Abstract
A system for imaging a gamma source includes a pixelated Compton scattering layer, for Compton scattering of gamma photons emitted by the gamma source, and a non-pixelated full-energy detector for detecting at least a portion of Compton scattered gamma photons geometrically encoded by a coded aperture positioned between the pixelated Compton scattering layer and the full-energy detector at a distance from the pixelated Compton scattering layer. A method for imaging a gamma source includes (a) detecting coincidence events, each including Compton scattering in a pixelated Compton scattering layer, and transmission to a non-pixelated full-energy detector of a Compton scattered gamma photon transmitted through a coded aperture located at a distance from the pixelated Compton scattering layer, and (b) determining an image of the gamma source from the detection of the coincidence events.
