Abstract

There is provided a rotating irradiation apparatus that can secure as large an access floor as possible, reduce noise during the formation of an access floor, and stably operate with a simple structure. The rotating irradiation apparatus includes an irradiation devicethat irradiates a charged particle beam, a frameon which the irradiation device is mounted and which rotates the irradiation device so that a patient lying on a treatment tablefixed to a stationary floor surface is irradiated with the charged particle beam, a ringthat is rotatably held on an inner periphery of the frame, an opening/closing-type floorwhich is provided inside the ring and of which a portion through which the irradiation device passes is openable and closable, and drive meansthat reversely rotates the ring in synchronization with the rotation of the irradiation device so as to maintain the opening/closing-type floor horizontal.
