  • Systems for increasing the sensitivity of gamma-ray imagers
    Patent number: 8330114
    Abstract: Systems that increase the position resolution and granularity of double sided segmented semiconductor detectors are provided. These systems increase the imaging resolution capability of such detectors, either used as Compton cameras, or as position sensitive radiation detectors in imagers such as SPECT, PET, coded apertures, multi-pinhole imagers, or other spatial or temporal modulated imagers.
    Type: Grant
    Filed: January 12, 2012
    Date of Patent: December 11, 2012
    Assignee: Lawrence Livermore National Security, LLC
    Inventors: Lucian Mihailescu, Kai M. Vetter, Daniel H. Chivers
