Abstract
A diagnostic medical ultrasonic imaging system includes a gain processor that varies the receive signal path gain as a function of the signal to noise ratio of the echo signal. Background noise is either acquired or modeled in real time using currently prevailing imaging parameters, and acquired echo signals are compared with the acquired or modeled background noise values. The receive gain is controlled as a function of this comparison to improve the signal-to-noise ratio, and to reduce or prevent the amplification of echo signals that are not greater than the background noise level.
