Abstract
In computed tomography, the reprojection from provisionally reconstructed image is often needed, and a few kinds of algorithms have been usedfor that purpose. But no conventional reprojection algorithm corresponds to the Radon transform in the continuous field, and the analytically accurate reprojection algorithm has been desirable. This paper proposes a reprojection algorithm based on the Radon transform in the continuous field, and the superiority of the newly proposed algorithm to the conventional ones have been proved through the computer simulation.
