Abstract:
1. An irradiation apparatus for radiating a radiation beam transported from a particle accelerator onto a location to be irradiated that is positioned on an irradiation table, said apparatus comprising: a beam interruption part for interrupting said radiation beam; a position control part for controlling a position of said irradiation table such that said radiation beam is radiated onto an entire surface of a target in a plurality of irradiation zones including an overlapping zone formed by a plurality of radiations of said radiation beam; and a multileaf collimator control part for controlling said radiation beam to provide a slope to a dose distribution in said overlapping zone of said irradiation zones, respectively, such that the dose distribution is made flat over the entire surface of said target including said overlapping zone by the plurality of radiations of said radiation beam.
