Figure 6.

Sample method comparison. Single-shot frames at end-inspiration (EI) are shown for the three free-breathing methods and 3 acquired views, along with frames at end-expiration (EE) from FB acquisitions for reference. Severe in and through-plane motion can be seen in free-breathing (FB) frames, which is largely eliminated in PROCO scans. FB-TF does reduce motion, but some residual in-plane motion can be seen in the SAX and 4CH end-inspiratory frames, which correspond to drastic through plane motion in the corresponding 2CH end-inspiratory frames.
