Patents by Inventor Nikolai I. Avdievich

Nikolai I. Avdievich 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: 10698046
    Abstract: There is provided a novel method and circuit of compensating for cross-talk between pairs of adjacent array elements of a transceiver phased array and double-tuned transceiver arrays for a magnetic resonance system using a resonant inductive decoupling circuit. The geometry and size of the resonant inductive decoupling circuit allows for the decoupling circuit to compensate for the cross-talk between array elements, including the reactive and resistive components of the mutual impedance while being sufficiently small to not distort a RF magnetic field of the array elements produced within a sample.
    Type: Grant
    Filed: March 25, 2019
    Date of Patent: June 30, 2020
    Assignee: Transarray LLC
    Inventors: Nikolai I. Avdievich, Hoby P. Hetherington, Jullie W. Pan

  • Patent number: 9316709
    Abstract: The inventive subject matter as a whole is an improved transceiver apparatus and system for diagnostic evaluations of living subject, human or animal; and is particularly effective as a clinical tool for the spectroscopic scanning or magnetic resonance imaging of humans suspected of being afflicted with a particular disease, disorder, or pathology. The improved transceiver apparatus is used as an essential component in a computer controlled system suitable for magnetic resonance imaging (“MRI”), or nuclear magnetic resonance spectroscopy (“MRS”), and/or nuclear magnetic resonance spectroscopic imaging (“MRSI”); and the present improvement of these electromagnetic signaling systems will provide far more accurate and precise visual images and accumulated data for the clinician or surgeon, as well as serve as a basis upon which to make a diagnosis and decide upon a mode of therapeutic treatment for that individual.
