Figure 6.

Velocity magnitude distribution from 4D flow data: in plane visualization (left) and 3D surface plot (right) in representative control (top) and stenotic (bottom) patients. The deviation from a flat profile in these 2 examples causes a simplified Bernoulli (SB) overestimation of a 20% and 136%, respectively.
