Gain
The B mode gain (2D gain) determines the amplifying factors for the received echoes and
the brightness of the ultrasound image. The echoes are amplified with the same gain value
regardless of depth.
To adjust the gain:
●
Rotate the B knob on the control panel clockwise to increase the value.
●
Rotate the B knob on the control panel anticlockwise to decrease the value.
TGC
TGC (Time Gain Compensation) is used to adjust the gain that allows compensation for
attenuation of the echoes over time (depth). It is adjustable during the real time scan
regardless of the imaging mode and display format.
TGC balances the image so that the density of echoes is the same throughout the image.
To adjust TGC:
●
Move the desired slider to the left to decrease the value.
●
Move the desired slider to the right to increase the value.
NOTE:
•
Modifications of TGC values cannot be saved if you shift to use another imaging

more than 3 seconds.
