  • Multiband, multishot magnetic resonance elastography
    Patent number: 11131738
    Abstract: A method and system provides an acquisition scheme for generating magnetic resonance elastography displacement data with whole-sample coverage, high spatial resolution, and adequate SNR in a short scan time. The method and system can acquire in-plane and through-plane k-space shots over a volume of a sample divided into a plurality of slabs that each include a plurality of non-adjacent slices to obtain three dimensional multiband, multishot data, can apply multiband radio frequency refocusing pulses to the sample, can acquire navigators before readout, and can correct for non-linear motion errors.
    Type: Grant
    Filed: September 27, 2019
    Date of Patent: September 28, 2021
    Assignee: THE BOARD OF TRUSTEES OF THE UNIVERSITY OF ILLINOIS
    Inventors: Curtis L. Johnson, Bradley P. Sutton, Joseph L. Holtrop
  • Three dimensional multislab, multi-shot magnetic resonance elastography
    Patent number: 10551464
    Abstract: A method and system provides an acquisition scheme for generating MRE displacement data with whole-sample coverage, high spatial resolution, and adequate SNR in a short scan time. The method and system can acquire in-plane k-space shots over a volume of a sample divided into a plurality of slabs that each include a plurality of slices to obtain three dimensional multislab, multishot data, can apply refocusing pulses to the sample, can acquire navigators after the refocusing pulses, and can correct for phase errors based on an averaging of the navigators.
