The invention provides a charged particle therapy system capable of increasing the number of patients treated. An irradiation filed forming apparatus for irradiating a charged particle beam extracted from a charged particle beam generator to an irradiation target includes an RMW device. The RMW device comprises a housing and an RMW disposed within the housing. A rotary shaft of the RMW is rotatably mounted to the housing. The RMW device is detachably installed in an RMW holding member providied in a casing of the irradiation filed forming apparatus. The housing can be placed in contact with the RMW holding member, and hence positioning of the rotary shaft of the RMW to a predetermined position can be performed in a short time. This contributed to cutting a time required for treatment per patient and increasing the number of patients treated.
A charged particle therapy system including a charged particle beam generator for generating a charged particle beam and a charged particle beam irradiation apparatus,
A range modulation wheel device comprising a range modulation wheel having a rotary shaft and through which a charged particle beam passes, and a housing in which said range modulation wheel is disposed and rotatably mounted and configured to position said rotary shaft of the range modulation wheel in a charged particle beam irradiation apparatus by contact with a casing of said charged particle beam irradiation apparatus or a holding member provided in said casing for holding said range modulation wheel device.
