Techniques to Avoid Aliasing: Lower frequency transducer or adjusting scale to its maximum
Most sonographers encounter aliasing with pulse spectral Doppler or color Doppler. Pulsed ultrasound doesn’t have a particular upper limit for displaying the Doppler shift. It’s commonly known as the Nyquist limit. High-velocity blood circulation causes Doppler shifts beyond the Nyquist limit resulting in aliasing. Often, aliasing is visible as a bright and turbulent flow in…
