Method and apparatus for radiation detection

An imaging system for imaging an object has an x-ray source for emitting x-rays. A detection system has a plurality of position sensitive detector planes, and the object is located between the x-ray source and the detection system. A portion of the x-rays pass through said object and pass into said plurality of detector planes and are detected within the plurality of detector planes. A multi-channel readout system is coupled to the plurality of position sensitive detector planes. A display system is coupled to the multi-channel readout system, and the display system displays an image of said object. A portion of the x-rays passing into the plurality of detector planes undergoes at least one Compton scatter within the plurality of detection planes and is detected. A total or partial energy corresponding to each portion of the emitted x-rays is recorded by a multichannel readout system. The direction for the said detected x-ray is determined and the direction and total or partial energy corresponding to each detected x-ray is processed by a multi-channel readout system to generate said image.
