Symmetric and Transitive Registration of Image Sequences
Figure 3
The virtual tag lines and the corresponding short-axis slices of the tagged MRI scan are shown over the cardiac cycle (first row: end diastole; third row: end
systole) for (a) sequential recovery by , (b) sequential recovery by , (c) reference-based recovery by , and (d) reference-based recovery by . The registration algorithms and and the
difference between sequential and reference-based recovery are explained in
Section 3.2. The virtual tag lines were manually
positioned over the tagged MR image in the first frame (shown in the first row),
and then the deformation recovered from the anatomical image sequence was applied
to the virtual tag lines and they were overlaid over the tagged MR images in
the corresponding frames.
