Gain
Gain refers to amplifying the intensity of the returning sound waves on the screen display. Increasing the
gain brightens the image. Decreasing the gain darkens the image.
There are two ways to adjust gain: automatically and by using the gain sliders.
To adjust gain automatically

Tap AutoGain .
The system automatically balances the gain each time you tap this control. You can adjust the Auto Gain
level by using the
AutoGain Adjust control (see “Controls in 2D” on page 4-8).
To adjust gain by using the gain sliders

Drag a slider left or right, to decrease or increase the gain respectively:

In Color or Doppler, drag the C (Color) or the D (Doppler) gain slider at the bottom of the touch
panel.

In 2D or M Mode, tap the gain slider or the M (M Mode) gain slider at the bottom of the touch
panel. Two additional sliders appear.

The upper slider adjusts the near gain of the 2D image, controlling the display intensity in the
near field (nearer to the transducer).

The middle slider adjusts the far gain of the 2D image, controlling the display intensity in the far
field (further from the transducer).

The lower slider adjusts the overall gain.
Note Near and Far correspond to the time gain compensation (TGC) controls on some
other ultrasound systems.
