Abstract

A detector includes a photon-counting detector (PCD) layer and a cathode layer arranged adjacent to the PCD layer. The detector further includes a plurality of pixilated anodes arranged adjacent to the photon-counting detecting layer on a side opposite to the cathode layer. The detector also includes a plurality of collimator segments arranged above the cathode layer so as to block a portion of X-ray photons emitted from an X-ray source from reaching the anodes, where each collimator segment is arranged above a portion of at least one anode.
