| 摘 要： | 本文提出了一种由二个正交的X光投影进行解剖结构截面重建的新方法。首先由二正交投影获得等分(Equidivisor)简称ED)曲线，从ED曲线唯一地确定截面；其次将该截面用作初始截面，应用模拟退火(SimulatedAnnealing简称SA)算法对其进行变形，从而获得真正截面的最佳逼近；最后将本文算法应用于仿真图像，获得了良好的结果。

| Abstract: | The subject of this paper is to reconstruct the cross sections of anatomical structures from two orthogonal projections.Firstly, we obtain the equidivisor (ED) curve from two rothogonal projections. The cross sec tions determined by ED curve is used as an initial solution. Secondly, to find an optimal configuration, a specific algorithm of optimization algorithm based on Simulated Annealing (Abbreviation SA) is used to deform the initial solution. The method performs well on the simulated cross sections |
