Color Mode Image Optimization
The Color mode is used to detect color flow, 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 is, the faster the flow speed
becomes; while the darker the color is, the slower the flow speed becomes.
