IXI – Information eXtraction from Images | Cortical Volume

This dataset contains cortical volume data, computed from the T1-w images present in the original IXI dataset. Structural pre-processing was conducted using FreeSurfer 6.0, with default parameters, and includes the following steps: motion correction skull stripping removal of cerebellum and brain stem intensity correction segmentation tassellation smoothing topology correction Cortical volume was produced for 68 brain regions from the Desikan-Killiany brain atlas (34 per hemisphere, measured in mm3) The original data has been collected as part of the project: IXI – Information eXtraction from Images (EPSRC GR/S21533/02)Information and data for the original IXI dataset can be found here.
