 ### Dataset Summary

+This IXI2D dataset contains around 28000 2D axial slices extracted from 600 MRI images of healthy subjects. Each MRI volume was skull-stripped, white matter normalized and registered to the ['fsaverage'](https://surfer.nmr.mgh.harvard.edu/fswiki/FsAverage) template using affine transformation. The slices were automatically selected based on the fraction of the amount of brain present in the image.
