This report is the final outcome and summary of the work of the EURADOS WG12, Sub-Group (SG) 3: Technical aspects on DAP calibration and CT calibration. Management of patient dose in the high dose procedures of interventional radiology (IR) and computed tomography (CT) requires regular and accurate determinations of the practical dose quantities, which are relevant for the basis of actual patient dose determination and setting of the diagnostic reference levels (DRL) or trigger levels for skin dose alert in IR. The accurate measurement of the required quantities is based on accurate calibrations. The complexity of IR procedures and the rapid development of the CT scanners have made an accurate dose measurement a challenging task. In this report, the recent dosimetric problems as well as the development to cope with these problems are reviewed. Further, the results of comparisons of KAP (DAP) meter calibrations, both at the level of standard dosimetry laboratories and at hospitals in field conditions, are briefly summarized. Based on the review and the comparison of calibrations, a few conclusions and recommendations are given. |
