- Slicer
- Slicer26 should be able to read NRRD DWIs now
- doDTI gives you mean FA, would be nice to display this in Slicer somewhere
- New protocol: scanning today?
- required that a licensed MD approve every scan
- sequence will be DICOM files, probably same format as before, same procedure for downloading
- Marek meeting with Nan-Quei at 1:30 today at the SPL to talk about the protocol
- Will try multiple scans varying b-value and number of directions
- Will try 750 and 1000 with minimum of 32 directions; also try 50 directions
- Anterior Commissure
- would be nice to have an extra scalar map with orientation overlayed with the output of this method
- Gordon will finish creating these maps and send to Sylvain
- Cingulum Bundle histograms of FA/Mode
- note that people tend to overestimate how linear the ROI will be.. mostly orthotropic
- now that we know that anisotropy is a bi-variate quantity, still need to answer the question about how to do statistics on this; non-parametric tests?
- would be helpful to have comparison of different white matter ROIs, plotted in this space
- Corpus callosum, cingulum bundle, STG white matter, STG gray matter, CSF; these ROIs will be sent to Gordon
- Kang Uk - problem with tensor coregistration?
- script was updated by Mattan in slicer-nightly, but still doesn't seem to be working
- will try a basic co-registration of two tensor sets in the same direction
