Abstract

A planar image detector for electromagnetic radiation has radiation-sensitive pixel elements arranged in a matrix that has a surface with active pixels for imaging and a surface with correction pixels, not exposed to the radiation for generating correction signals, and with contact surfaces next to the surfaces with the pixels. The surface with the correction pixels is arranged in a different plane from the surface with the active pixels and at one of the sides of the image detector with the contact surfaces of the active pixels.
