![]() This P-RDSR object typically uses one or more RDSR objects as input. In addition to the above objects for recording the radiation details of an imaging study, the DICOM Standard has also defined an object for storing the results of an estimation of actual radiation dose to a patient. While these are good metrics to track and manage dose-related technique, using these scanner output metrics to estimate actual dose to a specific patient is complex and should be done in cooperation with a medical physicist. It should be noted that CTDIvol and DLP must be considered in the context of the phantom size (also recorded in the RDSR) used to calculated the metric. Support for these RDSR objects will appear in a product's DICOM Conformance Statement (DCS) document which is generally available on vendor websites. These templates have been developed in cooperation with medical physicists to incorporate common summary metrics such as CT Dose Index (CTDI), Dose Length Product (DLP), Dose Area Product (DAP), as well as detailed geometric and technique information that can be used to estimate the radiation dose to a patient. Radiopharmaceutical Radiation Dose Templates (PET, SPECT, Planar).Projection X-Ray Radiation Dose Templates (XA, RF, CR, DR & Mammography).The DICOM Standard has defined a set of Radiation Dose Structured Report (RDSR) data objects for recording and storing dose details in a DICOM study.
