Abstract：To reduce the influence of random noise during imaging according to the feature of high frequency ultrasound.A new line average noise reduction method was designed in this paper.In this method,each scan line of the ultrasonic image was consists of multi-ple-echo data sets,as the ultrasonic pulse was transmitted repeatedly and did average processing on the echoes for noise reducing.The algorithm did not need statistical information of the image,overcoming the problems of general filtering methods,which may reduce the frame frequency and blurs details.When de-noising,this method retained the true image information and improved the signal-to-noise ratio with out vague image.Experiments show that this design has a significant effect on noise filtering and better use for maintai-ning image details .
