Freesurfer在癫痫病人脑模型重建中的应用

Application in Epilepsy Patients Brain Reconstruction Model

目的:用Freesurfer对癫痫病人的MRI数重建,分析MRI数据重建的方法对癫痫病人脑模型图进行分析,观察癫痫病人的脑模型图的特点。方法:用Freesurfer对MRI数据进行皮质重建、体积分割,视觉成像用于检查[1],主要用到的命令是recon-all、tkmedit、tksurfer,对检查成图进行视觉比对,观察重建是否正确。结果:证明Freesurfer可以很好地重建MRI数据,并且对Freesurfer的操作流程有一个更好的了解,通过重建可以顺利地完成癫痫病人脑网络成像的后续的步骤,最终可以更好地对癫痫病人的脑网络进行分析。结论:Freesuefer在MRI图形数据分析中非常重要,它是一个功能强大的软件,还可以进行拓扑结构修正、厚度计算、全脑分割等,在脑科学研究中具有非常广泛的用途。

Objective：Use Freesurfer to reconstruct MRI data of patients with epilepsy,analyze the brain network graphs using results of MRI reconstructions,observe the characteristics of patients＇brain networks.Methods：use Freesurfer to conduct cortex reconstruction,volume segmentationof MRI data.Visual imaging is used to evaluate the correctness of reconstruction[1].The commonly used command includes recon-all,tkmedit,and tksurfer.One visually inspects the reconstructed data to confirm if the results are correct or not.Results：the test confirmed that Freesurfer is able to correctly reconstructed MRI data.The reconstructed results can lay a solid foundation for the subsequent steps of epilepsy patients＇brain network analysis,and ultimately complete brain network analysis.Conclusion：Freesurfer is very important in MRI data analysis.It is apowerful software and have ability of the topological modification,thickness calculation,and whole brain segmentation.It has a very wide range of uses in brain science research.
