中国数字人脑部体数据的任意切面绘制

目的:实现医学断层图像序列的三维重建及任意切面显示。方法:结合医学图像三维可视化的2种方法:表面绘制方法和体绘制方法,采用以三维矩阵数值运算与逻辑运算为基础的体数据面绘制算法。结果:可以从任意角度和位置来观察切面的形状、大小、灰度分布等各种生理病理特征。结论:通过分析子矩阵分解算法解决实时性要求与存储空间和运行时间的矛盾,克服了表面绘制不能体现内部数据的缺点,从一定程度上解决了体绘制的速度问题。

Surface rendering of section planes based on brain volume data of Chinese virtual human

Objective:To realize the three-dimensional reconstruction and show of the section planes of the medical slice images.Methods:Combination of the two traditional methods,surface rendering and volume rendering,were used based on the logical and numerical operating algorithm of the three-dimensional matrix.Results:The physiological and pathological characteristics such as shape,size and color distribution were observed in discretionarily oriented places or curved sectioning.Conclusion:Some data from experiments testing on the effects of the sub-matrix algorithm showed that the whole procedure of imaging was much more simplified and the runtime was much more reduced.The inner data were visible by surface rendering and computation speed was faster than volume rendering.
