Abstract
X-ray diagnostic installation has a high-voltage generator for an X-ray tube for generating an X-ray beam, an X-ray image converter that has a scintillator layer and a semiconductor layer with light-sensitive pixel elements arranged in a matrix, and a combined back light/dose measuring unit arranged therebehind in the beam direction that is formed by an array of light-emitting diodes arranged in a matrix, as backside illumination, and light-sensitive sensors that acquire the X-ray dose, as sensors, and a measurement transducer for the control of the high-voltage generator connected thereto. Light waveguides are arranged in front of the light-sensitive sensors and between the light-emitting diodes, these light waveguides conducting the light that proceeds from the X-ray image converter during the irradiation and that is incident onto the combined back light/dose measuring unit onto the light-sensitive sensors.
