    摘要： A detector module for a CT imaging system is provided. The detector module includes a sensor element to convert x-rays to electrical signals. The sensor element is coupled to a data acquisition system (DAS) via an interconnect system, the DAS comprised of an electronic substrate and an integrated circuit. The interconnect system couples the sensor element, electronic substrate, and integrated circuit by way of a contact pad interconnect together with a wire bond interconnect or an additional contact pad interconnect.

    摘要： A diagnostic imaging system includes an x-ray source that emits a beam of x-ray energy toward an object to be imaged and an energy discriminating (ED) detector that receives the x-ray energy emitted by the x-ray energy source. The ED detector includes a first layer having a first thickness, wherein the first layer comprises a semiconductor configurable to operate in at least an integrating mode and a second layer having a second thickness greater than the first thickness, and configured to receive x-rays that pass through the first layer. The system further includes a data acquisition system (DAS) operably connected to the ED detector and a computer that is operably connected to the DAS. The computer is programmed to identify saturated data in the second layer and substitute the saturated data with non-saturated data from a corresponding pixel in the first layer.

    摘要： A method for reconstructing image data from measured sinogram data acquired from a CT system is provided. The CT system is configured for industrial imaging. The method includes pre-processing the measured sinogram data. The pre-processing includes performing a beam hardening correction on the measured sinogram data and performing a detector point spread function (PSF) correction and a detector lag correction on the measured sinogram data. The pre-processed sinogram data is reconstructed to generate the image data.

    摘要： A radiation detector includes a semiconductor crystal having a first surface and a second surface opposite to the first surface, a first electrode electrically coupled with the first surface of the semiconductor crystal to allow current to flow between the first electrode and the crystal, and an insulating layer on the first surface and between the semiconductor crystal and the first electrode so as to create a partially transmissive electrical barrier between the first electrode and the crystal. The insulating layer has a thickness ranging from about 50 nanometers to about 500 nanometers.
