摘　　要：目的:介绍皮层重建和皮层展开方法并且探讨该方法在临床中的应用。方法:选用3例视觉或矫正视觉正常的志愿者,进行功能像扫描和T1WI的轴位、三维结构像的扫描;采用FreeSurfer软件对图像重建并将皮层展开,应用Afni软件进行视网膜定位功能像分析,最后绘制视网膜定位图。结果:经过皮层重建和皮层展开得到完整的展开的皮层,并用此方法划分视皮层功能区。结论:皮层重建展开的方法在临床可以有很大的应用价值。Objective:To introduce the methods of cortical surface reconstruction and flattening.Methods:3 volunteers with normal vision or correction vision were scaned in fMRI,3D-T1WI and 2D-T1WI with transverse section. We used software of freesurfer to reconstruct the cortex and flatten it,Afni was used to analyse retinotopic areas,and visual maps was drew.Results:The cerebral cortex can be flattened with cortical surface reconstruction and flattening; the visual cortical areas can be divided.Conclusion:The methods of cortical surface reconstruction and flattening are very useful in clinic.
