Method of displaying stream lines of an inhomogeneous flowing medium and a device therefor

摘要: A method and device to display in real time a stream line of an inhomogeneous flowing medium such as blood flow heart, is disclosed. The object scanned several times by ultrasonic beam pulses. Echoes appearing within predetermined interval at each point the are combined produce image speckles formed flow. process repeated times, obtain motion speckles. Differences between images spatially correlated obtained interval, segments lines. successive frames or lines can be used speckle methods scanning disclosed differences
