探索建立颅脑MRI图像、断层标本图像及三维重建图像的对比数据模型

Establishment of a comparative data model for MRI brain images,sectional images and three-dimensional tomographic image reconstruction

目的利用计算机图像处理系统对颅脑主要重要结构进行三维成像,探索建立1套正常颅脑部MRI图像、断层标本及三维重建图像的数据对照计算机模型,为影像诊断及颅脑部手术定位提供形态依据。方法利用Microsoft Visual Studio将获得的MRI图像、断层标本图像及重建的三维图像建立数据模型。结果建立的数据模型提供了颅脑部正常解剖学影像学对比特点,构建了主要结构的三维立体模型图像,使抽象结构数字化、立体化、可视化,有助于对人脑的理解。结论本数据模型把颅脑结构的三维图像结合到标本MRI的对比图中,有利于初次接触颅脑断层的初学者。

Objective To establish a contrasting data computer model including a normal brain MRI images,sectional specimens and three-dimensional images by using computer imaging in order to provide morphological basis for diagnostic imaging and craniocerebral surgery positioning. Methods Microsoft Visual Studio was applied to get the MRI images,cadaver images and data modeling using three-dimensional images. Results The data model provided comparative characteristics of normal anatomic imaging of the brain and established the mages of three dimensional model with the main structures,e. g. digital,dimensional,and visual abstract structures. Conclusion The data model integrated threedimensional MRI images of the brain structures with the specimens at a relatively earlier stage,which may help beginners to learn brain sectional anatomy.
