In simultaneous multi-slice (SMS) imaging, the multi-band RF pulses have complicated waveforms and may suffer from distortions, which can cause sideband excitations and result in image artifacts. We have proposed a simple method for correcting the RF distortions using a prescan of the RF output, which can be conveniently integrated in general SMS applications to suppress such artifacts with a negligible increase of scan time.
