Row 2
|
The DateTime of the beginning of first instance of irradiation in the period defined by the scope of accumulation
|
Row 3
|
The DateTime of the end of the last instance of irradiation in the period defined by the scope of accumulation
|
Row 4
|
Frame of Reference UID identifies the reference coordinate system (RCS) used for this RDSR. This RCS may be defined relative to a point in the room, a point on the equipment, a point on the patient support, etc. This RCS shall be a right-handed Cartesian coordinate system.
All events within the scope of accumulation shall use the same RCS. Changes to the system following geometric calibration or service shall result in a new RCS, which will be identified by a new Frame of Reference UID and shall be put into a separate RDSR.
Note
Note: The images generated over this scope of accumulation will also have an RCS identified by an Frame of Reference UID. The Frame of Reference UID of the images may or may not be the same as the Frame of Reference UID for the RDSR RCS. If it is not the same, registration would be required to relate the two RCSs.
|
Row 5
|
It defines the component that is used to define the origin of the RDSR RCS.
Allows secondary devices used during the same scope of accumulation to more easily make registration to other RCS post acquisition.
|
Row 6
|
The textual description may include a description of the origin and orientation relative to the real-world entity (e.g., the gantry, patient support, rotational isocenter, etc.).
|
Rows 7, 8, 9, 11, 12, 13, 14
|
The subtemplate shall be included at least once for each source if applicable conditions are met.
|
Rows 10, 15
|
The subtemplate shall be included at least once if the conditions are met.
|
Rows 16, 17
|
The subtemplate may be included multiple times to reflect changes across multiple sources or over time
