Rotating irradiation apparatus
First Claim
1. A rotating irradiation apparatus comprising:
- a rotatable body provided with an irradiation device and a beam delivery device, said irradiation device emitting an ion beam, said beam delivery device delivering said ion beam into said irradiation device;
a first rotating body support device including a plurality of rotatable rollers for supporting one end portion of said rotatable body, said rotatable rollers being in contact with said rotatable body;
a second rotating body support device including a plurality of rotatable rollers for supporting the other end portion of said rotatable body, said rotatable rollers being in contact with said rotatable body;
a drive device for rotating one or more of said plurality of rollers in said first rotating body support device; and
a plurality of thrust support devices for limiting movement of said rotatable body in the direction of the rotational axis of said rotatable body;
wherein said first rotating body support device or both said first and second rotating body support devices are movable in said direction of said rotational axis.

Abstract
A rotating irradiation apparatus includes a rotating gantry 3 including a front ring 19 and a rear ring 20 and is provided with a beam delivery device 11 and an irradiation device 4. The beam delivery device 11 delivers an ion beam used for particle radiotherapy. Radial support devices 61A and 61B support the front ring 19 and radial support devices 61A and 61B support the rear ring 20. Each radial support device includes a linear guide 41, an upper support structure disposed above the linear guide 41, and a lower support structure disposed below the linear guide 41. The upper support structure is movably mounted on the lower support structure and is movable in the direction of the rotational axis of the rotating gantry 3.

25. A rotating irradiation apparatus comprising:
-
a rotatable body which has first and second annular members, the rotatable body rotates about a rotational axis;
an irradiation device provided within the rotatable body and which irradiates an ion beam;
a beam delivery device which delivers the ion beam to the irradiation device;
a first rotating body support device, including a plurality of rollers, which supports the first annular member, the rollers being in contact with the first annular member;
a second rotating body support device, including a plurality of rollers, which supports the second annular member, the rollers being in contact with the second annular member;
a drive device which rotates one or more of the plurality of rollers in the first rotating body support device; and
a plurality of thrust support devices for limiting movement of the rotatable body in only the direction of the rotational axis of the rotatable body, wherein the first rotating body support device or both the first and second rotating body support devices are movable in only the direction of the rotational axis, and the plurality of thrust support devices are separately provided from one or more of the plurality of rollers driven by the drive device. - View Dependent Claims (26, 27, 28, 29)

30. A rotating irradiation apparatus comprising:
-
a rotatable body which has first and second annular members, the rotatable body rotates about a rotational axis;
an irradiation device provided within the rotatable body and which irradiates an ion beam;
a beam delivery device which delivers the ion beam to the irradiation device;
a first rotating body support device, including a plurality of rollers, which supports the first annular member, the rollers being in contact with the first annular member;
a second rotating body support device, including a plurality of rollers, which supports the second annular member, the rollers being in contact with the second annular member;
a drive device which rotates one or more of the plurality of rollers in the first rotating body support device; and
wherein a force of skewing resulting from misalignment of a roller with respect to the rotating body is compensated for by permitting the first or second rotating body support devices to be movable in the direction of the rotational axis. - View Dependent Claims (31, 32, 33, 34, 35, 36)
