Particle beam irradiation system
First Claim
1. A particle beam irradiation system comprising:
- a particle beam irradiation apparatus having a particle beam irradiator for irradiating an affected area of a patient with a particle beam from one direction, said particle beam irradiation apparatus being free of a gantry structure, said particle beam irradiator being housed in a chamber;
a CT scanner installed in said chamber, for positionally confirming said affected area of the patient;
a drive unit operable to move said patient between a detection zone of said CT scanner and an irradiation zone of said particle beam irradiation apparatus;
a patient fixing device for fixing said patient in position, said patient fixing device being mounted on said drive unit, and being rotatable about the craniocaudal axis of said patient; and
a housing unit having a structure carrying said drive unit with said patient fixing device mounted and said CT scanner, said housing unit being rotatable in said chamber about an axis perpendicular to a plane including a direction in which the particle beam is applied by said particle beam irradiation apparatus and a direction in which said drive unit moves.

Abstract
A particle beam irradiation system includes a particle beam irradiation apparatus, which is free of a gantry structure, having a particle beam irradiator for irradiating an affected area of a patient with a particle beam, the particle beam irradiator being housed in a chamber, a CT scanner installed in the chamber, for positionally confirming the affected area of the patient, a drive unit for moving the patient from a detection range to an irradiation range, a patient fixing device for fixing the patient in position, the device being mounted on the drive unit for rotation, and a housing unit having a structure housing the drive unit with the patient fixing device mounted and the CT scanner, the housing unit being rotatable about an axis perpendicular to a plane including a direction in which the particle beam is applied and a direction in which the drive unit moves.
