ABSTRACT:
A solid-state radiation detector includes an active pixel matrix, which is arranged at one side with a scintillator layer, which emits light that can be converted into electrical charge by the pixel matrix depending on incident radiation, in particular X-ray radiation, and which is arranged on a carrier at the other side. At least one layer that at least partly absorbs the light that originates from the scintillator layer and has penetrated into the carrier is provided at the carrier.
