Traceability in medical X-ray imaging dosimetry

X-ray imaging is an important technique used in medicine however it’s use forms the largest component of exposure to artificial ionizing radiation. Consistent quantification of a patient’s exposure to radiation with calibrated dosimetry equipment is essential to comply with Council Directive and ensure patient safety. Currently, the procedures used by calibration laboratories, based on relevant standards and international protocols, do not fully consider the recent technical developments in X-ray imaging. This project will perform a critical assessment of conditions applied in calibrations and study the performance of different dosimeters. Updated measurement and calibration procedures will be proposed for inclusion into standards and protocols.
