  • Parallel transverse field (PTF) tilted and collimated detectors
    Patent number: 9700269
    Abstract: A computed tomography (CT) detector apparatus to increase energy resolution at a high count rate includes a plurality of fixed photon-counting detector (PCD) modules arranged in a ring, each PCD module including two Parallel-Transverse-Field (PTF) PCDs that are tilted with respect to a normal direction to a circumferential direction of the ring. Each PTF PCD includes a rectangular semiconductor crystal having a first face and a second face, wherein the first face and the second face are parallel, a cathode side including a cathode electrode covering the first face, and an anode side including a plurality of anode pixels on the second face. Each PTF PCD includes a collimator attached to a predetermined region of the PTF PCD, wherein the collimator blocks incident the X-rays.

  • Side-electrodes for a Faraday cage on a photon-counting detector array
    Patent number: 9618633
    Abstract: A computed tomography (CT) detector apparatus includes a plurality of detectors arranged in a ring, each detector being arranged inside a Faraday cage having a plurality of voltage-biased side-electrodes arranged on a side surface of the Faraday cage. The detectors include photon-counting detectors (PCDs). A voltage applied to the voltage-biased side-electrodes decreases from the anode side of the PCD to the cathode side of the PCD.
