【摘要】 目的:对活体器官与组织的三维成像及其不规则体积的计算,为肿瘤的空间定位、手术指导和判断脑组织发育异常等方面带来极大的帮助。本项目还将探究一种脑组织体积精确测量方法以促进神经科疾病的研究。方法:提出一种基于阈值分割后组织梯度化设置的体数据多层透明等值曲面可视化方法,本研究主要目的是在PC机上实现组织边界等值曲面的高精度、快速提取,最后将多层等值曲面同时可视化来清晰查看人体内部组织信息,并能对组织结构进行定量测量。结果与结论:应用本课题的研究算法得了脑、腹腔各脏器器官的三维重建图像。从中可以清晰地观察到内脏器官的形态,同时可以测量脑灰质与脑白质的体积比,心脏、肾脏、脾脏及肝脏等的体积等。更多还原

【Abstract】 Objective: The human living organ irregular volume calculation and 3D imaging method will give a potential hope to operation direction and tumor spatial location fixing.This project will also find a new method to study human brain volume calculation and this can enhance the neuroscience development.Methods: On the base of threshold segmentation,the methods of organ gradient setting and volume data transparent visualization are given.Those can be used to draw image fast and accurately.They can also be used to detect inner organ information of human body and measure organ structure.Results and Conclusions:By using those methods,the 3D reconstruction image of brain,hart,kidney and liver were formed.From those images the internal organs of the body can be observed clearly and we can derive volume ratio of grey matter and white matter and measure hart,kidney,liver and also tumor positioning.更多还原
