  • Methods for positive emission tomography (PET) target image segmentation
    Patent number: 8026488
    Abstract: A method for positive emission tomography (PET) target image segmentation is provided. The method comprises capturing and digitizing image data of a selected target, determining an initial concentration ratio based on an initial source background ratio and an initial volume estimate of the selected target employing a concentration ratio table, determining a desired threshold from the initial concentration ratio and the initial volume estimate employing a threshold table, and determining a final volume estimate of the selected target based on the determined desired threshold.
    Type: Grant

  • Alignment system to overlay abdominal computer aided tomography and magnetic resonance anatomy with single photon emission tomography
    Patent number: 5299253
    Abstract: The invention is a machine based alignment system for imaging with a contrasting marker (fiducial marker) attached to a support means for providing a set of markings which uniquely identify each cross-section of an imaged object in relation to other registered images.The invention also provides a method for using the alignment system.
