Wide dynamic range ultrasound echo receiver |
摘要 |
The wide dynamic range ultrasound receiver utilizes a multi-stage logarithmic amplifier in order to logarithmically amplify a returned echo signal. The output of the returned echo signal from the logarithmic amplifier is simply added to a saw-tooth wave Time Gain Control (TGC) signal. Thus, the wide dynamic range of the returned echo signals is simply converted into a video display.
