Patent ID: 8445856

Claim:
A multi-element X-ray detector, including a plate-type multi-element scintillator which transforms X-rays falling onto an external surface of the scintillator into visible light and a photodetector matrix which optically contacts with an emitting surface of the scintillator and transforms optical radiation emitted on the inner surface of the scintillator into an electrical signal; its main feature is that the above-mentioned multi-element scintillator combines a discrete set of hetero-phase luminescent elements positioned in cells of a grid made of X-ray absorbing and light reflecting metal with geometrical dimensions for spacing, cross-section and interconnection thickness for each particular luminescent element, and coincide with the actions of a photodetector matrix; a rear side of the aforesaid metal grid has a reflecting layer, while its front surface has a multi-element semiconductor matrix with element-to-element contact with a luminescent detector; these contacting elements are simultaneously excited by X-ray radiation with energy 30 to 140 keV.
