Abstract
An X-ray examination apparatus for generating an X-ray image of an object, wherein X-ray image generator includes a brightness control input, image processor coupled to the X-ray image generator in order to output a brightness control signal to the control input. The X-ray image generator is provided with an X-ray data output, the image processor is provided with an X-ray data input coupled to the X-ray data output, and the image processor is arranged as calculating system for calculating absorption properties of the object and for generating the brightness control signal in dependence on the absorption properties. Intelligent measuring field selection is now possible on the basis of calculating absorption properties of identifiable objects or parts of objects reproduced in the visible image. Image quality is improved because of brightness control based on more intelligently selected measuring fields.
