Abstract

An X-ray detector includes an X-ray converter for conversion of X-ray radiation to light, and a photodiode sensor with an arrangement of two or more photodiode elements for detection of the light produced by the X-ray radiation in the X-ray converter. A nonlinearly absorbent filter is located between the X-ray converter and the photodiode sensor.
