TGC
This is a parameter to determine the receive gain (offset) in relationship to the depth direction.
The receive gain relative to the depth direction of an image is adjusted for individual transducers and is set to a stan-
dard value so that normally you can acquire a good view of the image even if all TGCs are positioned to the center .
Additionally, if you want to partially adjust the image to the desired brightness (receive gain) level, use the TGC slider
volume(s) .
Pressing the [TGC] button in the operation button area will display the TGC pop-up menu .

4 .4 Basic Scanning Mode
Longitudinally divides an ultrasound
image into eight equal parts based on
its depth, and assigns TGC gains in
increasing or decreasing depth order .
By dragging each of the eight control
points (TGC slider volumes) from side
to side, the brightness of each part is
adjusted based on its own depth .
Only live images are adjustable .
Parameter range:
-15 to 15 dB, 0 dB at the center
