The Power 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.

4.6.2 Power mode image optimization

Because of the same Doppler color imaging, most of the image parameter adjustment items in Power
mode are consistent with Color mode. Therefore,the following is just a introduction of the image
parameters independently adjusted in Power mode.
Gain
Resume
Adjusting the total sensitivity of the blood flow energy signal, the gain value is
displayed in real time in the image parameter area above the screen.
Effect
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
Map
Resume
Color image display effect parameters.
Effect
The energy map provides perfusion information of the image and is sensitive to low-
speed blood flow.
Dynamic range
Resume
Controls how the echo intensity is converted into a color signal.
Effect
After adjusting, it has greater sensitivity to the low energy signal, and increases the
display range of the signal.
Steer
Resume
Used to tilt left and right color blood flow images to obtain more information without
moving the probe.
Effect
Changing the incident direction of the acoustic beam in color mode, thus changing
the angle between the acoustic beam and the direction of blood flow, is only effective
for the linear array probe.
