Abstract
A system suitable for reducing static or slow moving echoes from acoustic boundaries in a system such as pipe walls, blood vessels, tissue structures so that an image from flowing or time varying media such as water, oil, blood etc may be imaged more clearly, the system including an analog-to-digital converter for digitizing a received analog signal from a detector, means for digitally separating static or slow moving components of the digital signal, a digital-to-analog converter to provide an analog version of the separated static or slow moving components of the signal, and a subtractor to subtract the analog version of the static or the slow moving components of the signal from an analog signal received from a detector to produce an analog signal corresponding to the remaining flow components of the signal.
