Figure 2. Image template generation.
The structural images Si (i ∈ Γtemp) are first co-registered with their corresponding PET images Fi, and then used to construct the population-average structural image template S̄ using a deformable registration framework. The resulting mappings Ti ∘ ϕi are applied to the PET images. The deformed PET images are averaged to construct the PET image template F̄.
