The recommendations of AAPM TG 142 on IGRT are timely. In our institute, we established a comprehensive imaging QA program on a medical accelerator based on AAPM TG 142 and implemented it successfully. In this paper, we share our one-year experience and performance evaluation of an OBI capable linear accelerator, Novalis Tx, per TG 142 guidelines.HumansImage EnhancementRadiotherapy Planning, Computer-AssistedCalibrationParticle AcceleratorsQuality ControlRadiotherapy, Image-GuidedJournal article2019-10-04
