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 1cm. 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.
已开发出一种具有可编程时间增益控制(TGC)的超声接收器。TCG曲线由顺序选通的模拟开关合成,每个开关在1厘米的范围内控制接收器增益。使用具有可编程TGC曲线的接收器进行的诊断研究表明,在接收回波的幅度均衡和输出显示方面取得了更好的结果。
