For roles involving irradiation authorization, X-Ray Radiation Dose Structured Report (RDSR) captures the person identity as structured content using the following mechanisms.
In the RDSR Root Templates TID 10001, TID 10011, and TID 10040:
TID 1002 “Observer Context” encodes one or more persons/roles.
TID 1020 “Person Participant” explicitly denominates the person who authorized the X-Ray procedure under the role "Irradiation Authorizing".
In the Irradiation Event X-Ray Data Template TID 10003, CT Irradiation Event Data Template TID 10013, and in the Irradiation Event Summary Data Template TID 10042:
TID 1020 “Person Participant” explicitly denominates the person(s) who performed the image acquisitions and applied X-Ray under the role "Irradiation Administering" (typically the Performing Physician and Operator in X-Ray Angiography).
The physician authorizing the application of radiation (i.e., the person that "justifies" that the irradiation is appropriate for that patient) is not necessarily the same person that administers the radiation during performance of the procedure. Even if it is the same person, the same name will be encoded twice, one for each role.
Table UUUU.4.4.2-1 provides a coding example of an X-Ray Angiography procedure where <name of the authorizer> has authorized the procedure performed by <name of the performing physician>. The system is operated by <name of the operator>assisting in the procedure.
