Medical charged particle irradiation apparatus
First Claim
1. A charged particle beam irradiating method, comprising the steps of:
- arranging a beam transport device for transporting said charged particle beam, an irradiation field forming device for forming an irradiation field for said charged particle beam transported by said beam transport device, a rotating body provided with said beam transport device and said irradiation field forming device and being rotatable about an axis of rotation, said irradiation field forming device being eccentrically arranged to the axis of rotation such that an axis of irradiation thereof passes a position different from the axis of rotation, and a bed for supporting an irradiation target being rotatably suspended from and supported by said irradiation field forming device and being arranged on an opposite side of said beam transport device with respect to a plane which contains the axis of rotation and being substantially perpendicular to the axis of irradiation;
rotating said rotating body such that the axis of irradiation of said irradiation field forming device is matched with a setting irradiation direction of said charged particle beam to said irradiation target;
driving said bed to adjust inclination of said bed; and
irradiating said charged particle beam emitted from said irradiation field forming device to said irradiation target.

Abstract
A medical charged particle irradiation apparatus capable of irradiation from upward and horizontal directions and performing a preparing/ascertaining work without any separate device such as a moving capsule or the like comprising a patient'"'"'s bed, on which a patient lies, a transport equipment for injecting and transporting charged particle beams toward the patient'"'"'s bed, an irradiation field forming device for forming an irradiation field for the beams transported by the transport equipment, and a gantry provided to be rotatable about an axis of rotation, and wherein the irradiation field forming device is eccentrically arranged such that an axis of irradiation passes a position different from the axis of rotation, and the patient'"'"'s bed is arranged on an opposite side of the transport equipment to a plane, which contains the axis of rotation and is substantially perpendicular to the axis of irradiation.
