Surface rendering is a useful method in 3D visualization of brain MR images.Especially when the segmented result of MR images is given in advance, discretized marching cubes (DiscMC) algorithm can be easily utilized.However, the complexity of cerebral surface increases the number of triangles produced by DiscMC and thus, the computation time becomes an impediment to real-time 3D rendering.In order to speed up the 3D rendering, we propose a modified DiscMC table to reduce the number of triangles DiscMC.The proposed method reduces the number of triangles by 30% without loss in brain MR image quality.
