ABSTRACT:
A readout system is disclosed for use in conjunction with a radiation detector to obtain radiographic images. The readout system includes an event gating mechanism for receiving signals which are simultaneously generated at a plurality of locations within a radiation detector in response to a radiation event and an estimating mechanism for identifying the locus of the radiation event from the signals. In one illustrated embodiment the event gating mechanism further includes circuitry for receiving signals from a first and second set of lines defining a 2-dimensional coordinate grid within an area radiation detector.
