ABSTRACT:
A CT detector includes a plurality of metallized anodes with each metallized anode separated from another metallized anode by a gap. A direct conversion material is electrically coupled to the plurality of metallized anodes and has a charge sharing region in which an electrical charge generated by an x-ray impinging the direct conversion material is shared between at least two of the plurality of metallized anodes. An x-ray attenuating material is positioned to attenuate x-rays directed toward the charge sharing region.
