Turbulence can be visualized with 0.8mm in plane 4D flow resolution in one bifurcation phantom, using a partially inflated balloon and a cardiac pump at 1.3ml/s, 60bpm, VENC of 40 cm/s and systemic pressure.
Figure 1) Turbulence (orange arrows) visualized with 4D flow in a glass phantom (water, 25°C, 1.3ml/s, VENC=40 cm/s)
Figure 2) Turbulence (orange arrows) visualized with injected ink in a PVA phantom by a camera (time frame top to bottom, 30fps, 320x240, 33% glycerol solution, 25°C, 0.85ml/s).
