  • Patent number: 8519338
    Abstract: An X-ray detection device including a scintillator configured to convert gamma rays or X-rays into optical radiation, an optical image intensifier configured to intensify the optical radiation to generate intensified optical radiation, an optical coupling system configured to guide the intensified optical radiation, and a solid state detector configured to detect the intensified optical radiation to generate an interaction image representing an X-ray energy emission and to perform photon counting based on data of the interaction image.

  • Patent number: 5825033
    Abstract: A CdZnTe detector array with pixel electrodes indium-bump-bonded to a multiplexer readout circuit. The pixel size is selected so as to minimize the effect of hole trapping while ensuring that all interacting electrons deposit their energy in a designated central pixel. The readout is carried out either when a gamma-ray interaction event occurs or at time intervals likely to produce no more than one event of photon interaction at any given pixel. The readout signal for each pixel is compared to a corresponding threshold signal to identify clusters of adjacent pixels having an above-threshold signal. Then, a central pixel is designated for each cluster, the signals from a predetermined number of pixels in and/or neighboring the cluster are added to produce a cumulative signal, and the cumulative signal is assigned to the designated central pixel. The cumulative signals so produced and the positions of corresponding central pixels are then processed to generate an image of the gamma-ray emitting source.
