Pulse wave doppler Aliasing is common problem usually encountered while interrogating vessels with pulse wave.
Image (a) showed a typical example of pulse wave aliasing.
PRF was too low = 1395.
This caused wrapping of the signal. As the sampled velocity is above the Nyquist limit .
In image (b) Aliasing has been corrected by raising the PRF value to 6250. This is a major effective solution to pulse wave aliasing.
The sampled signal must be consistently below the Nyquist limit.
