Influence of imaging parameters on flow tracking. (A) The cut-off velocity shows a clear frame rate dependence (see text for details). (B) The cut-off velocity is also dependent on the insonation angle. Best results are achieved when motion is close to the ultrasound beam direction (please see Figure 2). (C) Likewise, the accuracy of the flow direction estimate is insonation angle dependent. Best results are achieved when motion is close to the ultrasound beam direction (please see Figure 2).
