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.
