  • System and method for performing tomographic image acquisition and reconstruction
    Patent number: 10825209
    Abstract: Systems and methods for tomographic reconstruction of an image include systems and methods for producing images from k-space data. A k-space data set of an imaged object is acquired using know k-space data acquisition systems and methods. A portion of the k-space data set is sampled so as to collect some portion of the k-space data. An image is then reconstructed from the collected portion of the k-space data set according to a convex optimization model.
    Type: Grant
    Filed: August 20, 2018
    Date of Patent: November 3, 2020
    Assignee: VIEWRAY TECHNOLOGIES, INC.

  • Correction of saturation banding artifacts in magnetic resonance imaging
    Patent number: 8929638
    Abstract: Systems and methods for correcting saturation banding artifacts in magnetic resonance imaging in which artifact and reference calibration scans are used to create one dimensional or two dimensional correction profiles, which are subsequently applied to actual diagnostic imaging scans to correct the saturation banding artifacts.
