Paper Abstract

In this paper, an interpolation method based on B-spline functions is used in image reconstruction. First, an elementary review of B-spline function interpolation theory is given. Next, the influence of the boundary conditions assumed here on the interpolation of filtered projections and also on the image reconstruction is discussed. It is shown that this boundary condition has almost no influence on the image in the central region of the image space, because the error of the interpolation decreases rapidly - indeed, by a factor of ten in shifting two pixels from the edge toward the center. The implementation results show that the computational cost for the interpolation using this algorithm is about one-tenth that of the same subjective and objective fidelity as the conventional algorithm.
