Diffusion Tensor Imaging (DTI), which is the magnetic resonance technology, is applied widely, especially in analyzing the brain function and disease. DTI is a four dimensional image with the principle of diffusion of water molecules, which based on the diffusion characteristic of water. In DTI, each voxel has its own value and orientation, which result in the track of movement of water molecules by the FACT algorithm. It is the tracking of brain white matter fiber, while the tractography is the tracking image of neural fiber bundles according to the principle. All images running are big data processing. The tractrography is important for analyzing the function of brain, creating the brain connectivity and analyzing neuroimage with disease. The paper mainly shows the procedure of data processing by registration that has existed in some researches. However, there is a significant comparison with nonlinear-registration and linear-registration in the paper.
