本论文从CT图像重建原理入手, 根据迭代重建的物理意义, 从投影模型出发, 得到投影数据, 然后利用迭代算法MART 及sirt 重建出断层图像, 再与模型相比较, 从而确定各算法的优劣, 总结出如何选择合适的图像重建算法。-Iterative Algorithms in Computed Tomographic Reconstruction

The iterative method is the most widely used in the series expansion algorithm. There are many different types of iterative reconstruction methods. The most widely used research and application are algebraic reconstruction (ART), simultaneous iterati
