Data Sources in Medical Imaging

The DICOM standard also provides definitions for files that do not contain image information, but instead only provide summary data. For example, the radiation dose indices and associated technique parameters associated with a study are stored in the Radiation Dose Structured Report (RDSR). To a medical physicist, RDSR objects are of great interest, as this information can be used to track or monitor the radiation dose indices in a clinic. An organization promoting health care information system integration, Integrating the Healthcare Enterprise (IHE), provides a technical framework that can be used to set up systems to aggregate RDSR through the Radiation Exposure Monitoring (REM) profile[7].
Integrating with other Systems

3I Data from examination/test sent for interpreting and records made on the relevant CIS (RIS and PACS for radiology, LIMS for pathology). The results need to be sent and stored so that they can be interpreted easily in a variety of ways by specialist processing workstations or trained staff. New data that can be automatically added in the Radiology department is the dose information by utilising the IHE profile radiation exposure monitoring (REM).

Dosimetry records documenting radiation exposure received before or after employment as a medical radiation worker were obtained for 4,482 workers from four additional sources: DOE Radiation Exposure Monitoring System (REMS) (U.S. Department of Energy (DOE) 2021) including other historic DOE radiation exposure data not included in DOE REMS (n = 734); the Nuclear Regulatory Commission Radiation Exposure Information and Reporting System (REIRS) (n = 1,999) (USNRC 2019); the U.S. Navy Dosimetry System (n = 2,110) (NDC 2021); and the Nuclear Test Personnel Review Program (DTRA 2020; Boice, Cohen et al. 2020). All organ/tissue-specific doses from each source were added together to obtain the total organ/tissue-specific external dose received by each worker for each calendar year, following the procedures outlined in Boice et al. (2006) and Ellis et al. (2018).

Most radiation exposures received by nuclear power plant workers were from penetrating external gamma radiation with only a negligible contribution coming from neutrons or intakes of radioactive material (Bouville et al. 2015; Dauer et al. 2018; NCRP 2018a). Annual personal dose equivalents, Hp(10), were available from the REIRS and Landauer files. Radiation doses from all places of employment were sought by linking the study roster to the Radiation Exposure Monitoring System (REMS) maintained by the U.S. Department of Energy (DOE) (DOE 2021), other DOE dosimetry databases, and U.S. military service dosimetry databases. All doses were combined to create annual dose estimates for each worker following methods previously described (Boice et al. 2006; Ellis, Boice et al. 2018). Overall, the mean cumulative Hp(10) was estimated as 19.5 mSv for all 425,713 workers eligible for the study, 52.6 mSv for the study cohort of 135,193 workers, and 61.3 mSv for the 115,288 workers with cumulative doses >10 mSv (maximum 1.32 Sv).
Mortality among U.S. military participants at eight aboveground nuclear weapons test series

To obtain as complete an assessment of all occupational radiation exposure as possible, both before and after participation as a nuclear weapons test participant, the rosters of atomic veterans were matched against dosimetry registries maintained by the military services (Navy, Army, and Air Force), the U.S. Nuclear Regulatory Commission’s Radiation Exposure Information Reporting System (REIRS), the U.S. Department of Energy’s Radiation Exposure Monitoring System (REMS), and a private dosimetry service (Landauer, Inc.) (Boice et al. 2006; Hagemeyer et al. 2018; Dauer et al. 2018). Linkage variables included the military service number, social security number, and/or name and date of birth. The dosimetry data bases were comprehensive; e.g., the NRC REIRS data files are of high quality by law and the Naval Dosimetry Center validated each match from original dosimetry records. Matches were primarily by social security number, with name and/or DOB as confirmation of a valid match. This supplemental dosimetry linkage provided additional radiation exposure information for just over 6000 of the veterans in the Eight Series Study.
