Parameters adjustment for B mode
B mode is the system's default imaging mode. The system displays echoes in two
dimensions by assigning a brightness level based on the echo signal amplitude. To
achieve the best possible image quality, properly adjust the display brightness, gain,
depth settings, viewing angle, and exam type. Also, select an optimization setting that
best matches your needs.
4.3.1
B mode image parameter
During B-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:
Adjustment method

Gain, depth, one-button optimization
SoftKey adjustment
Frequency, extended imaging, frame-related, dynamic
range, effect, focus, spatial compounding, image
enhancement, pseudo-color map, left and right turning, up
and down, sound power, TGC, TSI
4.3.2
B mode image optimization
Gain
Resume
The total gain of the image in the two-dimensional mode
，
displays in real
time on the image parameter area on the left side of the screen.
Effect
By increasing the brightness of the gain image, more echo signals can be
observed, but at the same time, there will be more noise.
。
Depth
Resume
For adjusting the depth of the image display, the range of image depth can
be adjusted by different probes. The depth value is displayed in the image
parameter area on the left side of the screen in real time.
Effect
The deeper the depth, the wider the observed tissue; the smaller the depth,
the shallower the observed tissue. When the depth increases, the frame
rate decreases.
TGC
Resume
The attenuation caused by increasing tissue depth is compensated and the
depth gain is adjusted in different segments .
