  • Iterative reconstruction
    Patent number: 8655033
    Abstract: An improved iterative reconstruction method to reconstruct a first image includes generating an imaging beam, receiving said imaging beam on a detector array, generating projection data based on said imaging beams received by said detector array, providing said projection data to an image reconstructor, enlarging one of a plurality of voxels and a plurality of detectors of the provided projection data, reconstructing portions of the first image with the plurality of enlarged voxels or detectors, and iteratively reconstructing the portions of the first image to create a reconstructed image.
    Type: Grant
    Filed: October 28, 2009
    Date of Patent: February 18, 2014
    Assignees: General Electric Company, University of Notre Dame Du Lac, Purdue Research Foundation
    Inventors: Kai Zeng, Charles Addison Bouman, Jr., Bruno Kristiaan Bernard De Man, Jiang Hsieh, Ken David Sauer, Jean-Baptiste Daniel Marie Thibault, Zhou Yu
  • Methods and systems for improving spatial and temporal resolution of computed images of moving objects
    Patent number: 8233682
    Abstract: A method of improving a resolution of an image using image reconstruction is provided. The method includes acquiring scan data of an object and forward projecting a current image estimate of the scan data to generate calculated projection data. The method also includes applying a data-fit term and a regularization term to the scan data and the calculated projection data and modifying at least one of the data fit term and the regularization term to accommodate spatio-temporal information to form a reconstructed image from the scan data and the calculated projection data.

  • Method and system for iterative reconstruction
    Patent number: 8175115
    Abstract: A method for reconstructing an image of an object, the image comprising a plurality of image elements, is disclosed. The method includes accessing image data associated with the plurality of image elements, applying a first algorithm to the plurality of image elements, selecting a spatially non-homogenous set of the plurality of image elements, and applying an iterative algorithm to the set of image elements to reduce an amount of time necessary for reconstructing the image, or to improve an image quality at a fixed computation time, or both.
