RT Plan IOD
A.20 RT Plan IOD
A.20.1 RT Plan IOD Description
The focus for this Radiotherapy Plan IOD (RT Plan IOD) is to address the requirements for transfer of treatment plans generated by manual entry, a virtual simulation system, or a treatment planning system before or during a course of treatment. Such plans may contain fractionation information, and define external beams and/or brachytherapy application setups.
A.20.2 RT Plan IOD Entity-Relationship Model
This IOD uses the E-R Model in Section A.1.2, with only the Plan IE below the Series IE.
A.20.3 RT Plan IOD Module Table
Table A.20.3-1 specifies the Modules of the RT Plan IOD.

A.20.3.1 RT Fraction Scheme Module
The RT Fraction Scheme Module is structured to be used together with the RT Beams Module or RT Brachy Application Setups Module. If beams are referenced in the RT Fraction Scheme Module, all such beams shall be included in the RT Beams Module if it is present. Similarly, if brachy application setups are referenced in the RT Fraction Scheme Module, all such setups shall be included in the RT Brachy Application Setups Module if it is present. However, the RT Fraction Scheme Module can be used without the RT Beams Module or RT Brachy Application Setups Module if no beams or brachy application setups are referenced, and the RT Beams Module or RT Brachy Application Setups Module can also be used without the RT Fraction Scheme Module if no fraction scheme information is available.
A.20.3.2 RT Prescription Module
The RT Prescription Module provides for the inclusion of dose prescription information pertinent to the complete plan, which may comprise several fraction schemes, themselves consisting of many beams.
A.20.3.3 RT Tolerance Tables Module
The RT Tolerance Tables Module provides information concerning machine tolerances as they apply to the whole treatment plan. Tolerances are applied by reference to a tolerance table within the RT Tolerance Tables Module for beams contained within the RT Beams Module.
A.20.3.4 RT Patient Setup Module
The RT Patient Setup Module provides information concerning Patient setup parameters and fixation devices as they apply to the whole treatment plan. Patient setup information within the RT Patient Setup Module is referenced by beams contained within the RT Beams Module.
Section C.8.8.22.1
C.8.8.22.1 PDR (Pulsed Dose Rate) Treatment
In Brachytherapy treatment techniques where Brachy Treatment Type (300A,0202) is PDR, the Brachy Control Point Sequence (300A,02D0) shall consist of 2N Items, where N = Delivered Number of Pulses (3008,0138). Each control point pair shall represent a single pulse and consist of the first control point of the pulse and the last control point of the pulse.
The Brachy Pulse Control Point Delivered Sequence (3008,0173) is consistent with the Brachy Control Point Delivered Sequence (3008,0160) as defined in the enclosing Recorded Channel Sequence (3008,0130) except all control points delivered are listed in this Sequence as opposed to listing only the start and end control points in the Brachy Control Point Delivered Sequence (3008,0160).
