Aliasing Colour Doppler is a pulse echo technique It is subject to the Nysquist limit Aliasing occurs when the Doppler shift exceeds PRF/2 Doppler shifts above the Nyquist limit are shown in the wrong colour This needs to be differentiated from flow reversal (boundary lines separation in flow reversal) The techniques for eliminating aliasing in Read more about Colour Doppler : Aliasing[…]
