    摘要： A radiation detector device is provided that is capable of distinguishing between full charge collection (FCC) events and incomplete charge collection (ICC) events based upon a correlation value comparison algorithm that compares correlation values calculated for individually sensed radiation detection events with a calibrated FCC event correlation function. The calibrated FCC event correlation function serves as a reference curve utilized by a correlation value comparison algorithm to determine whether a sensed radiation detection event fits the profile of the FCC event correlation function within the noise tolerances of the radiation detector device. If the radiation detection event is determined to be an ICC event, then the spectrum for the ICC event is rejected and excluded from inclusion in the radiation detector device spectral analyses. The radiation detector device also can calculate a performance factor to determine the efficacy of distinguishing between FCC and ICC events.

    摘要： The preferred embodiments are directed to a high-energy detector that is electrically shielded using an anode, a cathode, and a conducting shield to substantially reduce or eliminate electrically unshielded area. The anode and the cathode are disposed at opposite ends of the detector and the conducting shield substantially surrounds at least a portion of the longitudinal surface of the detector. The conducting shield extends longitudinally to the anode end of the detector and substantially surrounds at least a portion of the detector. Signals read from one or more of the anode, cathode, and conducting shield can be used to determine the number of electrons that are liberated as a result of high-energy particles impinge on the detector. A correction technique can be implemented to correct for liberated electron that become trapped to improve the energy resolution of the high-energy detectors disclosed herein.

    摘要： An interwoven multi-aperture collimator for three-dimension radiation imaging applications is disclosed. The collimator comprises a collimator body including a plurality of apertures disposed in a two-dimensional grid. The collimator body is configured to absorb and collimate radiation beams emitted from a radiation source within a field of view of said collimator. The collimator body has a surface plane disposed closest to the radiation source. The two-dimensional grid is selectively divided into at least a first and a second group of apertures, respectively defining at least a first view and a second view of an object to be imaged. The first group of apertures is formed by interleaving or alternating rows of the grid, and the second group of apertures is formed by the rows of apertures adjacent to the rows of the first group. Each aperture in the first group is arranged in a first orientation angle with respect to the surface plane of said collimator body, and each aperture in the second group is arranged in a second orientation angle with respect to the surface plane of said collimator body such that the apertures of the first group are interwoven with the apertures of the second group.
