Image Optimization 5-5
5.4 B
Mode
B mode is the basic imaging mode that displays real-time images of anatomical tissues and
organs.
5.4.1
B Mode Exam Protocol
1. Enter the patient information, and select the appropriate probe and exam mode.
2. Press <B> on the control panel to enter B mode.
3. Adjust parameters to optimize the image.
4. Perform other operations (e.g. measurement and calculation) if necessary.
In real-time scanning of all image modes, press <B> on the control panel to return to B mode.
5.4.2
B Mode Parameters
In B mode scanning, the image parameter area in the upper left corner of the screen displays
the real-time parameter values as follows:
Display F
D G

B Dynamic
Range
5.4.3
B Mode Image Optimization
Gain
Description
To adjust the gain of the whole receiving information in B mode. The real-time
gain value is displayed in the image parameter area in the upper left corner of
the screen.
Operation
Rotate the <Gain/iTouch> knob clockwise to increase the gain, and
anticlockwise to decrease.
The adjusting range is 0-100.
Effects
Increasing the gain will brighten the image and you can see more received
signals. However, noise may also be increased.
Depth
Description
This function is used to adjust the display depth of sampling, the real-time
value of which is displayed on the image parameter area in the upper left
corner of the screen.
Operation
Use the <Depth/Zoom> knob to adjust the depth. The adjustable depth values
vary depending upon the probe types.
Effects
Increase the depth to see tissue in deeper locations, while decrease the depth
to see tissue in shallower locations.
Impacts
Depth increase will cause a decrease in the frame rate.
TGC
Description
The system compensates the signals from deeper tissue by segments to
optimize the image.
There are 8-segment TGC sliders on the control panel corresponding to the
areas in the image.
