IART algorithm is applicable to the linear tomography.A weighted SART algorithm is advanced by using weighted method of IART.The way of obtaining weight values and initial iterative values in iterative process of curve tomography is given in this paper.The results of simulation and concrete examples show that ac-curacy of computation and the quality of image reconstruction can be improved by weighted SART algorithm com-pared with conventional SART algorithm.
