X=Ray device with adjustable primary beam aperture

摘要

The x-ray device has a detector for the generation of image signals and a beam imaging system (11,12) which forms an image of the aperture (5) opening on an additional radiation-to-electrical transducer (10), to which is connected the evaluation electronics for forming electrical signals corresp. to the aperture opening. The beam from a light source passes via the primary beam aperture to reach the transducer. The light reflected from the primary beam aperture is detected by at least one light sensor.
