FIGURE 8.

Comparison of T₁ weighted GRE images acquired for two slices with greedy registration (slice 1/12 – top row, and 6/12 – bottom row). The volunteer was not immobilised and was asked to move deliberately. Images are shown without correction (MoCo OFF ‐ left) and with motion correction (MoCo on ‐ right). Images are sums of all measurements acquired either without or with motion correction. Motion scores describing extent of movement were: 4.53 mm (left) and 6.40 mm (right). The ratio of the variance of the image Laplacian for corrected vs uncorrected was: 0.91 (top) and 1.59 (bottom).
