摘　　要：该文针对医学超声图像噪声的特点提出了非线性滤波器。首先介绍了自适应中值滤波器的工作原理,然后用其与经典中值滤波器对含有不同噪声密度的肝癌超声图像进行去噪处理。实验结果对比表明:自适应中值滤波能够有效改善图像质量,在降低图像噪声的同时能较好的保持图像细节信息和视觉效果。In this paper, according to the characteristics of medical ultrasonic image noise nonlinear filter is presented. Firstly, this paper introduces the working principle of adaptive median filter, and then use it with the classical median filter to deal with the noise of ultrasonic image of liver cancer which contains different noise density. Compared to the experimental results： the adaptive median filter can improve the image quality effectively, it both may effectively remove the noise, and may maintain the mage details and visual effect well.
