From the subject we take the ith patch pair {fT1(i), fT2(i)} and identify the best possible matching pairs {gT1(j), gT2(j); j ∈ Ω}. The corresponding FLAIR patches {gFL(j); j ∈ Ω} are recombined using a non-local means approach to generate the synthetic FLAIR patch f̂FL(i). The merging of all such patches generate the synthetic FLAIR f̂FL.
