Simultaneous multi-slice (SMS) imaging has recently
gained in popularity, especially for 2D single-shot
sequences like EPI. Established reconstruction
techniques for SMS acquisitions are SENSE/GRAPPA or
slice-GRAPPA when CAIPIRINHA is used. With a few
exceptions, most SMS reconstructions require a two-step
approach to first disentangle the aliased slices, and
then perform in-plane parallel reconstruction, or vice
versa. We propose a 2D-SENSE reconstruction as a general
one-step approach to reconstruct SMS data with
arbitrarily undersampled Cartesian k-space (CAIPI-like
patterns) in phase and/or slice directions. In case of
additional in-plane undersampling it provides an
easy-to-implement, contrast independent, one-step
reconstruction along both undersampled dimensions.
