Informatics tools & services for NA-MIC Dan Marcus Neuroinformatics Research Group Washington University
Overview • Introduction to the Neuroinformatics Research Group (NRG) • Introduction to XNAT • New XNAT features • XNAT and NA-MIC Kit • XNAT Central and DBPs
Introduction to NRG • NRG Neuroimaging Laboratories Mallinckrodt Institute of Radiology Washington University School of Medicine • Neuroinformatics software (XNAT is our flagship product) • Data & analysis centers (ADRC, BIRN, Brainscape, XNAT Central, etc.) • http://nrg.wustl.edu
Introduction to NRG Mohana Ramaratnam, Dan Marcus, Tim Olsen, Kevin Archie, Misha Milchenko (not pictured)
Introduction to XNAT • Informatics platform for managing biomedical imaging & related data • File repository for image data • Relational database for metadata and non-image measures • User interface tools • Auxiliary services (e.g. DICOM, FTP) • http://www.xnat.org
Introduction to XNAT • XNAT 1.3 available at www.xnat.org • XNAT 1.4 beta available from CVS repository at http://nrg.wustl.edu/viewvc (install instructions posted to google group http://groups.google.com/group/xnat_discussion). • XNAT 1.4 production scheduled for March release • XNAT 2.0 in conceptual stage
Example XNAT deployments www.brainscape.org central.xnat.org
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
XNAT and NA-MIC Kit Osirix • Local database • Integration with viewer & processing
XNAT and NA-MIC Kit Flickr • Tags • Sets • API
XNAT Central & NA-MIC DBPs • Reference data • Data from studies in pub. database • Collaboration data • Personal data
XNAT/NA-MIC bliss Please seek us out for discussion!
Recap of MGH contributions • QDEC: GUI for group analysis of Freesurfer-processed subject data • Combined volumetric and surface (CVS) registration
QDEC GUI for group analysis “Does the correlation between cortical thickness and age differ from zero?” http://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/QdecGroupAnalysis
Template HAMMER CVS FLIRT 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!
