大脑额上沟的三维重建与可视化

Three-dimensional reconstruction and visualization of cerebral superior frontal sulcus

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。

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.
