Thomas A. Spraggins 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).

  • Method for calculating localized magnetic resonance spectra from a small number of spatially-encoded spectroscopic signals
    Patent number: 5081992
    Abstract: An MR imaging study precedes an MR spectroscopic study. Structural information from the imaging study is combined with MR spectra from the spectroscopic study to produce localized MR spectra.
    Type: Grant
    Filed: November 30, 1990
    Date of Patent: January 21, 1992
    Assignee: Siemens Medical Systems
    Inventors: David N. Levin, Xiaoping Hu, Paul C. Lauterbur, Thomas Spraggins
  • Method for retrospectively gating NMR data
    Patent number: 4961426
    Abstract: NMR imaging data are acquired using a variable phase-encoding gradient. NMR non-imaging data are acquired using fixed phase-encoding, and motion data are derived from such NMR non-imaging data. Gating data are extracted from the motion data and used to select from the NMR imaging data to produce gated image data. The gated image data are used to produce a reconstructed image.
