Patents by Inventor Mark CHIEW

Mark CHIEW 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).

  • Patent number: 12153110
    Abstract: A method of performing magnetic resonance spectroscopic imaging (MRSI) includes transmitting a multi-slice excitation pulse through tissue, the multi-slice excitation pulse configured to generate multi-slice MRSI signals. The method also includes performing density weighted concentric ring acquisition on the multi-slice MRSI signals. The method further includes receiving the generated multi-slice MRSI signals in a plurality of sensors disposed in various locations around the tissue. Imaging data is reconstructed based on the acquired imaging signals. A representation of the data is displayed.
    Type: Grant
    Filed: November 28, 2023
    Date of Patent: November 26, 2024
    Assignee: Purdue Research Foundation
    Inventors: Uzay Emir, Mark Chiew

  • Patent number: 11828822
    Abstract: A method of performing magnetic resonance spectroscopic imaging (MRSI) measures neurochemical profiles over larger regions non-invasively. The method includes transmitting a multi-slice excitation pulse through tissue, the multi-slice excitation pulse configured to generate multi-slice MRSI signals. The method also includes performing density weighted concentric ring acquisition on the multi-slice MRSI signals. The method further includes receiving the generated multi-slice MRSI signals in a plurality of sensors disposed in various locations around the tissue. Imaging data is reconstructed based on the acquired imaging signals. A representation of the data is displayed.

  • Patent number: 11802926
    Abstract: The present disclosure is directed to radially-based magnetic resonance imaging. In any one or more embodiments, the present methods and systems provide that the angular increment between subsequent radial k-space spokes to be sampled to provide the imaging is performed for a predetermined or pre-defined restricted set of reconstruction window sizes (numbers of radial spokes per frame), or limited views, to maximize the uniformity of sampling within the restricted set of window sizes.
