[en] According to study, Gafchromic films (XR-QA2) were found to be practical to measure radiation irradiated area over the surface of a phantom. The obtained results seem to agree with other published dosimetric studies covering other types of dental cone beam computed tomography (DCBCT) scanners. The dosimetry results are important in order to document and audit radiation doses delivered to patients undergoing imaging studies using DCBCT. Patient dosimetry is a central part of the medical physics biannual quality assurance testing in DCBCT
