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.

Particle beam therapy apparatus

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.
