| Abstract: | In order to reduce the number of triangular patches in surface rendering, save space and improve reconstruction results, a contour connecting method based on interzone line was proposed in this paper. This connecting method needed to resample with angle and generate secondary resampling points with geometric methods. And resampling points corresponded with each other. Tissue surfaces were reconstructed with quadrilateral patches and 3D reconstruction was realized. In experimental simulation, a series of head CT images were researched. The simulation analysis shows that to resample the contour line and use quadrilateral patches instead of triangular ones, the number of patches is reduced and the storage space is saved. The reconstruction time is short and the reconstruction efficiency is high. |
