So it is available to reconstruct moderate and large image by using either parallel or divergent projection data , as well as the data collected at series arbitrary sampled angles and sampled radii . and it does not require the storage of projection matrix , compared with the conventional art . the numerical results show that mart reconstructs image with fast speed , high resolution and sligh artifacts 利用分块迭代的快速art方法,对x射线工业ct实采投影数据进行图像重建,并与fbp方法、经典art方法重建的图像进行了比较,测试结果表明:该方法重建图像精度高,伪影轻,并有较高的密度分辨率和空间分辨率,较经典art方法重建速度快。
