Using the k-space-based reconstruction, the synthesized 3D navigator has similar
performance with the acquired 3D navigator for multi-slab and outperforms the
2D navigator for both multi-slab and SMSlab.
Figure 4. The 1 mm isotropic mean DWI images (a), MD (b)
and FA maps (c) of SMSlab DTI with 20 diffusion directions, from three
orthogonal views. The images are reconstructed by k-space-based reconstruction with
a synthesized 3D navigator.

3. The reconstructed images from two volunteers, by k-space-based reconstruction
with (a) the acquired (for SMSlab) or extracted (for multi-slab) 2D navigator,
(b) the synthesized 3D navigator and (c) the acquired 3D navigator (only for
multi-slab).
