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.

A radiation detector unit includes an interposer, at least one radiation sensor bonded to a front side of an interposer, an application-specific integrated chip (ASIC) bonded to a backside of the interposer, a carrier board bonded to the backside of the interposer and located on a backside of the ASIC, and at least one flex cable assembly attached to a respective side of the carrier board.

A detector element circuit for a CT imaging system may include a plurality of sensors for detecting photons passing through an object and a first electronic component configured to determine an energy of photons detected by the plurality of sensors and generate photon count data, which may be a count of detected photons in one or more energy bins. The detector element circuit may further include a second electronic component configured to receive the photon count data from the first electronic component and is clocked at a first clock rate; a local memory storage configured to receive the photon count data from the second electronic component at the first clock rate and to output the photon count data at a second clock rate.

A cathode conductive strip can be attached to a semiconductor radiation sensor by using a double sided dual adhesive electrically conductive tape in a sensor assembly or a detector module to provide reliable electrical connection between the semiconductor radiation sensor and the cathode conductive strip. The double sided dual adhesive electrically conductive tape includes an electrically conductive backing with two different adhesion strength adhesives on both sides. The high adhesion strength side is bonded to the cathode electrode of the semiconductor radiation sensor. The lower adhesion strength side is bonded to the conductive face of the cathode conductive strip.
