Illustration of the look-up table J. The Gaussian coefficients placed on the image are stored in a vector of size \(N_g\) (top). Each coefficient point (indexed in \([0, N_g]\)) is projected on at most \(N_p\) positions in the sinogram. For each \(i \in [0, N_g]\), the structure \(J[i] = \left\{ J_{i,0}, \, J_{i,1}, \, \ldots \right\}\) (bottom) contains the list of the sinogram positions hit by projection of i. For example, the Gaussian coefficient number 0 is projected on sinogram positions \(J_{0, 0}, \, J_{0, 1} \, \ldots\)
