Visualization of a brain neural pathway by using a streamline display method

Abstract

Visualization of a brain neural pathway is considered as a very useful tool for support of the surgery planning. In this paper, we propose visualization techniques that estimate the neural pathway from DT-MRI (Diffusion Tensor Magnetic Resonance Image). We utilize vector plots, streamlines, and volume rendering. By calculating critical points, we use them as start points of streamlines. In addition, we overlay both the brain neural pathway and brain from MRI (Magnetic Resonance Image). We applied our visualization techniques into DT-MRI, and several images are shown in this paper.
