6.3 Color Mode
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.
• During color mode imaging, menus of image optimizing for B-Mode and C-Mode are
displayed on the touch screen at the same time. You can switch between the 2 modes by
clicking the mode tabs.
• In Color Mode, acoustic power is synchronous with that of B Mode. Adjustment of the depth
or zoom to the B Mode image will lead to corresponding changes in Color Mode image.
