Log Summary: Remove duplicate anatomy information in irradiation event data in RDSR
Name of StandardPS3.16
Rationale for Correction:CP 687 added an optional "Anatomical structure" content item (+/- "Laterality") when there was already a mandatory "Target region" content
item present, without explaining the difference between the two.Remove the duplicate "Anatomical structure" and move its "Laterality" child to apply to "Target region".
Correction Wording:
Amend DICOM PS3.16 as follows (changes to existing text are bold and underlined for additions and struckthrough for removals):

Content Item Descriptions
Row 3
If the image generating entity does not assign a DICOM UID to the irradiation event (e.g., for non-digital imaging equipment), the application generating this report shall assign a UID.In the case of non-integrated cassette-based equipment, a standalone Detector will generate UIDs for the Events it observes. If the X-Ray Source component of the equipment also reports information, it too will generate UIDs for the Events it creates. A downstream system (e.g., a workstation or the Dose Information Reporter itself) may combine the two reports into a composite report, and match up the events based on details such as the time information, and use the UIDs of the X-Ray Source.
Row 6
Provide DateTime the application of X-Ray started. This shall correspond to the start of the first irradiation in the Irradiation Event, which defines the starting point for the calculation of Row 36 "Irradiation Duration".
Row 17
The target region is the anatomy exposed.
Row 21
A text definition of the Reference Point (RP) used for RP-related dose values.
Row 22
A coded definition of the Reference Point (RP) used for RP-related dose values
Row 26
People responsible for the administration of the radiation reported in the irradiation event. May include values that would appear in Performing Physicians' Name (0008,1050), Performing Physician Identification Sequence (0008,1052), Operators' Name (0008,1070) and/or Operator Identification Sequence (0008,1072).
