Patent ID: 6993112

Claim:
A device for performing and verifying therapeutic irradiation, the device having a radiation source for a high-energy beam and means for modulating the high-energy beam on a gantry of an irradiation device, wherein, for verification, a radiation source of an X-ray beam is disposed on a side of a target volume opposite to the radiation source for the high-energy beam such that a direction of the X-ray beam is substantially opposite to a direction of the high-energy beam, wherein a medium for detecting the X-ray beam and for detecting the high-energy beam is disposed between the radiation source for the high-energy beam and the target volume, the medium being designed to detect regions of different radiation doses of the high-energy beam, the device also having a controller connected to the medium for detecting the high-energy and X-ray beams, to the modulating means for the high-energy beam, to a drive for adjusting a position of a patient table, and to the radiation sources for the X-ray and high-energy beams, wherein the controller can be loaded with a treatment plan to control the device, the device comprising: means for detecting an anatomy and a position of the patient in a region of the target volume via the X-ray beam by directing the X-ray beam onto the region from various directions before application of the high-energy beam; means for comparing the detected anatomy and position of the patient to the treatment plan and for correcting the patient position and/or treatment plan, if necessary; means for applying the high-energy beam from a radiation direction and for detecting a shape and area of various radiation doses thereof; means for detecting at least one partial region of the target volume including an immediate vicinity thereof using the X-ray beam during an irradiation pause of the high-energy beam; means for comparing an X-ray recording with a detected applied high-energy beam and for correcting the treatment plan, if necessary; means for iterative repetition until a process prescribed by the treatment plan is completed for said radiation direction; and means for repeatedly changing said radiation direction as prescribed by the treatment plan.
