''DTI Meeting Minutes: February 22, 2006''

# Tensor masking in Slicer
#* Masking in DTMRI module is too aggressive, masking out all of the skull and even some white matter; we also don't want the eyes masked out.
#* Stephan's method for masking produces the desired result, so should be replicated in Slicer
#* CF: This can be fixed next Friday (3/3/06) at 1249 Boylston; still submit as a bug report
# Bug: Tract seeding settings in DTMRI
#* Parameters under "Settings" tab are not affecting the tracts seeded from ROIs
#* Possibly due to changes made by Lauren or Gordon as they have been modifying this section recently; will talk to Lauren about it
# Cingulum Bundle
#* Raul's Sensitivity measure has been changed so that it is normalized, but has not yet been compared to previous tests
#* Marek suggested that we do a validation paper that looks at previous cingulum bundle group differences from labelmaps, and compares to fiber tracking results.
#* Currently we are losing all the fibers from the cingulum that go to the temporal lobe, probably because the slices are so thick and there is partial voluming
# Scanners
#* We are still waiting for approval for scanning, figuring out IRB forms
#* The scanners are running clinical subjects right now
#* There will eventually be a transition from long-bore to short-bore, so any new longitudinal studies should be started on the short-bore scanner; Marek noted that all DTI studies should be done on the short-bore magnet (but the scanner is smaller, so some of our subjects don't fit).
