Data Exchange

On the right is an example from the 90Mb of MR brain scan images which are available from this IBSR. Manually-guided segmentation results (shown as green outlines) are provided for some data sets along with the corresponding MR images. The MR image data is a T1-weighted 3-dimensional coronal brain scan after it has been positionally normalized. The segmentation or "outline" files are the result of semi-automated segmentation techniques which require many hours of effort by a trained expert. Even though manual segmentations cannot be considered to be 100% "ground truth", they are a good way to begin comparing automated segmentation methods.
