I am showing you a continuous-wave Doppler in the short axis around the aortic-valve level. This is a TR signal with a peak velocity of slightly more than 4 m/s, so you can see that there's ...

Measuring the maximum blood flow velocity by continuous-wave Doppler from different windows (suprasternal notch, apical, and parasternal long axis) determines the maximum peak pressure gradient.

We analysed the pulse wave velocity (PWV) measured by the Doppler method with 2D guidance and its reproducibility in different arterial segments in 15 men with coronary artery disease.
