Mean rostral–caudal and ventral–dorsal displacements of tissues in the mid-sagittal plane. The average rostral–caudal displacement was −0.12 ± 0.06 mm compared to 1.0 mm thickness of axial slices. The average ventral–dorsal displacement was 0.88 ± 0.03 and this value was comparable to the ventral sector displacement (4.9–9.5 mm) that was from a tissue volume in the same region of interest measured in axial slices. Note that rostral–caudal displacement is orthogonal to axial images; positive (+) direction is rostral, and ventral–dorsal displacement is in same direction as ventral–dorsal in axial images; positive (+) direction is ventral.
