## OOO.2 Real-World Nuclear Medicine and PET Radiopharmaceutical Radiation Dose (RRD) SR Workflow

Figure OOO-2 demonstrates a Hot Lab management system as the RRD creator. It records the activity amount and the administration time. It creates the RRD report and sends it to the modality. Consistent time is required to accurately communicate activity amount. The consistent time region highlights systems and steps where accurate time reporting is essential. A DICOM Store moves the report to the modality.

Figure OOO-3 demonstrates RRD workflow where a radiopharmaceutical is administered to a patient for a non-imaging procedure. The report is sent to the image manager/image archive for storage and reporting.

Figure OOO-4 demonstrates when an infusion system or a radioisotope generator is the RRD creator.

Figure OOO-5 is a UML sequence diagram to illustrate steps for creation and downstream use case for Radiopharmaceutical Radiation Dose report and CT dose report for the PET-CT system. The RRD is stored to an image archive and retrieved by the PET-CT scanner.

Figure OOO-6 is a UML sequence diagram to illustrate steps for creation and downstream use for radiopharmaceutical that is administered when the modality starts acquisition. The diagram illustrates that the dose report is reconciled with the image at later time by an image processing step.
