摘要
针对现有医学图像技术中三维模型的虚拟剖切面重建算法功能单一、不能完成复杂路径剖切面展开的缺点,提出基于空间任意标志点的剖切面重建算法。该算法可以沿三维空间中的任意路径完成虚拟剖切面展开,包括确定标志点、拟合虚拟剖切路径、重建剖切面3个部分。实验证明该算法可以得到稳定优异的重建图像,精确度较高。
This paper discusses the shortage of traditional virtual cutting surface reconstruction algorithm in medical image, which can not reconstruct a complex cutting surface. This paper proposes a virtual cutting surface reconstruction algorithm based on marked points to reconstruct a cutting surface along marked points in 3D environment. The algorithm includes marked points measure, cutting path fitting and cutting surface reconstruction. Experimental results show that the algorithm can provide good reconstruction image and high precision.
