DTI Validation Telephone Conferences 2008

Tuesday January 22, 2008 - 11:00 am EST

• Nathan has posted both a 6 gradient direction phantom and a helical phantom that simulates a 60 gradient DWI acquisition mirrors the MIND Reliability dataset. Both are now available on the BIRN portal along with a document with a description of the different files present and how to use them is in the phantom directories:

/home/Projects/NAMIC_DTI_VALIDITY__0074/Data/helix_phantom_NAMIC_DTI_validity/

Both are in analyze format. Nathan is working to transform them into nrrd format, any help would be gratefully appreciated.

• Once they are in nrrd format, Sonia will generate the Regions of Interest and post those ASAP.

• Nathan is creating a wiki page with complete description of the phantom methods and link to download the binary.

• Jim Fallon has has accepted an invitation to work with the Clinical team (Randy and Marek) to define and generate the additional ROIs and neuroanatomical landmarks for the tracts that we agreed upon at the AHM. They will be working together on Friday Feb 1 in Boston and will report progress on next T-con.

ACTION PLAN:

All sites download the new phantom data (in nrrd format w/ROIs) on Monday and run your tractography algorithm on it before next Tuesday's T-con. Use this email list to work out any logistical problems.
