To: DICOM Standard Committee (DSC) Voting and Alternate Voting Members
Letter Ballot seeking DICOM Standard Committee (DSC) approval of the Proposed DICOM Supplement:
Supplement 175: Second Generation Radiotherapy – C-Arm RT Treatment Modalities

Scope and Field of Application
Supplement 175 (reproduced from the document for convenience:)

This Supplement introduces the RT Radiation IOD and the RT Radiation Set IOD. An RT Radiation Set IOD defines a Radiotherapy Treatment Fraction as a collection of instances of RT Radiation IODs. RT Radiation IODs represent different treatment modalities. This Supplement introduces the representation of the C-Arm techniques.

General Architectural Principles
• Different types of treatment devices are supported by different IODs, for example, C-Arm devices, Tomotherapeutic devices, Multiple Fixed Source devices and Robotic devices are modeled separately. This allows more stringent conditions to be applied to the presence or absence of Attributes within those IODs, and thereby increases the potential for interoperability.
• The Second Generation RT Objects definitions provide the basis to support all current treatment modalities and be extensible for future modalities and new equipment.
•Compatibility with First-Generation IODs: It will be possible for the content of First Generation IODs to be represented in Second Generation IODs. However, information beyond the content of a First Generation SOP Instance will be needed to create a valid Second Generation SOP Instance.

Who can vote? Only the designated Primary voting representatives of the DSC member organizations/companies are invited and entitled to vote. (Votes may also be submitted by the designated Alternate voting representatives, on behalf of the Primary representative.) (Others in the DICOM Community will receive a copy of this ballot as a courtesy so that all will be apprised of anticipated extensions to the DICOM Standard.)
