  • Multiband RF/MRI pulse design for multichannel transmitter
    Patent number: 10684337
    Abstract: A method for designing one or more multichannel, multiband radio frequency (“RF”) pulses for use with a magnetic resonance imaging (“MRI”) system is provided. The method includes determining a number of RF amplitude modulations and a number of RF phase modulations for each channel in a multichannel RF coil by minimizing an objective function that includes a complex-valued vector. The objective function also contains a system matrix that accounts for both a spatial sensitivity profile of each channel in the multichannel RF coil and a magnetic field map for each excitation band in the multiband RF pulse.
    Type: Grant
    Filed: January 24, 2014
    Date of Patent: June 16, 2020
    Assignee: Regents of the University of Minnesota
    Inventors: Xiaoping Wu, Pierre-Francois Van De Moortele, Sebastian Schmitter, Kamil Ugurbil, Edward Auerbach
  • Systems and methods for designing magnetic resonance imaging radio frequency pulses that are robust against physiological motion errors
    Patent number: 10247803
    Abstract: Systems and methods for designing and/or using radio frequency (“RF”) pulses for in-vivo MRI applications, where the RF pulses are robust against errors due to physiological motion of organs during the respiratory cycle. For example, RF pulses are designed based on multi-channel B1+ maps correlated to different positions of the respiratory cycle.
