用于使用单个像素进行电荷共享识别和校正的系统和方法
摘要：
提供了一种辐射检测器系统，其包括半导体检测器、多个像素化阳极和至少一个处理器。像素化阳极中的至少一个被配置成产生对应于由该像素化阳极收集的电荷的收集电荷信号，并且产生对应于由相邻阳极收集的电荷的非收集电荷信号。所述至少一个处理器包括其中存储有指令的有形和非暂时性存储器，所述指令被配置成指导所述至少一个处理器：确定收集电荷信号的收集值；确定非收集电荷信号的非收集值；确定非收集电荷信号的校准值；使用收集值和校准值确定由电荷共享事件产生的总电荷；并且如果总电荷超过预定值，则将电荷共享事件计数为单个事件。
摘要（英）：

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.
