WebGain: Screen brightness can be adjusted manually by two function buttons—gain and time-gain compensation (TGC)—on ultrasound machines that have TGC built in. Excessive … WebGain is the amplification of the ultrasound signals your transducer records. Each echo gets turned into a lighter or darker (depending on the echogenicity) pixel on your machine's screen, and gain dictates how much each echo is amplified. If you turn the gain all the way down, you will have a very dark image and will have a hard time making out ...
