White matter tract atlas has gained interests in the neuroscience community because it provides 3D anatomy of white matter fiber pathways in the human brain. Recently, we constructed a diffusion spectrum imaging (DSI) template (NTU-DSI-122) from 122 healthy adults DSI datasets. Difficult fiber pathways which are of small sizes or have frequent crossings with other fiber tracts were reconstructed on the template. The tract atlas can be used to understand the geometric features of the white matter fiber pathways. Moreover, It allows us to implement a template-based approach that enables the microstructural integrity of the tracts in the human brain.
