Three‐dimensional Fourier encoding of simultaneously excited slices: Generalized acquisition and reconstruction framework

Simultaneous multislice (SMS) acquisitions have recently received much attention as a means of increasing single‐shot imaging speed. SMS acquisitions combine the advantages of single‐shot sampling and acceleration along the slice dimension which was previously limited to three‐dimensional (3D) volumetric acquisitions. A two‐dimensional description of SMS sampling and reconstruction has become established in the literature. Here, we present a more general 3D Fourier encoding and reconstruction formalism for SMS acquisitions that can easily be applied to non‐Cartesian SMS acquisitions.
