Abstract:Dynamic multi-leaf grating collimator is the key core device of linear accelerator for precise radiotherapy, which could
implement conformal and intensity modulated therapy, and improve the therapeutic effect. In this paper, the development history
and technical status of multi-leaf grating collimator at home and abroad are introduced systematically, and also introduces and
compares the technical performance differences between domestic and imported products. In this paper, the key technologies for
the development of high performance multi-leaf grating collimator are summarized and analyzed. Finally, the development trend of
dynamic multi-leaf grating collimator is discussed and prospected.
