5-6 Image Optimization
Increase the depth to see tissue in deeper locations, while decrease the depth to
see tissue in shallower locations.
TGC
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
of the image.
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.
Adjust the signal gain for the certain image area to get a balanced image.
Acoustic Power
Refers to the power of ultrasonic wave transmitted by the probe, the real-time
value of which is displayed in the upper part of the screen.
Use the <A.Power> knob to adjust the acoustic power. The adjusting range is 3.2-
100%.
Generally, increasing the acoustic power will increase the brightness and contrast
of the image and the force of penetration.
You should perform exams according to actual situation and follow the ALARA
Principle.
Focus
Refers to adjustment of focus of the ultrasonic beams, symbols as ― ‖ of which
are displayed on the right of the image.
Adjust the focus number through the [Focus Number] item on the touch screen.
Use the <Focus> deflector rod on the lower right part of the control panel to adjust
the focus position.
In B mode, available focus number can be switched among 1-4.
The area that is focused will be of a higher contrast and resolution.
The greater the number of focal zones, the slower the frame rate to image.
