Automated VOI Analysis in FDDNP PET Using Structural Warping: Validation through Classification of Alzheimer's Disease Patients
Figure 1
(a) (Left) Warping results: average of 22 subjects MRIs after linear registration only (top); average of 22 subjects after warping to common space (middle); MRI of common space subject (bottom). (b) (Right) Absolute voxel-to-voxel variance of unwarped (top) and warped (bottom) MRIs. Warping reduces average in-brain variance by 54% from linear registration alone.
