4.5 Parameter adjustment about Color
mode
Color Doppler is used to observe the color blood flow and provide the flow direction and velocity
information of the blood flow. In general, red indicates the blood flow to the probe, blue indicates
the blood flow away from the probe, the brighter the color, the faster the blood flow, the darker the
color, and the slower the blood flow rate.

4.5.1 Color mode image parameter

During C-mode image scanning, the image parameter area on the left side of the screen provides
real-time parameter information, which allows you to adjust the following parameters:

The Color mode shares the probe sound power of the B mode ,When the acoustic power is
adjusted, the sound power of the two imaging modes changes synchronously.
Because the Color mode is superimposed by two-dimensional (B) mode and Doppler mode, the two
kinds of images change synchronously when magnifying or adjusting the depth.

4.5.2 Color mode image optimization

Gain
Resume To adjust the total sensitivity of the blood flow signal, the gain value is displayed in
real time in the image parameter area on the left side of the screen.
Influence If the gain is too high, it will amplify the noise; if the gain is too low, it is easy to
lose the blood flow signal.
Color Doppler flow can only be used as a reference for
doctors and can not be diagnosed directly. It is generally
compared with other machines or diagnosed by non-
ultrasonic means.
This device cannot perform long-term examination of the
fetus in Doppler mode.
