Image Optimization 5-5
Operation Use the [Depth] deflector rod on the control panel to adjust.
The adjustable depth values vary depending upon the probe types.
Impacts
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.
Operation
To increase the gain compensation at an area of interest, move the TGC slider to the
right. To decrease the gain compensation at the corresponding area of interest, move the
TGC slider to the left.
About 1.5s after the adjustment is finished, the TGC curve disappears.
Impacts
Adjust the signal gain for the certain image area to get a balanced image.
Acoustic power
Description Refers to the power of ultrasonic wave transmitted by the probe, the real-time value of
which is displayed in the image parameter area in the upper left corner of the screen.
Operation Tap [A. Power] to adjust the parameters.
The adjusting range is 0.1%-100%.
Generally, increasing the acoustic power will increase the brightness and contrast of the
image as well as the force of penetration.
Impacts
You should perform exams according to actual situation and follow the ALARA Principle.
Image display adjustment
Description More information can be obtained without moving the probe or changing the sampling
position.

FOV
position To change the scan range, click [FOV] on the touch screen to enter the FOV range
and FOV position adjustment status.
Press <Set> to switch the FOV range and FOV position.
Rotate the trackball to adjust FOV position or the FOV range.
When the scan range is adjusted to the widest, the FOV position cannot be changed.
You can get a much larger field of view when selecting a larger FOV, but the frame rate
will decrease.
PW Steer To steer the beam the probe transmits.
Toggle <Steer> knob to complete the adjustment.
