Acceleration imaging techniques such as parallel imaging and simultaneous multi-slice (SMS) imaging have been developed to achieve shorter acquisition time and larger FOV and incorporated into various imaging techniques including ultrafast imaging techniques such as echo-planar imaging (EPI). Here, we propose a new way to accelerate 3D spatiotemporal encoding (SPEN) imaging by combining SMS with controlled aliasing for parallel imaging results in higher acceleration (CAIPIRINHA) and split slice generalized auto-calibrating partially parallel acquisitions (Split Slice-GRAPPA).
