  • Computer program, method, and system for hybrid CT attenuation correction
    Patent number: 7378660
    Abstract: Embodiments of the present invention provide a computer program, method, and system to facilitate hybrid CT attenuation correction. In one embodiment, the method generally includes acquiring data from a scanner, utilizing an ordered subset expectation maximization-bayesian algorithm to reconstruct the acquired data, and forward projecting the reconstructed data. Such a configuration minimizes the computing resources required for reconstruction and improves attenuation correction accuracy.
    Type: Grant
    Filed: September 26, 2006
    Date of Patent: May 27, 2008
    Assignee: Cardiovascular Imaging Technologies L.L.C.
    Inventors: James A. Case, Bai-Ling Hsu, S. James Cullom, Timothy M. Bateman, Paul Helmuth
