Abstract: The algebraic reconstruction technique (ART) is proposed to reconstruct image from incomplete projection data.Using the PC cluster system,we accelerate the ART reconstruction process based on dispatching projection angle evenly to each CPU and then average all the results.Experiments show that the speedup factor is roughly equal to the number of CPU's used appropriately and that the image quality is better than those by the classical serial algorithm.
