The rotating gantry treatment room irradiates target with Heavy ion beam from any angle by turning the irradiation nozzle. The X-ray imaging device is equiped for patient positioning, and it also works for respiratory-gated irradiation system.
The fixed beam treatment room, unlike the rotating gantry, irradiates target with Heavy ion beam using the fixed irradiation nozzle in the horizontal direction or the vertical direction. When the tumor is irradiated from various angles, the angle is set by rolling the robotic couch. In the same manner as the rotating gantry treatment room, the fixed beam treatment room also has X-ray imaging device, etc.
