We propose and demonstrate “brain
rejuvenation” as a method to improve accuracy of automatic segmentation of the aged
brain.
Figure 3. Worsening of atlas quality with
increased simulated brain atrophy indexed by the age of the target elderly
brain. Distance is measured with respect to the gold atlas (see Figure 1).
Figure 4. Sensitivity to simulated brain atrophy
is resolved when using brain rejuvenation (Figure 2) before FreeSurfer.
