Research Abstract

We produced the method to remove the unwished signal and noise that came from others than brain automatically. This method succeeded that the calculation accuracy increased even if the subject had large mass or large ventricle.
On the other hand, we had developed the method to discriminate the high FA structure such as corpus callosum and pyramidal tract. The novel proposed method used all raw images of the diffusion tensor imaging. It had the same accuracy in the structure with high FA value. However, it permitted to discriminate the low and moderate FA structure which had distinguishing fiber structures.
