Abstract

In 3D reconstruction for CT images, the Marching Cubes (MC) algorithm is a popular used surface rendering algorithm. However, current MC algorithm has to calculate a large amount of data and triangular patches, which leads to a lower speed of the algorithm. This paper proposes an improved MC algorithm by improving the representation of voxels. By increasing the volume of voxels, the number of voxels that need to be traversed in 3D reconstruction is greatly reduced. Before the isosurface is drawn, the triangle mesh is subtracted. At the same time, in the process of calculating the equivalent points, this paper proposes to introduce smoothness and distortion coefficients to control the smoothness and distortion of the 3D reconstruction model. Simulation results show that the proposed algorithm is more efficient than the MC algorithm, and improves the real-time interaction and the controllability of smoothness and distortion.
