In the last decade several methods for extracting the human cerebral cortex from magnetic resonance images have been proposed. Studies comparing these methods have been few. In this study we compare a recent cortical extraction method with FreeSurfer, which has been widespread in the scientific community during recent years. The comparison is performed using realistic phantoms generated from surfaces extracted from original brain scans. The geometrical accuracy of the reconstructed surfaces is compared to the surfaces extracted from the original scan. We found that our method is comparable with FreeSurfer in terms of accuracy, and in some cases it performs better. In terms of speed our method is more than 25 times faster.
在过去十年中，已经提出了几种从磁共振图像中提取人类大脑皮层的方法。比较这些方法的研究很少。在本研究中，我们将一种最新的皮层提取方法与近年来在科学界广泛应用的FreeSurfer进行比较。使用从原始脑部扫描提取的表面生成的逼真模型进行比较。将重建表面的几何精度与从原始扫描中提取的表面进行比较。我们发现，我们的方法在精度方面与FreeSurfer相当，并且在某些情况下表现更好。在速度方面，我们的方法快25倍以上。
