An ultrasound receiver with programmable time gain control (TGC) has been developed. The TCG curve is synthesized from sequentially gated analog switches, each of which controls receiver gain over a range of lcm Diagnostic studies using a receiver with the programmable TGC curve show improved results in the amplitude equalization of received echoes and in the output display.
