Design of slice multiplexed pulses for simultaneous multislice imaging

A slice-multiplexed rf pulse that imparts a different linear phase profile to each slice can be used to acquire multiple slices simultaneously and quickly. During read-out, slices are unaliased by using extra slice select gradient lobes, which rephase and dephase individual slices one at a time. Here we describe the improved design of multiplex pulses for 3 or more slices using the Shinnar-LeRoux formalism, and show preliminary in-vivo results.
