The Effects of Ray Safe on Radiation Dose: An Analysis of Real-Time Dose Feedback on Absorbed Dose

Purpose: To determine the effect of the i3 Ray Safe system on the absorbed dose of physicians.

Materials and Methods:

To analyze the effectiveness that the Ray Safe system has on operator dose, the radiation dose of 4 senior physicians who regularly wore the Ray Safe dosimeters and who were expected to have consistent procedure volumes and case mix. Dosimetry reports of the 4 senior physicians were evaluated in the 2 years preceding the implementation of the Ray safe system, as well as 2 years following.

Results:

The findings of these reports demonstrate that the deep dose equivalent, shallow dose equivalent, and lens dose equivalents of each physician were reduced after the implementation of the Ray Safe Device. Physician #1 absorbed 13.5% less dose after the implementation of the ray safe device. Physician #2 experienced the smallest reduction in dose, with only a 3.5% reduction in dose. Physician # 3 experienced 7.09% reduction in dose. And Physician #4 experienced the most drastic change in dose with a 55.69% reduction in dose.

Conclusion:

Real time dose feedback reduces absorbed dose by making individuals who utilize it aware of their radiation exposure. This allows individuals who are dose conscious to take the measures necessary to mitigate the radiation they receive in real time.
