摘要： The objective is to obtain a particle beam therapy system that can suppress the effect of a leakage dose. There are provided a scanning nozzle that irradiates in a predetermined direction a particle beam emitted from an accelerator; an irradiation control unit that controls operation of the irradiation nozzle in such a way that the particle beam of a predetermined dose is sequentially irradiated onto each of a plurality of spots set in a planar direction in an irradiation subject; and a control unit that on/off-controls emission of the particle beam from the accelerator. The irradiation control unit makes the irradiation nozzle scan in a diluting manner the particle beam onto a predetermined area in the irradiation subject, in a predetermined period after a time point when emission is switched from ON to OFF, or in a period from the time point when emission is switched from ON to OFF to a time point when the particle beam is cut off.
