Abstract: The technology of medical image processing and analyzing can provide more clear and accurate images and more useful quantitative information for the doctor to assist the diagnosis and treatment. The development of algorithms such as segmentation， registration and 3D visualization is the motivation of medical image processing and analyzing， while the software platforms based on these algorithms are the accelerators of medical image processing and analyzing. Many software platforms have been designed for scientific research or providing wieldy assistant tool for certain users. This paper introduces some mainstream platforms， and discusses the advantages and shortcomings of these platforms adequately. Our aim is to spread the applications of medical image processing and analyzing software platform， and motivate the researchers to contribute to the development of the software platforms.

Key words: segmentation, registration, visualization, software platform

摘要： 医学图像处理与分析技术可以给医生提供更清晰、更准确的信息，以利于疾病的诊断和鉴别诊断。医学图像分割、医学图像配准以及三维可视化等算法是医学图像处理与分析发展的源动力，而基于这些算法研发的软件平台是医学图像处理与分析前进的加速器。现有的医学图像处理与分析软件平台极大地便利了医学影像领域的研究者与应用者，大大加快了医学影像发展的步伐。对国内外医学图像处理与分析的软件平台进行了比较系统的归纳，详细地介绍了各类主流软件平台，并充分地讨论了各种平台的优缺点，旨在推广医学图像处理与分析软件平台在国内的应用，并激发国内医学影像领域的研究者为医学图像处理与分析软件平台贡献自己的力量。
