
Dermoscopy (also known as dermatoscopy and epiluminescence microscopy) is a non-invasive, in vivo skin examination that has demonstrated to be an important aid in the early recognition of malignant melanoma and other skin tumors.
Dermoscopy is also used for disease conditions (e.g. inflammatory) other than skin cancer.
A dermoscope is hand-held device that consists of magnifier and light source.
Emitted light can be polarized light or non-polarized.
Dermoscopic examination can be by direct contact with skin or non-contact.
Dermoscopy using non-polarized light require direct contact between the skin and the device.
For direct contact dermoscopy an immersion medium is placed on the skin surface and a glass plate on the dermoscope is placed directly against the skin.
Non-contact dermoscopy does not require the dermoscope to be in contact with the skin surface.
Three techniques are used in dermoscopy:
