The setting area of the particle beam treatment system is reduced. A particle beam irradiation system according to one embodiment of the present disclosure is provided with: an accelerator which is provided on a ground surface and accelerates a charged particle beam; a transport device that transports the charged particle beam emitted from the accelerator; an irradiation device that irradiates an irradiation target with the charged particle beam conveyed by the conveyance device; the rack is arranged on the ground, and an irradiation device is installed on the rack. In addition, the rack is provided with a rotating body which enables the irradiation device to rotate around the irradiation object; and a support device that supports the rotating body from the ground surface at a position where the projection surface of the rotating body onto the ground surface and the projection surface of the accelerator or the transport device onto the ground surface overlap at least partially.
Description
technical field [0001] The present invention relates to a particle beam irradiation system and a particle beam irradiation facility. Background technique [0002] Radiation therapy is a treatment method in which radiation such as X-rays or particle beams is irradiated to the affected area. The most popular of devices used for radiation therapy are X-ray therapy devices. However, since the radiation dose of X-rays is greatest on the body surface and passes through the body while being attenuated, there is concern that it may affect normal tissues located before and after the tumor. Particle beams, on the other hand, have higher radiation dose distributions in the deeper part known as the Bragg curve. In particle radiation therapy, taking full advantage of the feature that no radiation dose is given to the part deeper than the high radiation dose distribution (Bragg peak), the Bragg peak is adjusted to the position of the affected part, and the radiation dose is increased in...
