【Abstract】 The basic principle and characteristic of irradiation in heavy ion radiotherapy are introduced. Based on the basic principle and characteristic of irradiation in heavy ion radiotherapy, two magnetic scan methods for creating uniform irradiation field--the spot scan and the raster scan, are compared briefly. The parameter requests to the magnetic scanning system of the heavy ion radiotherapy facility planned in IMP(Institute of Modern Physics) are presented.更多还原
