Abstract With the development of radiotherapy technology,China has entered the era of precision radiotherapy. Medical electronic linear accelerators quality control is very important. This guide provides guidance for domestic medical institutions to develop their own quality control methods. The scope covers mechanical performance,safety interlock,dosimetric performance,imaging performance,and other special techniques. The aim of this guide is to unify the quality control protocol from different institutions. Taking into account the different brand models of equipment,the reference values and test methods are not unique. The quality control guidelines are for reference only,and the reference values need to refer to the measurement results during machine acceptance. It is recommended that each accelerator should have at least one medical physicist. For daily QA items,the therapist or medical physicist is in charge of the work;for monthly and annual QA items,medical physicist completes the work. Those who participate in quality control must be certified and trained,and the measurement results should be reviewed and archived by senior medical physicists.
