Method for operating radiation therapy device for treating tumors, involves carrying out irradiation of target area with therapy radiation and detection of current projection data of investigation object by X-ray unit alternately in time

摘要

The method involves performing continuous rotation of radiation sources (101, 102) and a detector (103) around an investigation object (106) during beam treatment, where the rotation of the radiation sources and the detector are in the same plane of rotation. The radiation sources are operated alternately in time, so that irradiation of a target area (111) with therapy radiation (105) i.e. X-ray radiation, and detection of current projection data of the investigation object are carried out by an X-ray unit alternately in time. An independent claim is also included for a radiation therapy device.
