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.
