The invention relates to a device for performing and verifying therapeutic radiation. An x-ray beam ( 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 the contour of the therapy beam ( 1 ). The x-ray beam ( 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 the shape of the applied high-energy beam ( 1 ) is then detected 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 the emission breaks of the high-energy beam ( 1 ). The detected data is used for correcting the treatment plan.
