We introduce an efficient Mult-Shot Diffusion-Weighted (DW) 3D-GRASE
acquisition and reconstruction technique to produce DW image volumes
free of motion-induced phase artifacts, without relying on explicit
measurement or inference of the phase information. The method replaces
navigators measurements by a single reference scan for the whole
acquisition. Virtual Coil concepts for Parallel Imaging techniques are
used to map the multi-shot data onto a k-space signal with consistent
phase information.
