Physical dosimetry of volumetric modulated arc therapy (VMAT) using EPID and 2D array for quality assurance

ConclusionsSpecific QA of VMAT patient (using EPID or 2D array) display great possibility to spare time and to verify individual IMRT fields. 3%/3 mm is the most appropriate of gamma criteria (DD/DTA) for VMAT plans quality assurance. Control charts are a beneficial method for verification assessment for patient specific quality control.
