Example TGC Curve on an Image
Each slider controls one dot on the curve. You can adjust the TGC sliders individually as
needed. Drag a slider to the left to decrease the gain, or drag it to the right to increase the
gain. You can also use the keyboard arrow keys; after clicking the 2D tab to select the
Gain control, press the down arrow key to select a TGC slider, then use the left and right
arrow keys to adjust it.
To show or hide the TGC curve, select
View > Image Display Properties > TGC Display
.
TGC Curve Display Options
Select
On
to show the curve, or select
Off
to hide the curve. If you select
Time Out
(the
default setting), the curve displays briefly when you start the application, adjust the gain,
or adjust an individual TGC slider.
The optional console houses physical sliders that control TGC. See
Adjusting Lateral Gain Compensation (LGC)
A set of LGC sliders increase or decrease the gain of segments of the returned signal,
when using some transducers. (Linear transducers do not support LGC.) These segments
are arcs one eighth of the full width of the scan. Adjusting LGC can enhance imaging of
the cardiac wall with some scanning orientations.
