【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。
[Abstract]:In order to solve the problem of complex contour trajectory generation and low delamination efficiency in rapid prototyping of artificial bone tissue, a method of simplifying delamination process of triangulation model is proposed. The moving cubic block (MCC) algorithm is used to reconstruct medical image sequences. Grouping the triangular set according to the sequence of the reconstruction process, Then the edge tracing method is used to calculate the intersection contour data between the tangent plane and its corresponding triangular array. The simplified delamination efficiency is increased by an average of 4.65 compared with the delamination of the triangular mesh file (STL) model. The experimental results show that, The proposed method can directly generate contour data for 3D printing from medical image sequences of human bone tissue, thus realizing rapid prototyping of bone tissue.
