Embodiment Construction

[0038] figure 1 The inventive principle of one embodiment of the inventive device is shown. A high-energy beam 1 is generated by a radiation source 11 and modulated according to a treatment plan by a device 2 for modulating the beam, for example a multi-leaf collimator, and directed at a target volume 3 . Usually the target volume is the tumor of the patient 21 who is lying on the hospital bed 19 for treatment. According to the invention, between the device 2 for modulating the radiation and the patient 21, in the beam path 9 there is arranged a system for evaluating the high-energy modulated radiation 1 in terms of its shape and in the regions 16, 16', 16″(see image 3 ) aspects of the detection tool 8, so that the shape formation and intensity correction can be detected and monitored by the device 2 for modulating the radiation. If the modulation of ray 1 deviates from its theoretical value, it can be switched off or corrected.

Abstract

The invention relates to a device for performing and verifying therapeutic radiation. An x-ray (4) is arranged across from a target volume (3) of the beam source (11) for the high-energy beam (1) in such a way that the beams (1, 4) run in essentially opposite directions (5, 6). The invention also relates to a computer program and a control method for operating said device. The inventive device makes it possible to exactly verify areas (16, 16', 16') that are subjected to different levels of radiation, the entire anatomy of the target volume (3), and the surroundings thereof in addition to thecontour of the therapy beam (1). The x-ray (4) detects the anatomy and position of the patient (21) within the range of the target volume (3) before the high-energy beam (1) is applied and then detects the shape of the applied high-energy beam (1) and areas (16, 16', 16') that are subjected to different levels of radiation as well as at least one partial segment of the target volume (3) during theemission breaks of the high-energy beam (1). The detected datan is used for correcting the treatment plan.

Description

technical field [0001] The invention relates to a device for carrying out and verifying therapeutic irradiation with a radiation source of high-energy radiation and means for modulating the high-energy radiation on a gantry of an irradiation device, wherein for verification, depending on the target volume, In this way, the radiation source of the roentgen ray is arranged relative to the radiation source of the high-energy ray, so that the directions of the above two rays are basically opposite, and according to the direction of the roentgen ray, the tool for detecting the roentgen ray is arranged behind the target volume, and according to the direction of the high-energy ray The direction of the ray places the tool for detecting this ray in front of the target volume. The invention also relates to a computer program and a control method for operating the device. Background technique [0002] Such a device is disclosed in US5233990. In such a device it is provided that the ...
