Abstract：In this paper, we propose a fast ART algorithm based on block iteration.Compared with conventional ART algorithm, our algorithm converges fast and does not require the storage of large projectionmatrix. So it is capable of reconstructing moderate or large image.It is also applicable for parallel-ray or fan-ray projections, or the projections collected at a series arbitrary sampled angles and sampled radii. The images reconstructed by our algorithm with real CT data shows a good quality, high resolution and slight artifacts.
