  • Compton scatter imaging instrument
    Patent number: 6528795
    Abstract: A device for determining the photon energy E1 and direction cone angle of incident gamma ray includes a radiation detector for receiving an incident gamma ray having an unknown photon energy E1 and an unknown direction and for scattering the gamma ray with two Compton scattering interactions and a subsequent scattering or absorption interaction. The detector provides three outputs, each output corresponding to one of the Compton scattering and the subsequent scattering or absorption interactions, to a processor, which is programmed to calculate the photon energy E1 and direction cone angle of the incident gamma ray based on these outputs.
    Type: Grant
