However, MR imaging is impossible to understand the brain surface structure selectively on 3-D viewer. Therefore, the radiological technicians are visualizing the brain surface by partial removal and adjustment the threshold to the MRI data. But even the radiological technicians who were familiar with the work take time to visualize. In this paper, we propose a visualization of brain surface in the MR images for “Reduce working time“ and “present the structure of the brain surface to doctors clearly“.}, title = {頭部MR画像の構造的特徴を用いた脳表可視化法}, year = {2012} }
