In this abstract we present a method to excite multiple slabs with arbitrary radiofrequency pulses while modulating the phase of each slab independently, allowing the simultaneous acquisition of multiple volumes without imaging the non-excited volume between the slabs. We show an example of a bilateral acquisition where the peak B1 amplitude is only marginally higher than that of a single slab with the same RF pulse, and that results in negligible signal loss.
