  • PHASE LABELING USING SENSITIVITY ENCODING: DATA ACQUISITION AND IMAGE RECONSTRUCTION FOR GEOMETRIC DISTORTION CORRECTION IN EPI
    Publication number: 20110260726
    Abstract: A phase labeling using sensitivity encoding system and method for correcting geometric distortion caused by magnetic field inhomogeneity in echo planar imaging (EPI) uses local phase shifts derived directly from the EPI measurement itself, without the need for extra field map scans or coil sensitivity maps. The system and method employs parallel imaging and k-space trajectory modification to produce multiple images from a single acquisition. The EPI measurement is also used to derive sensitivity maps for parallel imaging reconstruction. The derived phase shifts are retrospectively applied to the EPI measurement for correction of geometric distortion in the measurement itself.

  • Ultrasonic elastography providing axial, orthogonal, and shear strain
    Patent number: 7331926
    Abstract: Ultrasonic signals obtained at a range of angles are fit to a material independent model to derive both axial and lateral strain and thus parameters dependent on lateral strain including Poisson's ratio and shear strain.

  • Elastographic imaging of in vivo soft tissue
    Patent number: 7166075
    Abstract: Elastographic images provide visualization in two or three dimensions of RF ablation lesions to guide in the ablation process. Compression may be applied using the RF probe. A similar technique may be applied to in vivo imaging of soft tissue without ablation.
