*Note that not all systems have separate wall filter controls for color<br />
Doppler. Usually the wall filters are set as a percentage of the<br />
color scale setting.<br />
Interpreting The Color Bar<br />
The color bar can be compared with the format of the Doppler<br />
spectrum. The color bar presents both flow directionality and average<br />
flow velocities (or frequency shifts). As with spectral Doppler, the<br />
baseline represents no flow detected. Aliasing results in a “wrapping”<br />
of the colors around the baseline.<br />
