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.

Multiband RF/MRI pulse design for multichannel transmitter

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.
