A.86.1.1 RT Second Generation Common Information

This section provides a description of the Module structure which is shared by the RT Second Generation IODs.

A.86.1.1.1 RT Second Generation Entity-Relationship Model

The E-R Model in Figure A.86.1.1.1-1 depicts those components of the DICOM Information Model that are relevant to RT Second Generation IODs.

Figure A.86.1.1.1-1. RT Second Generation IOD Information Model

A.86.1.1.1.1 Use of Study and Series in RT Second Generation Radiotherapy

For first generation IODs, no specific semantics are attached to a Study or a Series in RT. Similarly, for RT Second Generation IODs, internal references shall be used to relate and locate SOP Instances rather than making assumptions about how related SOP Instances are grouped into Studies or Series. For practical reasons it may be indicated to create a new Study separate from imaging Studies that are used for radiotherapeutic planning because of billing or reimbursement for Series that contain RT Instances.

Implementers should also note that the DICOM Standard, in general, does place some restrictions on how such SOP Instances should be grouped, as defined in Section A.1.2.3.

For non-image modalities like radiotherapy, the Series may not be the most efficient way to search for objects. Instead, an application might find it easier to use references in the RT Course object, Key Object Selection objects or Unified Worklist Procedure Steps to directly retrieve required Instances rather than search for them.

A.86.1.9 RT Radiation Salvage Record IOD

A.86.1.9.1 RT Radiation Salvage Record IOD Description

The RT Radiation Salvage Record IOD contains the record of a complete or partial fraction of therapeutic radiation delivered using any therapeutic device where recording by the modality-specific RT Radiation Record IOD was not possible.

A device usually creates RT Radiation Record SOP Instances using modality-specific RT Radiation Record IODs and transfers these Instances to a system that captures treatment records. If this process fails (e.g. because of failed transfer operations) and the recorded SOP Instances are not recoverable from the device, the RT Radiation Salvage Record IOD may be used to represent radiation delivery captured by a manual entry of the delivered treatment. Systems providing manual entry capabilities might not be able to create a modality-specific RT Radiation Record SOP Instance covering all device-specific parameters in question and/or the user might not know all the details. Therefore, the modality-specific RT Radiation Record IODs cannot be properly populated. The RT Radiation Salvage Record IOD allows essential information to be recorded.
