Abstract:
A radiation imager for converting incident radiation into an electrical signal corresponding to said incident radiation, the imager comprising:a scintillator having a first surface and a second surface;a photosensor array comprising a plurality of pixels optically coupled to said second surface of said scintillator; andan optical crosstalk attenuator optically coupled to said scintillator first surface, said crosstalk attenuator comprising at least an optical absorption material disposed so as to inhibit reflection of optical photons incident on said scintillator first surface back into said scintillator along crosstalk reflection paths, said crosstalk reflection paths being oriented such that photons passing thereon would be incident upon said photosensor array outside of a focal area spatially corresponding to the absorption point in said scintillator of said incident radiation.
