Figure 8

Examples from in vivo imaging. The panels on the left show the contrast-enhanced echo image. The middle panels show the traced cavity border (purple line) and the tracking derived flow estimates (yellow arrows). The right panels show the colour-coded instantaneous normalized vorticity. All images are taken at the end of rapid filling. (A) Four-chamber view. Note the big counter-clockwise vortex formation in the center of the ventricle (orange colour). (B) Three-chamber view. In this view, the same vortex structure is shown as a clockwise rotation direction (blue colour). (C) Right ventricle. In a normal RV, only minor vortex formation around the tips of the tricuspid valve is found (orange and blue area at the RV base).
