Device for determining a deviation between an isocenter indicated by an arrangement of lasers radiation equipment and the actual isocenter radiation equipment

摘要

Device for determining a position indicated by an arrangement of lasers with several lasers (14, 16, 18,20) and / or location and / or orientation of laser radiation fields (40, 42, 65, 66) emitted by the lasers , quecomprende a laser detector with a detector plate device, which is arranged at least one laser detectorde (60) with a detector field extending at least in a direction perpendicular to lasuperficie plate detecting plate (72) for detecting a laser radiation emitted by the arrangement of lasers, a first rotation drive being provided, with which the detector plate (72) is rotatable about central sueje and a second rotation drive being provided, with the at least a laser detector (80) is rotatable about an axis of rotation extending parallel to the central axis of the detector plate (72) Yque comprises an evaluation device (30), which is made pa ra determined from the values ​​demedición detected by the at least one laser detector (80) the position indicated by the arrangement of lasers and / wave location and / or orientation of fields of laser radiation (40, 42, 65, 66) emitted by the lasers (14, 16, 18, 20).
