Foreword
This Supplement specifies additional IODs necessary to support the new Second Generation 112 Radiotherapy IODs and operations.
Scope and Field of Application 114
Introduction
This Supplement introduces RT Radiation IODs and RT Radiation Set IODs. A Radiation Set IOD 116 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 118 representation of the C-Arm techniques.
This Supplement is based on the real-world model and specifications defined in Supplement 147. 120 References, definitions etc. not present in this Supplement can be found in Supplement 147.
General Architectural Principles 122
• Different types of data are encoded in different IODs. This is in contrast to First Generation objects, where different types of data are encoded in a single IOD, such as RT Plan. 124
• The new IODs are designed to support all current treatment modalities and be extensible for future modalities and new equipment. 126
• 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 128 a First Generation SOP Instance will be needed to create a valid Second Generation SOP Instance. 130
• IODs specific to use cases: Explicit separate IODs have been developed for specific treatment modalities with the concept of RT Radiation IOD – for example, Tomotherapeutic treatments, C-132 Arm beams, Robotic beams 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 134 potential for interoperability.
• Treatment techniques already in use but not yet covered in First Generation (such as robotic 136 therapy and tomotherapy) have been taken into account.

Part 3 Addendum
7.14 EXTENSION OF THE DICOM MODEL OF THE REAL-WORLD FOR RADIOTHERAPY 146
SECOND GENERATION INFORMATION OBJECTS
For the purpose of RT Second Generation SOP Classes the DICOM Model of the Real-World is 148 described in this section. This subset of the real-world model covers the requirements for transferring information about planned and performed radiotherapeutic treatments and associated data. 150
Figure 7.14-1 describes the most important elements involved in the radiotherapy domain in DICOM.

The following is an excerpt from C-Arm for illustration. The content has to be replaced by applicable 290 Brachytherapy content.
The C-Arm Photon-Electron Module defines constant C-Arm-specific parameters pertaining to the 292 physical device used to deliver external ion beams using modulated scanning techniques.

Attribute Name Tag Type Description
Virtual Source-Axis Distances (300A,030A) 1 Distance (in mm) from virtual source position to gantry rotation axis or nominal isocenter position (fixed beam-lines) of the equipment to be used for beam delivery.
Specified by a numeric pair - the VSAD in the IEC Gantry X direction followed by the VSAD in the IEC Gantry Y direction.
The VSAD is commonly used for designing apertures in contrast to the effective source-axis-distance (ESAD) that is commonly used with the inverse square law for calculating the dose decrease with distance.
