Abstract:In the three-dimensional medical image reconstruction, Marching Cube is a more commonly used iso-surface reconstruction algorithm. We can extract any three-dimensional data of iso-surface with the algorithm. But there are large amounts of data and triangular patches required to calculate, which makes the algorithm slower. This paper uses a different scale iso-surface reconstruction theory to achieve a multi-scale Marching Cube algorithm. Through the experimental comparison, we find that the new algorithm is higher efficiency and faster than the original Marching Cube algorithm.
