Hello all,
There is a letter ballot for Proposed DICOM Supplement 160: Second Generation Radiotherapy – Patient Setup and Delivery Instruction

Scope and Field of Application
- This Supplement specifies two IODs to support workflow management and patient setup for Radiotherapy treatment delivery sessions. The IODs are designed as part of the Second Generation Radiotherapy object framework.
- This Supplement introduces an RT Radiation Set Delivery Instruction IOD, which specifies the RT Radiations to be applied for treatment delivery, the order in which they are applied, and some other parameters related to the upcoming RT Treatment Session.
- This Supplement introduces an RT Treatment Preparation IOD to specify setup devices, setup procedures and other items related to the setup of the patient prior to the delivery of therapeutic radiation. The First Generation RT Plan IOD contained a Patient Setup Module with a similar content. However, this content may change between the treatment sessions, while the majority of content of the RT Plan, defining the treatment parameters, remains the same. This caused unnecessary proliferation of RT Plan SOP Instances, and compromised fraction counting within a series of dosimetrically uniform treatments. Therefore, the Second Generation RT Radiation Set and RT Radiation IODs do not include such content, but use a separate IOD for this purpose.

Information about this supplement can be accessed on the DICOM public server:
