  • Magnetic resonance relaxation along a fictitious field
    Patent number: 9222999
    Abstract: A system includes a driving module, a processor, and a readout module. The driving module is configured to apply a perturbation to a sample. The processor is configured to define a plurality of different rotating frames relative to the perturbation, wherein each frame has a corresponding fictitious field. The readout module is coupled to the processor and is configured to generate an output based on relaxation of the sample as a function of the perturbation.
    Type: Grant
    Filed: April 9, 2012
    Date of Patent: December 29, 2015
    Assignee: Regents of the University of Minnesota
    Inventors: Shalom Michaeli, Silvia Mangia, Dennis J. Sorce, Michael G. Garwood, Timo Liimatainen

  • Magnetic resonance contrast using fictitious field relaxation
    Patent number: 7932719
    Abstract: A system includes a signal generator and a processor. The signal generator is configured to couple with a magnetic resonance transmitter coil. The processor is configured to execute instructions to control the signal generator. The instructions include forming a sequence of waveforms. The sequence is configured to generate spin relaxation in a fictitious field in a third rotating frame of reference based on at least one magnetic field component that arises based on an effective field in a second rotating frame of reference. The third rotating frame of reference is of a higher order than the second rotating frame of reference and the second rotating frame of reference is of a higher order than the first rotating frame of reference.
