Comparing log file to measurement-based patient-specific quality assurance

Physical and Engineering Sciences in Medicine, 2022
Abstract Recent technological advances have allowed the possibility of performing patient-specific quality assurance (QA) without time-intensive measurements. The objectives of this study are to: 1) compare how well the log file-based Mobius QA system agrees with measurement-based QA methods (ArcCHECK and portal dosimetry, PD) in passing and ...
