Diffusion weighted image (DWI), based on which a diffusion tensor image (DTI) is calculated, is affected by several artifacts and noise that complicate the analysis and interpretation of DTI. As DWI is multi-boundary in nature, to get accurate boundary signals of DWI is particularly important. A new...
