5.4 Color Mode Image Optimization
The Color mode is used to detect color flow information, and the color is designed to judge the direction
and speed of blood flow.
Generally, the color above the color bar indicates the flow towards the probe, while the color below the
color bar indicates the flow away from the probe. The brighter the color, the faster the flow speed, while
the darker the color, the slower the flow speed.
