医学成像系统的X-CT图像仿真研究，sheep-logon模型的重建，可用不同滤波器-Medical Imaging System X-CT image simulation study, sheep-logon model reconstruction, can be used in different filters

在研究从投影重建图像的算法时，为了比较客观的评价各种重建算法的有效性，人们常选用公认的Sheep Logan 头模型,本文就是用CT重建的理论模型，希望对大家有用-In the study from the projection image reconstruction algorithm, in order to more objective evaluation of the effectiveness of the various reconstruction algorithms, it
