Characterization of GafChromic XR‐RV2 film and comparator strip using a flatbed scanner in reflection mode

Interventional cardiology procedures are an effective alternative for the reestablishment of correct sanguineous circulation in the heart. However, this kind of procedures exposes to the patients to a relatively high radiation doses. Usually, the surface peak skin dose is evaluated using a visual scale with a comparator strip, nevertheless, even if the comparator strip provides a simple and quick method for estimating the dose it has an uncertainty of ±25%. For this reason, a better evaluation method is needed. The objective of our project is to determine the surface peak skin dose of interventional cardiology procedures using GafChromic XR‐RV2 film together with a commercial flatbed scanner in reflection mode. Here we report a protocol to handle GafChromic XR‐RV2 film using a commercial flat bed scanner in reflection mode aiming at an uncertainty of ±3%.
