Abstract
A system and method for producing images depicting a plurality of slice locations in a subject using a magnetic resonance imaging ('MRI'} system is provided. In particular, the system and method utilize time-shifted multiband radio frequency ('RF'} pulses to lower peak voltage and peak power requirements when using conventional multiband RF pulses. A time-shifted multiband RF pulse includes at least two component RF pulses, which may be single-band or multiband pulses. The component RF pulses are designed such that they do not have temporal footprints that completely overlap; although, they may have temporal foot-prints that partially overlap or do not overlap at all. The MRI system is used to acquire magnetic resonance signals formed in response to a time-shifted multiband RF pulse and, from these acquired signals, images depicting each of the plurality of slice locations in the subject are reconstructed.
