为了验证锥束CT成像算法的性能，提出了使用Fortran语言编写的3D Shepp-Logan体模作为算法性能验证的参考模型，并详细介绍了3D Shepp-Logan体模的参数设置及编程方法。然后，直接加入到正投影程序中得到投影数据。最后，利用得到的投影数据进行了三维医学图像重建的仿真实验。经过实验验证，表明了使用Fortran语言编写的3D Shepp-Logan体模来验证算法性能是准确可行的。

In order to verify the performance of cone-beam CT imaging algorithm, 3D Shepp-Logan phantom produced by For-tran is presented as the reference model for algorithm performance verification, and introduces the parameter of 3D Shepp-Logan phantom and programming method detailedly. Then, we put it in the projection process directly and get the projection data. Fin-ally, simulation experiments of 3D medical image reconstruction are carried out by the projection data. After experimental veri-fication, it is shown that the performance of the algorithms verifying through 3D Shepp-Logan phantom produced by Fortran is accurate and feasible.
