Abstract
A particle therapy system includes an accelerator 1 which generates a particle beam for extraction, an irradiation apparatus 21 which irradiates the particle beam to an irradiation target 26, a gantry 18 which rotates together with the irradiation apparatus 21, and an MRI apparatus 50 which rotates together with the gantry 18. The MRI apparatus 50 includes a magnetic circuit composed of an iron core 60 and a plurality of coils 61 serving as a magnetic flux source. The iron core 60 includes two oppositely disposed magnetic poles 63A and 63B, and a return yoke 64 for connecting the magnetic poles 63A and 63B. The magnetic poles 63A, 63B have cavities 65A, 65B. The particle beam passing through the cavity 65A is irradiated to the irradiation target 26.
