  • Imaging table sag measurement and compensation method and apparatus
    Patent number: 6895105
    Abstract: An apparatus and method for use in correcting for table sag within a dual imaging system wherein the dual system includes two separate imaging configurations that define first and second imaging areas arranged sequentially along an imaging axis and that generate first and second imaging data sets, the apparatus including at least one sensor for identifying table sag and a compensator for modifying at least one data set to correct for table sag prior to combining the data sets to form a single image.
    Type: Grant
    Filed: December 21, 2000
    Date of Patent: May 17, 2005
    Assignee: General Electric Company
    Inventor: Scott D. Wollenweber
  • Method and system for estimating scatter in a pet scanner
    Patent number: 6590213
    Abstract: A method of processing an image data set of a 3D PET scanner to correct for scattered coincidence events, as well as a 3D PET scanner, are disclosed. The method of processing the image data set includes providing an image data set including a first plurality of data subsets respectively corresponding to a plurality of native slices. The method additionally includes axially downsampling the first plurality of data subsets to generate a second plurality of data subsets respectively corresponding to a plurality of super-slices. The method further includes calculating scatter in the second plurality of data subsets by way of a model-based scatter correction algorithm.
