Understanding of the relationship between the structures and function of a surrounding brain tumor from magnetic resonance (MR) images is especially important procedure for determining the surgical trajectory in neurosurgery. Therefore, this study proposed the novel computer-based approaches that extract the 3D brain area, and determine the position of central sulcus that is located at the boundary between the frontal lobe (motor areas) and the parietal lobe (somesthetic areas) and is one of the most important anatomical landmarks, from MR images in patients with brain tumor. Moreover, this study developed the three-dimensional visualization system for supporting the neurosurgical planning.
