Gafchromic Dosimetry Films for Evaluation of Exposure on CT and IVR by Directional Dependences

Currently, it is imperative to establishing a useful method of dose measurement for computed tomography (CT) and interventional radiology (IVR). This study investigated the usefulness of high-resolution GAFCHROMIC XR Type R Film (GAF-R film) for measurement of exposure dose for CT and IVR based on directional dependence.
