Patent ID: 7283608

Claim:
An X-ray imaging system comprising: an X-ray source for generating X-rays; and an X-ray detector configured to provide X-ray intensity variation information relating to the X-rays and corresponding to each of a plurality of detector cells of the X-ray detector, wherein a plurality of detecting layers comprise at least one spatial resolution layer and at least one X-ray absorption layer, the at least one spatial resolution layer absorbing substantially less of the X-rays than the at least one X-ray absorption layer and wherein the at least one spatial resolution layer is positioned between an object to be imaged and the at least one X-ray absorption layer, wherein the at least one spatial resolution layer is located within the detector cells, wherein the at least one spatial resolution layer is sub-pixelated, wherein the at least one spatial resolution layer is configured to obtain X-ray detection mapping information based on a sub-pixelation of the at least one spatial resolution layer, and wherein the X-ray imaging system is configured to associate the X-ray detection mapping information to sub-divide a signal detected by the at least one X-ray absorption layer.
