Objective: The stereoechography is kind of technique to realize 3-Dimension (3D) ultrasound visualization. It could explore the body inside of human and give the organ structure directly. Since the ultrasonic data are of poor quality and particularly noisy because of the speckles

we propose a new algorithm to solve this problem. Method: We present a algorithm by calculating the Nonstationary Degree of the image which could enhance the edge the image so that enhance the image and promote the quality. Result: We put the algorithm on the application to the stereovisual ultrasonic image about a liver of a rabbit and the 12-week infant. Conclusion: The stereovisual ultrasonic images enhanced by calculating the Nonstationary Degree of the image show a great improvement compare with the original ones. We could see the tissular structure clearly from the image.
