When there are …
WebThe overall gain essentially increases the amplitude (or gain) of the rather weak returning ultrasound signals. In addition, echoes returning from deeper structures become progressively weaker because the ultrasound beam is attenuated, and compensation for this effect is required. This is achieved via the adjustment of TGC, whereby deeper echo ... WebGain - Measure of the strength of the ultrasound signal; overall gain amplifies all signals by a constant factor regardless of the depth TGC - Time Gain Compensation; Ability to …
