  • MRI acquisition using 2D sense and partial fourier pace sampling
    Patent number: 8320646
    Abstract: An MRI system produces a three-dimensional image by acquiring NMR signals that fully sample a central region of k-space and partially sample peripheral k-space as a set of asymmetric radial sectors. The NMR signals are acquired with a plurality of receive channels and coils. An image is reconstructed using a homodyne reconstruction combined with SENSE processing.
    Type: Grant
    Filed: May 2, 2006
    Date of Patent: November 27, 2012
    Assignee: MAYO Foundation for Medical Education and Research

  • Method for acquiring MRI data from variable fields of view during continuous table motion
    Patent number: 7346383
    Abstract: MRA data is acquired from a large region of interest by translating the patient through the bore of the MRI system as a three-dimensional MRA data set are acquired. The pulse sequence is altered during the scan to change the lateral FOVL of the acquired image to better match the size of the region of interest along its length. Patient table movement is controlled to track a bolus of contrast agent as it passes through the region of interest. A seamless image of the entire region of interest is reconstructed after the acquired data is resampled in regions where the lateral FOVL is altered.
