Abstract

A diagnostic radiography system has an X-ray generator for emitting an X-ray beam, a planar X-tray image converter with a sensor unit with photosensitive pixel elements that are arranged in a matrix and, arranged behind the sensor unit in the direction of radiation, a back-illumination which is formed by elements that are arranged in a matrix are connected to a control device. When the back-illumination is switched on, the output signal of the sensor unit is measured, and the elements of the back-illumination are triggered individually by the control device for homogenization in the sense of producing a uniform output signal.
