Abstract

Aiming at the problem of artifacts in the direct back-projection reconstruction algorithm of industrial CT, this article first uses Radon transform to obtain projection data, and then obtains the original function of the industrial CT image function through inverse Fourier transform, and performs convolution operation on the original function. Use the selection property of Dirac function to get the reconstructed image of industrial CT. The method in this paper can reduce a Fourier transform operation. The simulation results show that the method in this paper can effectively improve the blooming phenomenon of the tomogram reconstructed by direct back projection, and the reconstructed tomographic image is better.
