Adjusting the Gain, Depth, and TGC

This section provides information and instructions for adjusting the gain, depth, and TGC, using pan and zoom, freezing and unfreezing an image, and using the midline.

 The Gain, Depth, and TGC controls are available during live imaging.

  • The Gain control, accessed by swiping horizontally anywhere in the image, increases or decreases the gain percentage. When the Gain control is activated, the TGC (Time Gain Compensation) is also activated to adjust Near, Mid, and Far percentages.

Note: When in Color Doppler mode, the Gain control is labeled Color Gain.

  • The Depth control, accessed by swiping vertically anywhere in the image, increases or decreases the depth in centimeters. As you increase and decrease the Gain or Depth control, the border of the control is green. Once you select the value, the border turns to blue.

How do I adjust the gain?

  1. Touch anywhere on the screen and slide your finger slightly left or right to activate the Gain control.
  2. When the Gain control is visible, slide your finger right or left to increase or decrease the gain.
  3. When done, tap anywhere outside of the Gain control or simply wait until the control is no longer active.

How do I adjust the depth?

  1. Touch anywhere on the screen and slide your finger slightly up or down to activate the Depth control.
  2. When the Depth control is visible, slide your finger up or down to increase or decrease the depth.
  3. When done, tap anywhere outside of the Depth control or simply wait until the control is no longer active.

How do I adjust TGC on an image?

  1. Touch anywhere on the screen and slide your finger slightly left or right to activate the Gain control. When the Gain control is active, the TGC control is displayed at the bottom of the screen.
  2. Use the Near, Mid, and Far sliders to adjust the image as needed by tapping a slider and moving your finger right or left to increase or decrease the percentage.
  3. If necessary, tap Reset to reset the Near, Mid, and Far sliders to 50% (the factory default).
  4. Tap Done when finished.
