Log file‐based quality assurance method for respiratory gating system
Journal of Applied Clinical Medical Physics, EarlyView.Abstract Background As medical linear accelerator technology advances, enabling higher dose rate deliveries, hypofractionation regimens has increased. This necessitates respiratory gating systems that synchronize radiation delivery with tumor position, requiring simple rigorous quality assurance (QA) to ensure treatment accuracy and patient safety ...
