Abstract
A radiation detector system is provided including a semiconductor detector, plural pixelated anodes, and at least one processor. At least one of the pixelated anodes is configured to generate a collected charge signal corresponding to charge collected by the pixelated anode and to generate a non-collected charge signal corresponding to charge collected by an adjacent anode. The at least one processor includes a tangible and non-transitory memory having stored thereon instructions configured to direct the at least one processor to determine a collected value for the collected charge signal, to determine a non-collected value for the non-collected charge signal, determine a calibrated value for the non-collected charge signal, determine a total charge produced by a charge sharing event using the collected value and the calibrated value, and count the charge sharing event as a single event if the total charge exceeds a predetermined value.
