Figure OOO-5. UML Sequence Diagram for Typical Workflow​

Figure OOO-6 is a UML sequence diagram to illustrate steps for creation and downstream use for radiopharmaceutical that is admin-​ istered 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.​

Identification​

The Radiopharmaceutical Radiation Dose (RRD) template provides a means to report the radiopharmaceutical identification number​ and the identification numbers of its components.​

A typical use case is that when a radio-pharmacist elutes a radionuclide from a generator into a vial. The radionuclide elution is given​ an identification number (Radionuclide Vial Identifier). The pharmacists then draws some radionuclide from the vial to compound with​ areagent(ReagentVialIdentifier)creatingamultidosevialofaradiopharmaceutical.Themultidosevialisgivenidentificationnumber​ (Radiopharmaceutical Lot Identifier). Individual doses are drawn from the multidose vial for administration to patients. Each of the​ doses is given an identification number (Radiopharmaceutical Identifier).​

A second use case is that when a patient is prescribed 2 MBq of an oral radiopharmaceutical. The radio-pharmacist dispenses two​ 1MBqcapsules.Eachcapsulemayhavedifferentlotnumber(RadiopharmaceuticalLotIdentifier).Thetwocapsulesareadministered​ at the same time as one dose (Radiopharmaceutical Identifier). The report may contain two Radiopharmaceutical Lot Identifiers one​ for each capsule and one radiopharmaceutical identifier for the dose.​

Figure OOO-7 is a diagram the displays the hierarchical relationship between the radiopharmaceutical dispense unit identifier, radio-​ pharmaceutical lot identifier, reagent vial identifier and the radionuclide vial identifier.​

PPP Examples of Communication of Display​

Parameters (Informative)​

PPP.1 The Relationship Between AE and Display System​

The Display System SCU and the Display System SCP are peer DICOM Communication of Display Parameters management applic-​ ation entities. The application entity of the Display System SCP supports one or more display subsystems.​

Display System SCU and the SCP establish an association by using the association services of the OSI upper layer service.​

While the association is being established, each of application entity negotiates the supported SOP classes.​

PPP.2 Examples of Message Sequencing​

This section provides an examples of message sequencing when using the Display System SOP Class. This section is not intended​ to provide an exhaustive set of use cases but rather an informative example. There are other valid message sequences that could​ be used to obtain an equivalent outcome.​

QC Management Station: Manages display systems status and Configurations. This works as an SCU.​

Display System A and B: Have display devices. Each display device may be other display vendors'. These work as SCPs.​ Generation and notification of change events are out of a scope of DICOM.​
