gain can adjust sensitivity of overall images (brightness). Rotate the knob of B mode could adjust B gain after

5 TGC
TGC with 8 adjustable slides: Slide the set of slider bars can change the depth gain of 2D images.
TGC returns signal amplifier to correct for the attenuation caused when adding depth. TGC balance the image
and make the density of echo uniformly distributed in images. Similarly the enlargement of every sliding
channel area is also different.
The range of TGC will redistribute according to the new depth while depth is changing.
Move the slide bar Left/Right can reduce/increase TGC.
