Abstract
An x-ray apparatus is provided which allows the diaphragm aperture and the diaphragm position to be precisely identified in a simple manner. For this purpose, a radiation imaging system is provided which produces an image of the aperture of the primary diaphragm on a radiation-electrical transducer, the radiation-electrical transducer on which the aperture is imaged being separate from the radiation detector on which the complete diagnostics image is produced. The radiation-electrical transducer is followed by evaluation electronics for forming electrical signals corresponding to the diaphragm aperture size and position.
