Abstract:
1. A method for generating an image of the radiation density of a source of photons located in an object, the method comprising: positioning first and second detectors in a spaced-apart relationship in a detector space; mechanically collimating photon emissions from the object to allow some mechanically-collimated photon emissions to enter the detector space while rejecting other photon emission from entering the detector space; utilizing the detectors to detect Computon scattering events between the dectors; utilizing the first and second detectors to detect non-Compton scattering events which interact with either the first detector or the second detector, but not with both detectors; and reconstructing an image from data containing detected Compton scattering events and detected non-Compton scattering events wherein the detected Compton scattering events provide angular information used in the step of reconstructing to improve image quality and wherein the angular information is based on a surface defined by energy deposited in the first detector and interaction positions in both of the detectors.
