扣带沟缘支立体定位数据集的构建及意义

目的:求得扣带沟缘支在笛卡尔三维坐标系中的立体定位数据集。方法:在笛卡尔坐标系中以扣带沟缘支的最内侧端点为起点,向外X值每隔3 mm取点,读取、记录各取样点的X、Y坐标值,Z值为所在层面距离零层面的数目与层距(3mm)的乘积。结果:构建出扣带沟缘支在三维坐标系中的立体定位数据集。结论:扣带沟缘支与笛卡尔三维坐标系有相对稳定的位置关系。

Construction of the stereotactic anatomy data set of the marginal ramus in cingulate sulcus and its significance

Objective:To obtain the stereotactic anatomy data set of the marginal ramus in cingulate sulcus. Methods:The most medial end of marginal ramus of the cingulate sulcus was set as a starting point in Descartes coordinate system,the each point at interval of 3 mm was identified,the X and Y coordinate values of which was recorded. The multiplication of the number of plane distancing from zero plane and plane distance was set as the Z value. Results:The three-dimensional anatomy data set of the marginal ramus in cingulate sulcus was constructed in the three-dimensional coordinates. Conclusions:The positional relationship between marginal ramus of the cingulate sulcus and Descartes three-dimensional coordinate is stable.
