What are the artifacts of Doppler techniques?
Attenuation
Refracture
Masking and enhancement
Beam width
Spectral broadening
High or low sensitivity
Filtering
Direction detection error
Spectral representation
Inadequate coupling
Production of harmonics due to a large signal distortion
Overlap artifact (aliasing)
Effect of the angle formed by the beam and the direction of flow
The Doppler color and energy modes do not suffer from the overlap artifact.
The Doppler energy mode does not suffer from the effect of the angle formed by the beam and the direction of flow.
The Doppler color mode can be useful in identifying high velocity flows.
The high PRF mode should be used with caution as it increases the intensity of the beam.
The overlap artifact can be useful in the Doppler color mode to identify high velocity flows.
