Abstract
Diffusion tensor magnetic resonance imaging (DT-MRI) is a technique used to measure the anistropic diffusion properties of the water molecules in the organism. And this technique has been utilized for the diagnosis of the diseases of brain as like a cerebral infarction, a brain tumor, and variable cases. On the other hand, the dissection is the only way to obtain the visible information of the neural pathway in the brain white matter with the exception of DT-MRI. The visualization technique called "tractography" allows the user to visualize the neural pathway from DT-MRI data that needs to set of the starting point and the end point of a pathway. These points have been set by user's medical intention and there has been no the other guideline. So, we calculated isotropic region in tensor field by using the DT-MRI data set, and proposed the technique which made the visible seed area information of neural pathways. In this paper, the method of the isotropic area computation from the DT-MRI data set and the flow of neural pathway of specified region ware shown with the suitable example.
