大脑额上沟的三维重建与可视化

目的:建立健康成人活体MR图像的大脑额上沟三维可视化模型,为探究额上沟的解剖结构特点及脑立体定向手术应用。方法:选取1名健康成年女性颅脑薄层MR扫描数据,将数据导入3D-Doctor软件,利用手动分割方法建立三维可视化模型并用不同颜色进行标记。结果:构建了大脑额上沟的三维可视化模式图,模式图成功显示了大脑额上沟、侧脑室及脑表面的立体形态以及与周围脑组织的结构关系。结论:大脑额上沟的三维可视化模型对额上沟解剖结构的识别、脑立体定向手术设计有重要价值。

Three-dimensional reconstruction and visualization of cerebral superior frontal sulcus

Objective:To establish a three-dimensional(3D) visualization model of cerebral superior frontal sulcus in a healthy adult people using MR image for exploring the anatomical characteristics of the superior frontal sulcus and application in brain stereotactic surgery. Methods:The brain slice MR scanning in one healthy adult female was harvested,the data of which was inputted to 3D-Doctor software. The 3D visualization model was reconstructed,and marked with different colors by the manual partition method. Results:The 3D visualization schema graph of cerebral superior frontal sulcus was constructed, which showed successfully the three-dimensional shape of cerebral superior frontal sulcus, lateral ventricle, brain surface and their structural relationships with surrounding brain. Conclusions:The 3D visualization model of cerebral superior frontal sulcus has an important value in the identification of the anatomical structure of superior frontal sulcus and design of stereotactic surgery.
