摘　　要：目的:构建大脑顶内沟基于联合间径(AC-PC)定位体系中的立体定位数据集及其平面投影回归方程。方法:将30名健康成年人颅脑横断层MRI数据经格式转化导入Photoshop CS软件包,经过严格的图像配准,建立以AC-PC中点为原点的三维立体坐标系,获得大脑冠状面图像上顶内沟的三维立体坐标值,以顶内沟最内侧点为起点,其中X值和Z值可直接在软件中读取,Y值为图像距离AC-PC平面的层数乘以图像层厚的积,所有取样点坐标值组成顶内沟在三维坐标系中的立体定位数据集。运用SPSS 22.0对所获得的数据进行统计,求解其空间拟合平面回归方程。结果:成功构建大脑顶内沟在三维坐标系中的立体定位数据集及其在空间各平面上的投影回归方程。冠状面上Z值对X值回归方程右侧:Z^(∧)=60.646+1.114 X+0.022 X^(2),左侧:Z^(∧)=73.409-1.939 X-0.032 X^(2);矢状面上Z值对Y值回归方程右侧:Z^(∧)=46.826-0.047 Y-0.001 Y^(2),左侧:Z^(∧)=36.822-0.480 Y-0.006 Y^(2);横断面上Y值对X值回归方程右侧:Z^(∧)=-53.739-0.752 X-0.003 X^(2),左侧:Z^(∧)=-62.721+1.265 X-0.011 X^(2)。结论:构建的顶内沟立体定位数据集预期对该沟附近的皮质功能区定位、病灶定位及未来机器人精准手术的策划具有指导意义。Objective:To construct the stereotatic localization data set and its plane projection regression equation of the intraparietal sulcus based on the AC-PC localization system.Methods:The transverse tomography data of 30 healthy adults were imported into the Photoshop CS software package by format transformation.After strict image registration,a three dimensional coordinate system with AC-PC midpoint as the origin was established to obtain the three-dimensional coordinate values of intraparietal sulcus in the coronal plane images of brain.The X-value and Z-value of the sample point were recorded directly from the software,and the Y-value was the product of the number of layers between the image layer and AC-PC plane,and interlayer spacing.The stereotactic localization data set of the intraparietal sulcus were constructed using all the coordinate values of sample points in intraparietal sulcus.The SPSS 22.0 software was used to calculate the obtained data,and solve the spatial fitting plane regression equation.Results:The data set of three-dimensional localization in three-dimensional coordinate system and its regression equation of projection on every plane of space of intraparietal sulcus were successfully constructed.On the right side of the regression equation of Z-value to X-value on the coronal plane:Z^(∧)=60.646+1.114 X+0.022 X^(2),on the left side:Z^(∧)=73.409-1.939 X-0.032 X^(2).On the right side of the sagittal plane regression equation of Z-value to Y-value:Z^(∧)=46.826-0.047 Y-0.001 Y^(2),on the left side:Z^(∧)=36.822-0.480 Y-0.006 Y^(2).On the right side of the cross-sectional Y-value to X-value regression equation:Z^(∧)=-53.739-0.752 X-0.003 X^(2),on the left side:Z^(∧)=-62.721+1.265 X-0.011 X^(2).Conclusions:The strereotatic localization data set of the intraparietal sulcus is expected to be of guiding significance for cortical functional area localization,lesion localization and robot precision surgery planning near the area of intraparietal sulcus.
