Kathryn Mary Littlejohn has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Methods and systems for volume fusion in diagnostic imaging
    Patent number: 7991450
    Abstract: Methods and systems for automatically fusing images are provided. The method includes acquiring scan data from a first imaging modality and fusing scan data from a second modality with the scan data from the first modality as scan data from the second modality is acquired and the method further includes displaying reconstructed images of the fused data.
    Type: Grant
    Filed: July 2, 2007
    Date of Patent: August 2, 2011
    Assignee: General Electric Company
    Inventors: Patrick Michael Virtue, Kathryn Mary Littlejohn, Katherine Redford Phillips, David Alan Littlejohn, Diane M. Miesbauer, Andre Van Nuffel

  • Multi modality imaging methods and apparatus
    Patent number: 7348564
    Abstract: A method for correcting emission data from Positron Emission Tomography (PET) or SPECT includes generating a plurality of computed tomography (CT) image data, selecting a portion of the CT image data, processing the selected CT data to generate a plurality of attenuation correction (CTAC) factors at the appropriate energy of the emission data, weighting the CTAC factors to generate an emission attenuation correction map wherein the weights are determined based on the axial location and the slice thickness of the CT data and the axial location and the slice thickness of the PET or SPECT data, and utilizing the generated attenuation correction map to generate an attenuation corrected PET image.
