摘要
在得到人体实体切片序列图像中大脑器官的边缘轮廓线的基础上,提取图像中的标尺,利用图像中提供的标尺计算像素和实物的比例关系;用积分叠加原理计算大脑切片的面积和体积,建立了大脑器官定量分析的数学模型。用辐照仿真人体模型作为实验对象,根据论文提供的数学模型计算其大脑的体积并与真值比较,验证定量分析原理和数学模型是可行的。
On the base of distilling edges from images of human slices, by calibrating the gauge, the ratio relationship between the pixels of the gauge and the real section areas were obtained. Thus, the mathematical model of the cerebrum can be constructed for the use of quantitatively analyzing. The volume of cerebrum has got by piling up the solid slices according to the integral principle. By comparing with the authentic data of the phantom of the human cerebrum in the experiment, the correctness of the quantitative analysis mathematical model has been verified.
