DTI-non-rigid

Goals

There are three objectives:

• Inter-Subject, Diffusion-to-Diffusion, affine registration
• Inter-Subject, Diffusion-to-Diffusion, non linear registration.
• Intra-Subject, Diffusion-to-Structural affine registration.

However, there is enough data to also test structural to structural registration as well.

Data

The following data in NRRD format for 4 cases is provided on the BIRN portal in /home/Projects/NAMIC__0003/Files/PNL/RegistrationTestCases :

• 1.5T Coronal series of contiguous spoiled gradient (SPGR) images (voxel dimensions, 0.9375x0.9375x1.5mm). (caseX_SPGR)
• 1.5T Axial series of contiguous double-echo images (Proton Density and T2 Weighted, (voxel dimensions, 0.9375x0.9375x3mm). (caseX_T2; caseX_PD)
• 1.5T Line Scan Diffusion Imaging (LSDI) scan. 6 directions, (voxel dimensions, 0.859x0.859x5mm).(caseX_DWI)
• 3T 3D FSPGR Axial, (voxel dimensions, 0.5x0.5x1mm). (caseX_SPGR_3T)
• 3T T2 Axial 2mm, (voxel dimensions, 0.859x0.859x2mm). (caseX_T2_3T)
• 3T Echo Planar Imaging (EPI) Diffusion scan, (voxel dimensions, 0.9375x0.9375x1.7mm). (caseX_DWI_3T)
