Results or findings
Since all available transfers of dosimetric data are used in case of our custom-made DMS, it supports all imaging modalities of various generations used in our hospital.
List of all patients who underwent imaging or interventional procured is given after selecting the X-ray device used from a drop-down menu (Figure 1.). It is possible to see all previously performed imaging and/or interventional procedures for every patient (Figure 1.) as well as all phases of a particular procedure (Figure 2.). When generated by the X-ray unit, RDSR is easily accessible through DMS.
DMS calculates typical doses (medians) for the selected time period, X-ray unit and procedure and it presents them as a chart (Figure 3.). The chart simultaneously displays national DRLs as well as the most common value given in RP 180  for comparison with calculated typical dose.
After interventional procedure has been finished, DMS notifies the operator and the medical physicist via e-mail if one of the trigger levels has been exceeded, informing them of the need for a clinical follow-up of the patient who underwent that specific procedure. Trigger levels have been adopted from International Atomic Energy Agency (IAEA) SAFety in RADiological procedures (SAFRAD) criteria.
It also enables identification of patients undergoing multiple imaging or interventional procedures (Figure 4.).
It is also possible to see the selected X-ray unit workload (Figure 5.).
All data could be exported as an Excel table for further analysis when needed.
