Abstract:
1. A medical ion radiotherapy assembly comprising: an exit window for a particle beam, a patient support device that includes a patient support that is disposable in front of the exit window into an irradiation position suitable for irradiating a patient, and a diagnostic device that is operable to determine the position of a tumor to be irradiated, the diagnostic device including a radiation source and a diametrically opposed radiation detector which are secured to a common support arm; the support arm being operably supported in such a way that both an angular motion about a longitudinal axis defined by the particle beam and an orbital motion about an axis perpendicular to the longitudinal axis can be executed, the radiation source and the radiation detector being movable in space around the patient support that is in the irradiation position; and a control unit that controls the patient support device and the diagnostic device, the control unit being operable to control a position of the patient support device based on an output of the diagnostic device and control the diagnostic device into a position for verifying that the tumor is located in an isocenter of the particle beam based on the position of the patient support device.
