Rotating irradiation therapy apparatus
First Claim
1. A rotating irradiation therapy apparatus having a charged particle beam irradiation device, a beam transport device for introducing a charged particle beam to the irradiation device, a rotating body on which the beam transport device and the irradiation device are mounted, and rotating body support devices with freely-rotating rollers that come into contact with a circular member contained in the rotating body to support the rotating body, the rotating irradiation therapy apparatus comprising:
- a first circular member which comes into contact with the rollers of the rotating body support devices at one axial end of the rotating body;
a second circular member which comes into contact with the rollers of the rotating body support devices at the other axial end of the rotating body; and
an intermediate circular member which comes into contact with the rollers of at least one of the rotating body support devices at a different axial position of the rotating body between the first circular member and the second circular member.

Abstract
A rotating irradiation therapy apparatus used for particle beam therapy includes a rotating gantry equipped with a charged particle beam irradiation device beam transport devices for guiding a charged particle beam to the irradiation device and a roller in contact with a ring member included in the rotating gantry and supporting the gantry. A front ring is disposed in contact with the roller of a rotating body support device at one end in the axial direction of the rotating gantry, and a rear ring is disposed in contact with the roller at the other end in the axial direction of the rotating gantry. At least one intermediate ring is disposed in a position different in the axial direction of the gantry between the front and rear rings and in contact with the roller.
