This study aims to compare the Peak Skin Dose (PSD) that patients obtain from fluoroscopy procedures. The study will show the differences between the PSD measured and calculated from a solid-state detector and the values the unit is displaying. Also, the study will compare PSD measurements from Patient Radiation Dose Monitoring and Tracking Systems (PRDMT). Numerous parameters need to be obtained to depict the PSD that a patient is receiving accurately. The PSD is crucial in assessing the potential biological effects of radiation.

The formalization used to derive the calculated PSD in this study has been established by Jones, A. K., & Pasciak, A. S. et al. All values were obtained through solid-state detector measurements. Measurements were acquired from various radiation generating equipment manufacturers and numerous Patient Radiation Dose Monitoring and Tracking Systems (PRDMT). The PRDMTs that data was obtained from were Imalogix, PEMNET, Radiometrics, and Dosewise. Parameters collected throughout the study were kept consistent for accurate PSD calculations.

Overall, of the units collected, the average PSD obtained from solid-state detector measurements was 1,175 milligray (mGy). Also, the calculated mean PSD from the displayed Air Kerma Rates (AKR) was 1,428 mGy. The results indicate an average 39.4 percent difference between the measured PSD and the PRDMT. Finally, results displayed a 23.1 percent difference between the displayed Air Kerma Rates (AKR) PSD versus the PRDMT.
