Abstract
For a uniform image quality of digital X-ray records, a solid-state detector is provided. The detector includes light-sensitive pixel elements arranged in an active matrix, and a reset light source arranged behind them in the radiation direction of X-ray radiation, with the reset light source being in the form of an arrangement with light-emitting diodes and with the light-emitting diodes being designed such that can be driven individually and their intensity can be controlled individually. At least one of a failed and malfunctioning light-emitting diode is detectable. The intensities of the serviceable light-emitting diodes are driven and controlled in the event of a failure or a malfunction of at least one light-emitting diode in such a manner that the intensity and/or the homogeneity of the reset light source remains the same.
