Abstract
Detector systems for enhanced radiographic imaging incorporate Compton and PET imaging capabilities. The detector designs employ one or more layers of detector modules comprised of edge-on or face-on detectors, or a combination of edge-on and face-on detectors, which may employ structured detectors. The detectors implement tracking capabilities and operate in a non-coincidence or coincidence detection mode.
