Figure 5

Integrated systolic LV displacement of a representative animal. Anatomic labels (Sep = septum, Post = posterior, Lat = lateral, Ant = anterior) have been added for orientation. Three short axis planes, apex (A), mid-ventricle (B), and base (C), were color-coded for 3D displacement magnitude (mm), and overlaid on the projection of the 3D displacement vectors. The length and direction of the arrows represent the magnitude and direction of the in-plane component of displacement respectively. LV mid-wall surface was reconstructed and color-coded with through-plane motion (mm) (D). The position of the septum is marked for reference (red circle).
