The purpose of this study is to develop a DWI simulator, which can generate the images for the adult human brain size models in a reasonable time. In order to shorten the computation time, we proposed three approaches based on the principle of MRI to increase simulation efficiency and succeded in improving the efficiency approximately 140,000 times. As a result, simulation time for an adult human brain size model reduced to less than one hour.
