Abstract

Abstract: Anisotropic diffusion equation is used to reduce speckle noise.There is a theoretical analysis on the mechanism of reduction speckle noise.The paper presents an improved algorithm to reduce the speckle noise in the medical ultrasonic images based on anisotropic diffusion.The results show speckle noises in the medical ultrasonic images are removed and the image edge details are reserved.The method can reduce the speckle noise effectively and improve the quality of the medical ultrasonic images.

Key words: medical ultrasound image, anisotropic diffusion, denoising

摘要： 研究了各向异性扩散方程在医学超声图像去噪中的应用。在理论上对去噪原理进行了分析，并在此基础上采用改进的针对乘性噪声的各向异性扩散算法对医学超声图像去噪，实验结果表明，该方法在有效去除噪声的同时较好地保留了医学超声图像中的重要细节信息，使图像的细节部分清晰。该方法可以有效地去除超声图像斑纹噪声，提高图像的质量。

关键词: 医学超声图像, 各向异性扩散, 去噪
