This page serves as a central point documenting the activities in Diffension Tensor Imaging Research within NAMIC.

ITK Data Structure for DT Pixels and Images

Given that the itk::Image class is templated over pixel type and dimension, we simply need to define a pixel type appropriate for representing Diffusion Tensor data. The following pages describe a possible implementation based on the guidelines provided in

• Pixel type
• Image type

Unified format for Input Output of DWI and DTI structured data:

• NRRD header specs for DWI and DTI data
• DICOM support for DWI and DTI
• IO specs for DTI Tensor data
• IO specs for DTI Fiber data

Processing NA-MIC DTI

• Instructions for working with Dartmouth DTI data in Slicer 2.5 Slicer:DTMRI.

Scan Protocols

Each investigator site has optimized local DTI acquisition protocols that represent the "best practices" for prospective data collection (not always the same protocols used retrospecively, but enabled by new pulse sequences and advanced scanners)

• UCI_DTI_Protocol
• Dartmouth_DTI_Protocol
• HarvardVA_DTI_Protocol
• MGH_DTI_Protocol
