  • Correlation-based motion estimation of object to be imaged
    Patent number: 7587022
    Abstract: An imaging system in an example comprises an x-ray source, a detector, a data acquisition system (DAS), and a computer. The x-ray source emits a beam of x-rays toward an object to be imaged. The detector receives x-rays emitted by the x-ray source. The DAS is operably connected to the detector. The computer is operably connected to the DAS and programmed to estimate motion of the object on a correlation-basis and through employment of earlier-collected data.
    Type: Grant
    Filed: March 23, 2006
    Date of Patent: September 8, 2009
    Assignees: General Electric Company, University of Iowa Research Foundation
    Inventors: Jiang Hsieh, Yuchuan Wei, Ge Wang
  • CT image reconstruction through employment of function that describes interpreted movement of source around particular point of object
    Patent number: 7376213
    Abstract: A CT system in an example comprises an x-ray source, a detector, a data acquisition system (DAS), and a computer. The x-ray source emits a beam of x-rays toward an object to be imaged. The detector receives x-rays emitted by the x-ray source. The DAS is operably connected to the detector. The computer is operably connected to the DAS. The computer is programmed to reconstruct a CT image of the object to comprise a plurality of CT images, of a respective plurality of points of the object, through employment of a function that describes how many times a trajectory curve, of an interpretation of relative movement between the x-ray source and the object as that of the x-ray source, goes around each of the plurality of points of the object.

  • Methods, apparatus, and computer readable mediums for performing perfusion studies
    Patent number: 6934353
    Abstract: A method for conducting a perfusion study includes performing an initial full scan of an area of interest in an object, and performing at least one subsequent partial scan of the area of interest to detect motion of a contrast agent.
