Abstract:
An X-ray detector for converting X-rays into electric charges, comprising:a photosensor arrangement having photosensitive elements separated from one another such that spaces are formed between the photosensitive elements; a scintillator arrangement arranged on a first side of the photosensor arrangement, at least one additional layer arranged adjacent the scintillator arrangement to form a transition between the scintillator arrangement and the at least one additional layer enabling the reflection of light, and a retroreflector arrangement arranged on a second side of the photosensor arrangement opposite from the first side, whereby light passing through the spaces between the photosensitive elements is reflected by the reflector arrangement toward the scintillator arrangement and the at least one additional layer and then reflected at the transition between the scintillator arrangement and the at least one additional layer back toward the photosensitive elements.
