  • System and method of increasing temporal resolution of an X-ray image
    Patent number: 8768033
    Abstract: A system, method, and apparatus includes a computed tomography (CT) system having a rotatable gantry, an x-ray source, a generator, a detector having pixels and positioned to receive x-rays, and a computer. The computer is programmed to acquire CT data representative of an object, determine a first subset of the CT data, determine a second subset of the CT data, and determine a difference between the first and second subsets of the CT data to identify a motion region in the object. The computer is also programmed to update image data reconstructed from a first portion of the first subset of the CT data and corresponding to the region and reconstruct an image based on the updated image data and non-updated image data. The non-updated image data is reconstructed from a second portion the first subset of the CT data.

  • System and method for material segmentation utilizing computed tomography scans
    Patent number: 7983382
    Abstract: Certain embodiments provide a radiation analysis system for material segmentation utilizing computed tomography (CT) scans. The radiation analysis system includes an input module configured to input dual energy data. The dual energy scanned data includes first data corresponding to a first parameter and second data corresponding to a second parameter for a given scanned volume. The radiation analysis system also includes a processor configured to generate a scatter plot based on the dual energy data. The first data corresponds to a first axis and the second data corresponds to a second axis. The processor is configured to identify at least one material type based on the scatter plot.
