Patents by Inventor John G. Georgiadis

John G. Georgiadis 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: 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.

  • Patent number: 10261157
    Abstract: Aspects of the subject disclosure include a system that applies magnetic resonance elastography to a sample to obtain uncorrected k-space data where the magnetic resonance elastography utilizes a multi-shot spin-echo sequence with variable density spiral readout gradients, and adjusts the uncorrected k-space data to corrected k-space data by adjusting a k-space trajectory by shifting a center point for each shot to a new center point according to signal intensity and by adjusting a phase for each shot based on a phase offset that is determined according to the signal intensity.

  • Publication number: 20140232395
    Abstract: Aspects of the subject disclosure may include, for example, a system that applies magnetic resonance elastography to a sample to obtain uncorrected k-space data where the magnetic resonance elastography utilizes a multi-shot spin-echo sequence with variable density spiral readout gradients, and adjusts the uncorrected k-space data to corrected k-space data by adjusting a k-space trajectory by shifting a center point for each shot to a new center point according to signal intensity and by adjusting a phase for each shot based on a phase offset that is determined according to the signal intensity. Other embodiments are disclosed.
