Abstract
A radiation detector system is provided including a semiconductor detector, plural pixelated anodes, and at least one processor. The plural pixelated anodes are disposed on a surface of the detector. At least one of the pixelated anodes is configured to generate a collected charge signal corresponding to a charge collected by the pixelated anode and to generate a non-collected charge signal corresponding to a charge collected by an adjacent anode to the pixelated anode. The at least one processor is configured to determine a collected value for the collected charge signal in the pixelated anode; determine a non-collected value for the non-collected charge signal in the pixelated anode corresponding to the charge collected by the adjacent anode; use the non-collected value for the non-collected charge signal to determine a sub-pixel location for the adjacent anode; and use the collected value to count a single event in the pixelated anode.
