FIGURE 8.8: Optical flow applied to real patient data. The left column
shows from top to bottom: Target phase, floating phase and the floating phase
after motion correction. The right column shows the estimated flow vectors.
Only coronal slices are shown. Similarly, only half of the vectors are shown for
better visibility.
