PROBLEM TO BE SOLVED: To provide a simulation device and simulation method for charged particle beam amount, which allow early determination of a dose distribution of charged particle beam with a reduced load on arithmetic processing while suppressing the deterioration of accuracy.;SOLUTION: The simulation device 3 includes: an input unit 31 which receives input of simulation data including material information of an irradiation object X and irradiation information of proton beam B; and an arithmetic unit 33 which determines a dose distribution of the proton beam B within the irradiation object X based on the simulation data received by the input unit 31 and a dose distribution kernel. The arithmetic unit 33 forms a Surface Map from the proton beam B assumed to reach the body surface, breaks down the Surface Map to break down the proton beam B into a plurality of beamlets Ba, and determines the dose distribution of the proton beam B within the irradiation body X based on the simulation data received by the input unit 31 and the plurality of beamlets Ba.;COPYRIGHT: (C)2012,JPO&INPIT
