Imaging Characteristics Affecting the Flow Convergence Assessment (A) The appearance of the flow convergence in the case of a hemispheric flow convergence. Because color-flow imaging is based on Doppler effect, with an increasing angle vs the beam of ultrasound, the flow display decreases and disappears at 90 degrees. Thus, a hemispheric flow convergence will appear as a “ball sitting on the jet.” Furthermore, this Doppler effect underscores the importance of measuring the radius in the direction of the ultrasound beam. (B) Schematic representation of the effect of the aliasing velocity on the shape of the flow convergence. With too-low aliasing velocity, the flow convergence appears football-like (pale yellow shape) and with too-high aliasing velocity the flow convergence appears pancake-like. Both are inappropriate for measurement, whereas the intense-yellow medium shape is appropriate for measurement.
