  • Publication number: 20070064866
    Abstract: A method for obtaining data includes scanning an object with radiation to collect projection data using an imaging system having a detector array with detector cells and a post-patient collimator, wherein the post-patient collimator has plates having non-uniform thicknesses. The method further includes applying a correction to the projection data to shift an effective center of at least some of the detector cells to compensate for the non-uniform thicknesses of the collimator plates.

  • Publication number: 20060289777
    Abstract: In accordance with an implementation of the present technique, a detector is disclosed. The detector includes a photodetector array and a substrate layer. The photodetector array includes a plurality of photodiodes and a structure of trenches or diffusions grids that electrically isolate each photodiode of the plurality of photodiodes. The plurality of photodiodes and the structure of trenches or deep diffusions grids are disposed on a first surface of the photodetector array and a second surface opposite the first surface is bonded to a substrate layer. The substrate layer is typically made of the same semiconductor material as the photodetector array but heavily doped and conductive to provide cathode contact to the photodetector array in addition to mechanical support.

  • Patent number: 7074056
    Abstract: A connector cap assembly mechanically and electrically couples to the connector back shell that has connector contacts. A boot housing is formed of an electrically charged dissipative material. The housing is sized to receive the connector therein. The boot housing comprises a floor that contacts the connector contacts. A retainer is positioned on the housing and retains a ground wire in contact with the housing.

  • Publication number: 20060071173
    Abstract: A computerized tomography imaging scanner module includes a plurality of scintillators, a plurality of back-illuminated photodiodes optically coupled with the scintillators, a multi-layer substrate having a plurality of substrate electrical conductors to which the photodiodes are electrically coupled, wherein each of the plurality of substrate conductors is connected to a different one of the back-illuminated photodiodes, and a flexible cable having a plurality of flex electrical conductors to which the substrate is electrically coupled, wherein each of the plurality of flex electrical conductors is connected to a different output of the multi-layer substrate.

  • Publication number: 20060039528
    Abstract: A light detector includes a plurality of light receiving sections which are formed in a substrate and generate signal charges corresponding to the amount of incident light, and a plurality of wirings which are formed on the substrate and fetch the signal charges from the light receiving sections, wherein at least some of the plurality of wirings are disposed so as to overlap with other light receiving sections different from the light receiving sections connected to fetch the signal charges.

  • Publication number: 20050111612
    Abstract: An optical mask layer for a CT detector is disclosed and is disposed between the photodiode array and scintillator array of a CT detector. The optical mask layer, which may extend along the x-axis, z-axis, or both, is designed to absorb and/or reflect light emitted the scintillators of the scintillator array. Through this absorption and/or reflection, transference of light photons from a scintillator to the photodiode corresponding to a neighboring scintillator is reduced. This reduction in cross-talk reduces artifacts in a reconstructed image and therefore improves the diagnostic value of the image.
