Beam irradiation apparatus , beam irradiation control method and heavy particle beam therapy system

摘要

Topic Until recently, as quite it can form in the thin beam diameter where it is not, beam diameter is controlled in high accuracy, furthermore beam range and the beam lighting device which can control also the beam track and the beam lighting control method where it can control the range of the radiation field in the lighting object at high accuracy are offered.SolutionsWhile the beam maintaining convergent angle, the evacuation which becomes the traffic channel of the beam which is removed from the accelerator vis-a-vis the transport pipe which is done and the lighting object which exists in the atmosphere, in order incidence to do, with as 4 polar electromagnets and the lighting object of the beam and it is provided distance variably, making the beam pass, it decreased beam energy and the movable range shifter control beam diameter of 1 or more which where beam range is controlled it consisted of, controlled beam diameter and beam range, targeting lighting it constituted of the beam lighting device which features that the beam is made to irradiate.
