The goal of this work was to use SMS acceleration to
speed up the acquisition of EPI navigators. Validation
studies were performed in phantoms and in-vivo to
demonstrate that SMS accelerated navigators can lead to
accurate motion detection over a range of motion values.
Furthermore, prospective motion correction was
demonstrated by adding SMS navigators into an inversion
prepared gradient echo (MPRAGE) sequence.
