虚拟中国人女性一号宫颈的任意剖面显示的研究

Study on show of section planes of Virtual Chinese Female No.1

目的:研究中国数字化女性虚拟人宫颈的剖面显示问题.方法:根据图像数据特点,从所获得的女性骨盆数据中提取出女性宫颈数据,然后通过计算机相邻两层图像之间像素对的相同程度来对其进行平移配准,最后利用C++Builder语言编程实现剖面显示.结果:使用文中提及的方法对图像进行配准处理,我们发现在配准搜索过程中出现局部相似性最大的情况,从而使得搜索提前结束.结论:我们建议采用基于最大互信息量配准的方法,通过统计方法来表达图像像素的相似性特征,并利用优化算法有效克服局部极值,以便提高图像显示的精度,从而较好地应用于虚拟人体的其他部位的剖面显示.

AIM: To find a solution for the uterus section show of digitized Virtual Chinese Female No.1 (VCH-F1) image data. METHODS: On the basis of the features of the image data, the authors gleaned the female uterus data from the acquired data of pelvic, implemented image registration with parallel moving, and displayed the section show of the uterus by using the program language of C++ Builder. RESULTS: Local comparability maxima were sometimes found in searching for image registration, and as a result the search had to be stopped. CONCLUSION: For better image of the section show of other parts of the body, registration based on the criteria of maximization of mutual information and optimizing arithmetic are recommended in expressing the comparability of image pixels and overcoming the local maxima.
