  • Depth sensing in CdZnTe pixel detectors
    Patent number: 7518118
    Abstract: Interaction depth of photons in a CdZnTe pixel detector is measured by configuring an ASIC connected to the detector to measure both positive polarity and negative polarity signal amplitudes and then measuring a core pixel having positive signal amplitude and hallow pixels having negative signal amplitude and surrounding the core pixel.
    Type: Grant
    Filed: February 26, 2008
    Date of Patent: April 14, 2009
    Assignee: California Institute of Technology
    Inventors: Fiona A. Harrison, Walter Cook
