Using the method of water diffusion, the DWI (Diffusion Weighted Imaging), is one of the advances in clinical research of human brain. It can help neurosurgery to avoid the different kind of risks, for instance, disability of walking, talking, moving the arms, and so on. Human brain research in this direction makes possible to make tumour surgery using the DTI (Diffusion Tensor Imaging) mapping. The experiments done with phantom give us the histograms which shows the results in form of homogeneous signals in different areas of the phantom which means that human resources can be replaced with phantom and experiments done with it. This advantage gives us reason to develop this approach further.
