  • Patent number: 10835766
    Abstract: A particle beam treatment apparatus includes: a rotating gantry configured to axially rotate in a state where a bed fixed to a stationary system is disposed inside the rotating gantry and an irradiation port of a beam is fixed to a body of the rotating gantry; a tunnel structure configured to have at least a horizontal floor surface and have an internal space in which at least a part of the bed is accommodated; and a rotation supporter configured to cause the tunnel structure to be stationary in the stationary system independently of axis rotation of the rotating gantry by rotationally displacing the tunnel structure with respect to an inner side surface of the rotating gantry.

  • Patent number: 10799721
    Abstract: A particle beam therapy apparatus 10 includes: a particle beam irradiator 16 outputting a particle beam B; a movable supporting structure 21 supporting the particle beam irradiator 16; movable plates 37 disposed on a displacement trajectory of the particle beam irradiator 16, forming a substantially horizontal enveloping surface below a table 18 for placing an irradiation object 13, and including first and second floor members in at least one of the movable plates 37, the second floor member being larger in X-ray transmittance than the first floor member; an X-ray generator 27a provided in a non-collision area 31 where the X-ray generator 27a does not collide with any of the particle beam irradiator 16, the supporting structure 21, and the movable plates 37; and an X-ray detector 27b installed at a position where the X-ray detector 27b faces the X-ray generator 27a.

  • Patent number: 10525287
    Abstract: A particle beam treatment apparatus includes: a gantry configured to axially rotate in a state where an irradiation port for a beam is fixed to a body of the rotating gantry; a moving floor that is provided inside the gantry, is configured by annually connecting a plurality of plates with each other in a freely bendable manner, accommodates at least a part of a bed fixed from a stationary system, and rotates together with the gantry in a state of causing the irradiation port to penetrate the moving floor; a cable configured to be connected to a device fixed to the moving floor and be wired to outside of the gantry in a state of passing through the gantry; and an adjuster configured to adjust length of the cable wired inside the gantry when the gantry axially rotates.
