  • Solid state X-ray detector with improved spatial resolution
    Publication number: 20050249331
    Abstract: A monolithic detector uses a grid to block x-rays from inter-pixel regions such as are believed to cause electrical noise in the pixel signals.
    Type: Application

    Publication date: November 10, 2005
    Inventors: James Wear, Robert Washenko
  • Solid-state X-ray detector with support mounted steering electrodes
    Publication number: 20050247880
    Abstract: Steering electrodes are used to improve the uniformity and efficiency of solid-state semiconductor x-ray detectors. The steering electrodes are insulated from the semiconductor material so as to prevent surface current flows that degrade the signal to noise ratio of the detected signal.

  • Monolithic X-ray detector with staggered detection areas
    Publication number: 20050247882
    Abstract: A monolithic solid-state detector using a staggered arrangement of pixels in multiple rows improves spatial resolution without requiring reduction in pixel size. Parallelogram shapes of CZT monolith allow tiling in one dimension without inefficient zones between monoliths. A scanning device using linear array of detectors with non-rectangular shape and staggered rows of detection elements such that no dead zones occur within a scan field.

  • Multi-energy x-ray machine with reduced tube loading
    Patent number: 6246747
    Abstract: An energy discriminator, for distinguishing between high and low x-ray energies in a energy sensitive x-ray machine divides high energies into asymmetric regions. The flux rates in each of the asymmetric regions being used to locate the high-energy region in the appropriate high-energy location even in regions of spectral monotonicity. Because two clearly defined spectral peaks need not be present for accurate location of spectral regions in the output of the detector, less filtering and lower tube loading is required.
