Abstract:
1. A flat-panel X-ray radiation detector, comprising: a scintillator layer applied to a substrate and comprising elongated needles made from a scintillator material forming the scintillator layer, and an actively readable pixel array comprising photodiodes, wherein the thickness of the scintillator layer is in the range of 900 μm 2500 μm, wherein each elongated needle forms an angle with respect to a plane of the pixel array, wherein the respective angle for different needles decreases with increasing distance from a center of the detector, wherein the substrate comprises a pre-formed non-planar surface on which the scintillator layer is formed, the pre-formed non-planar substrate surface defining a plurality of substrate surface sections forming a plurality of different angles with respect to the plane of the pixel array, wherein each needle extends from one of the substrate surface sections, and wherein the angle of each needle with respect to the plane of the pixel array is defined by the angle of the substrate surface section from which it extends.
