| Abstract: | Filter back-projection (FBP) algorithms are available and extensively used methods for tomography. In this paper, we prove the convergence of FBP algorithms at any continuous point of image function, in L 2-norm and L 1-norm under the certain assumptions of image and window functions of FBP algorithms. |
