Abstract: Concerning the problems that coutour complex path trajectory generation and low slicing efficiency in rapid prototyping of artificial bone tissue, a method to simplify the slicing process of triangle mesh was proposed in this paper. The medical image sequences were reconstructed by the Marching Cubes (MC) algorithm, the triangle meshes were grouped into triangle arrays according to the order of the reconstruction process. And then, the intersection points between the slice plane and the triangle array were calculated by edge tracking. It was found that the slicing efficiency of simplified process was increased by 4.65% on average compared with the triangular mesh STereoLithography (STL) model. The experimental results indicate that the proposed method can generate contour data used for 3D printing directly from medical image sequences of human bone tissu, so as to realize the rapid prototyping of bone tissue.

摘要: 针对人工骨组织快速成型中轮廓线轨迹生成复杂、分层效率低的问题,提出了一种简化三角片模型分层过程的方法。应用移动立方块(MC)算法对医学图像序列进行面绘制重建,根据重建过程的顺序对三角片集合分组,然后采用对边追踪的方法计算切平面与其对应三角片数组的交点轮廓线数据。简化后的分层效率相对于三角网格文件(STL)模型分层平均提高了4.65%。实验结果表明,所提方法可以直接从人体骨组织医学图像序列生成可供3D打印的轮廓线数据,从而实现骨组织的快速成型。
