XNAT and NA-MIC Kit
NA-MIC needs:
• Improved management of ‘local’ image data
• Integration with Slicer and Batchmake
• Data sharing with collaborators

XNAT and NA-MIC Kit
XNAT solution:
• Desktop XNAT that delivers basic XNAT functionality
• Push and pull data from ‘central’ XNAT repositories via web services
• Integration with Slicer and Batchmake via XCEDE XML
• Data sharing via lightweight web services

Recap of MGH contributions
• QDEC: GUI for group analysis of Freesurfer-processed subject data
• Combined volumetric and surface (CVS) registration

“Does the correlation between cortical thickness and age differ from zero?”

CVS registration
• Surface-based (2D) registration aligns cortical folds, but doesn’t apply to non-cortical structures.
• Volumetric (3D) registration applies to the entire brain but doesn’t align cortical folds.
• Solution: integrate them!
