摘　　要：给出一种血管三维重建的新方法。该方法根据广义锥理论,可以由多幅血管的微米级连续切片图像,通过计算投影图像和中轴线,得到该血管直径和血管中轴线的三维坐标,从而给出血管的三视图投影图像,并实现血管的三维重建。并将问题的数学解法通过计算机程序实现。本文的独创性在于引入广义锥理论给出了实用的算法,并对计算精度进行了细致的改进。实验证明本文的方法实用、简便、准确,便于在实用工作中采用。In this paper a new 3D construction method for blood vessel was presented based on generalized cylinder theory. 3D mathematical algorithm has beengiven by computing 3D perspective projection from a series of images ofmicrometre-level slice. programming was realized for 3D reconstruction ofblood vessel. The creative oponion lies in the practical algorithm deducedfrom generalized cylinder theory, as well as the delicated improvement oncomputing precision. This method has been proved practical, convenient andaccurate.
