Abstract: A radiation detector unit including an interposer configured to electrically connect a pixelated radiation sensor positioned on a front side of the interposer to an application-specific integrated circuit (ASIC) positioned on a back side of the interposer, where the interposer has at least one feature which equalizes the energy resolution (ER) response of edge and center pixel detectors of the pixelated radiation sensor within 10% of one another.

Abstract: A method of calibrating a pixelated radiation detector containing a plurality of pixel detectors electrically connected to a plurality of respective read-out channels of detector read-out circuitry includes determining a sensor material deadtime, τsensor, for each of the plurality of pixel detectors, and adjusting the respective read-out channel deadtime, τASIC, based on the determined sensor material deadtime, τsensor, of the respective one of the plurality of pixel detectors, such that a total deadtime, τtotal of each pixel detector including a sum of the respective sensor material deadtime, τsensor, and the respective read-out channel deadtime, τASIC, varies by less than ±5% from each other.

Abstract: A method of X-ray imaging includes determining energies of photons emitted by an X-ray source and attenuated by an object that are detected by an energy-discriminating radiation detector, generating photon count data by counting a number of detected photons in a plurality of energy bins of the energy-discriminating radiation detector that includes a first energy bin and an adjacent second energy bin, and generating an X-ray image of the object using the photon count data. Detected photons determined to have an energy within a gap region between a maximum energy threshold of the first energy bin and a minimum energy threshold of the second energy bin are not included in the photon count data used to generate the X-ray image of the object.
