Interfacing processing and visualization tools: FIPS to Slicer3 and the QueryAtlas
Goals for 3D Slicer fBIRN Query Atlas • Rich Data Exploration Environment • Functional / Structural 3D Visualization • Morphometry Results: Surface/Volume ROIs • Access to Experiment Data (HID) • Subject ID, Demographics, Diagnoses… • Acquisition Paradigms • Analysis Design, Contrasts… • Data Analysis Provenance • Scientific Literature and Web Searches • Data Loaded by Queries • BIRN DBs • Local Cache / Analysis Directories
Versions of QueryAtlas • First Version in Slicer2 • Multiple ROI Search Terms • Web Targets • UMLS, Talaraich, FreeSurfer Anatomy Terms • Drawbacks • Awkward Programming Interface • Slow Response to Selections • Not Tightly Integrated with Application • No Link to BIRN Study Databases • Now Being Reimplemented in Slicer3 • New Programming Model • Better Performance • Explicit Links to BIRN Informatics
Overall Pipeline HID FIPS FIPS2MRML Query Atlas Local disk Visualization screenshot Tools to Streamline Retrieval of FIPS Processing Data for Visualization and Analysis
Information & Infrastructure for FIPS Users HID FIPS FIPS2MRML Query Atlas Local disk USE: • Environment Variables for FIPS FreeSurfer and Slicer • known directory structure for BIRN and FreeSurfer Data • automatically generated FIPS files (fips.database.dat, FSBIRNID.dat)
Searches based on keyword, value HID FIPS FIPS2MRML Query Atlas Local disk • User specifies search criteria • Currently returns matches for BIRN FirstLevel analysis datasets on local disk • (Same principles can be used to query HID) • Generates Slicer MRML scenes (Medical Reality Markup Language – XML description) • FIPS2MRML Included with QueryAtlas in Slicer3 Development Version
Searches based on keyword, value HID FIPS FIPS2MRML Query Atlas Local disk Visualization screenshot • Scene loaded into Slicer3 • Query Atlas used to visualize FIPS and FreeSurfer analyses: (brain.mgz, aparc+aseg.mgz, lh.pial, zstat volumes) • Query using user keywords and anatomical context • Interactive Exploration
Prototype QueryAtlas in Slicer3 • Direct Access to Anatomical Labels • Hardware Assisted Anatomy Picking • Context Menu Access • Quick Access to Searches • Build Complex Queries • Integrated with Modernized Slicer Architecture
Objectives for Next Iteration of Query Atlas • Collect and Implement User Scenarios • Integration with BIRN Databases • FIPS2MRML tie to HID, SRB • Incorporate Terms for Paradigm, Diagnosis… • Improved Ontologies • Gray and White Matter • Experiment and Subject Information • Suitable for Literature Searches • Refine Coordinate Systems • Functional / Structural • First Level / Group (linear, nonlinear, flattened) • Group Level Analysis
Timeline for QueryAtlas • Leverage Slicer3 efforts of Collaborations • NAC, NA-MIC plan for Slicer3 Release in January, 2007 • mBIRN Query Atlas with Freesurfer Interoperability in Slicer3, March 2007 • Slicer3-based fBIRN QueryAtlas release for next fBIRN Meeting, April 2007 • Identify User Scenarios at this Meeting • Determine Target Implementation Features
