Abstract: Various embodiments include methods of compensating for signal loss due to depth-of-interaction (DOI) effects in radiation detectors, thereby improving detector efficiency. Various embodiments may include detecting the amplitude of a primary charge signal in a first pixel of an array of detector pixels in response to a photon interaction event, detecting the amplitude of a secondary charge signal in a second pixel of the array, where the amplitude of the secondary charge signal has an opposite polarity than the polarity of the primary charge signal, and generating a corrected photon energy measurement of the photon interaction event by applying a correction to the detected amplitude of the primary charge signal based on the detected amplitude of the secondary charge signal. Further embodiments include methods of improving detector efficiency by compensating for both depth-of-interaction (DOI) and charge sharing effects.

Abstract: An X-ray detector module of a multi-module X-ray detector array having a local processing unit configured to provide real-time control and computational capabilities at the x-ray detector module. In various embodiments, by providing these capabilities in the detector module itself, as opposed to a component located downstream of the detector module, there may be an immediate cost reduction, opportunities to include additional features, and performance improvement opportunities not otherwise practical to implement in conventional X-ray imaging systems.

Abstract: Various aspects include methods for compensating for the effects of charge sharing among pixelate detectors in X-ray detectors by applying a correspondence factor to counts of X-ray photons in energy bins to estimate incident X-ray photon energy bins. The correspondence factor may be determined by determining an incident X-ray photon energy spectrum, adjusting the incident X-ray photon energy spectrum to account for an energy resolution of the pixelated detector, generating a charge sharing model for the adjusted incident X-ray photon energy spectrum based on a percentage charge sharing parameter of the pixelated detector, applying the charge sharing model to energy bins of the pixelated detector to estimate counts in each of the energy bins, and determining the correspondence factor by comparing the estimated counts in each of the energy bins to counts in the energy bins that would be expected for the adjusting the incident X-ray photon energy spectrum.

Abstract: Various aspects include methods and devices for reducing the scanning time for an X-ray diffraction scanner system by increasing the count rate or efficiency of the energy discriminating X-ray detector. In a first embodiment, the count rate of the energy discriminating X-ray detector is increased by increasing the number of detectors counting X-ray scatter photon in particular energy bins by configuring individual pixel detectors within a 2-D X-ray detector array to count photons within specific energy bins. In a second embodiment, the gain of amplifier components in the detector processing circuitry is increased in order to increase the energy resolution of the detector. In a third embodiment, the individual pixel detectors within a 2-D X-ray detector array are configured to count photons within specific energy bins and the gain of amplifier components in the detector processing circuitry is increased in order to increase the energy resolution of the detector.

Abstract: Various aspects include methods of compensating for issues caused by charge sharing between pixels in pixel radiation detectors. Various aspects may include measuring radiation energy spectra with circuitry capable of registering detection events occurring simultaneous or coincident in two or more pixels, adjusting energy measurements of simultaneous-multi-pixel detection events by a charge sharing correction factor, and determining a corrected energy spectrum by adding the adjusted energy measurements of simultaneous-multi-pixel detection events to energy spectra of detection events occurring in single pixels. Adjusting energy measurements of simultaneous-multi-pixel detection events may include multiplying measured energies of simultaneous-multi-pixel detection events by a factor of one plus the charge sharing correction factor.
