Systems and methods for improving position resolution of charge-sharing position sensitive detectors

摘要

An imaging system configured to provide improved position resolution is disclosed. The imaging system includes detector acquisition circuitry that is configured to acquire a plurality of rise-times and a plurality of amplitudes from a detector assembly that includes an array of one or more detector elements. The imaging system also includes position determining circuitry that is configured to determine a plurality of respective impact positions on each of the detector elements. The plurality of impact positions is based on at least the plurality of rise-times and the plurality of the amplitudes acquired by the detector acquisition circuitry.
