Abstract
A detector assembly is provided that includes a semiconductor detector, a pinhole collimator, and a processing unit. The semiconductor detector has a first surface and a second surface opposed to each other. The first surface includes pixels, and the second surface includes a cathode electrode. The pinhole collimator includes an array of pinhole openings corresponding to the pixels. Each pinhole opening is associated with a single pixel of the semiconductor detector, and the area of each pinhole opening is smaller than a corresponding area of the corresponding pixel. The processing unit is operably coupled to the semiconductor detector and configured to identify detected events within virtual sub-pixels distributed along a length and width of the semiconductor detector. Each pixel includes a plurality of corresponding virtual sub-pixels (as interpreted by the processing unit), wherein absorbed photons are counted as events in a corresponding virtual sub-pixel.
