Abstract
The invention relates to a detector for an X-ray apparatus, which detector comprises a substrate (1) of amorphous or preferably crystalline silicon with an array (2) of sensor element (3) disposed thereon. Integrated electronic modules (4) having analog-digital converters disposed thereon are mounted on one edge (5) of the substrate (1) by flip-chip contacting or the like and are connected by way of signal leads (6) to the sensor elements. The modules (4) and/or the substrate can additionally comprise amplifiers and multiplexers for processing the sensor signals.
