Figure 7

Short-axis reformats for patient C. Oblique short-axis reformats were reconstructed with no motion correction (a), rigid-body translational motion correction (b), and autofocus motion correction (c). The depiction of both non-cardiac and cardiac features (e.g., papillary muscles, magnified in inset images) improves significantly with autofocus motion correction. SI motion maps (d), AP motion maps (e), and RL motion maps (f) were derived from the autofocus algorithm and reformatted into the same oblique plane as (a–c). Lighter shades of red correspond to motion scales near 2× (white), and darker shades of red correspond to motion scales near 0× (black). The chest wall has little SI and RL motion, but moderate AP motion. An outline of the image features is superimposed on the motion maps for reference. A histogram of the SI, AP, and RL scale factors selected by the algorithm is shown in (g).
