图像滤波技术在B型超声诊断仪中的应用研究

目的：依据医学超声图像固有特点，对B型超声医学图像滤波技术进行研究，以达到大幅度提高图像质量的目的。方法：通过Matlab等工具实现B型超声诊断仪图像的均值滤波、中值滤波、自适应中值滤波、小波变换以及各向异性扩散方程滤波。结果：对常见的B型超声诊断仪滤波算法进行了比较与研究。结论：所有的滤波方法对图像信号均有一定程度的增强，对噪声亦有抑制。均方误差反映了滤波图像在抑制噪声的同时，对细节的保持情况和超声医学图像两者之间达到一个最佳的平衡。

Image filtering technology in the application of B type ultrasonic diagnosis instrument

Objective：Due to the inherent characteristics of medical ultrasound images, the study of B-type ultrasonic medical image filtering technique, you can make the image quality greatly improved.Methods： through tools such as Matlab, for b-mode ultrasonic image Adaptive mean filter, median filter, median filter, wavelet transform, anisotropic diffusion equation filtering;Results： compares the common b-mode ultrasonic filtering algorithms and research.Conclusion：all the filtering method for image signal is enhanced to a certain extent, suppression for noise, too. Mean square error reflects filtering image noise, while attention to detail, keep, for medical ultrasonic images in the hope that is in between the two to achieve an optimal balance.
