Evaluation of current quality assurance (QA) system for volumetric modulated arc therapy (VMAT) by studying the impact of introduced errors
Introduction: Currently, patient specific dosimetric measurements on diode arrays such as Delta4® (ScandiDos AB) is a part of standard quality assurance (QA) for RapidArc® (RA) at Herlev University hospital. However, a standing issue is the interpretation of the results from dosimetric measurements into consequences in the delivered absorbed dose to the patient. Furthermore, measurements are time
