Multiband RF pulses are central to the signal excitation
in simultaneous multislice acquisitions. The peak
amplitude has been a limiting factor in multiband RF
design, especially in multiband spin-echo pulse design.
In this work, nonlinear-phase multiband pulses, which
have reduced peak power compared to linear-phase pulses,
are designed. A pair of 90-180 nonlinear-phase
multiband pulses are applied to generate a linear-phase
echo. An additional reference phase is applied to each
individual excited band to further reduce the peak power
of the multiband pulse.
