How do you fix color aliasing on ultrasound?

The artifact can be quickly remedied by lowering the baseline (if display of flow away from the transducer is not required), or increasing the PRF.

How do you correct aliasing of the spectral Doppler waveforms?

Aliasing in spectral Doppler distorts the flow information and must be corrected by adjusting the PRF before velocities can be measured. The PRF should be adjusted so normal flow does not create aliasing.

What is aliasing in sonography?

In sonographic. Doppler, the result of aliasing is an apparent change in direction of blood flow in. high-velocity areas, producing flow that appears to be backward. Aliasing can occur in pulsed and color Doppler; continuous-wave.
