Patent ID: 7332724

Claim:
A detector for sensing and acquiring radiation data, comprising: solid state crystals forming a matrix of pixels and having a radiation detection field for sensing radiation events; and an electronic module being attached to each said pixel for counting said radiation events for each said pixel, said electronic module further comprising: a threshold analyzer for analyzing said radiation events, said threshold analyzer identifying valid events by comparing an energy level associated with said radiation event to a predetermined threshold; and at least first and second counters for counting said valid events, said threshold analyzer comparing said energy level to first and second energy ranges that comprise energy levels that are different with respect to each other, said first counter counting said valid events having an energy level within said first energy range and said second counter counting said valid events having an energy level within said second energy range and at least one of said first and second counters counting using increments greater than one when a duration of said valid event is greater than a duration threshold.
