Abstract
An indirect x-ray imager including one or more semi-transparent layers that reduce lateral spreading of light produced by the scintillator layer. The semi-transparent layers may be one or more layers above and/or below the scintillator, which the light generated by the scintillator goes through prior to being received by an array of photosensors. The semi-transparent layers may have a light transparency that is proportional to the pixel pitch of the photosensor, and/or proportional to a thickness of the layers. The semi-transparent layers have a light transparency that allows a high percent of the light to be received across the thickness of the layer, but restrains most of the light from being received across a lateral distance of more than one pixel pitch. Other embodiments are also described and claimed.
