1 Imaging Capacities The ability to collect imaging data from different sites The ability to share imaging data from different sites The ability to analyze imaging data from different sites The ability to combine images at different scales Types of data Structural imaging Functional imaging Arterial Spin Labeling Diffusion Weighted imaging Mouse models

2 2003 Every parameter matters… Same subject, same slice, different scanners 2007 Can MR Data Be Combined Across Sites?

3 Multi-site fMRI: 3T scanners BWHDuke MGHYale

4 Warping Due to Imaging Gradient Imperfections Overview License-free code that unwarps images and decreases intensity variability. Currently supports GE and Siemens gradient sets. (Working on Philips…)

5 Application – Cortical Boundaries Siemens GE CORTICAL ESTIMATES: NO DISTORTION CORRECTION Same Subject Co-registered CORTICAL ESTIMATES: DISTORTION CORRECTION Lesson: Head placement is important!

6 BIRN Covers Entire Data Flow Data Acquisition Visualize Data Grid Local DB Remote DB Database Management Integrate Share Discover Analyze Pipeline Workbench Workflows Data Processing

7 Mouse BIRN Atlasing Toolkit (MBAT) search workspace keyword search & query term search search result table cart move data between workspaces hover to show thumbnail image

8 viewer workspace display data from online DB & local image data and atlases in a single viewer hierarchy viewer- read OBO format online data from CCDB & GenSat
