Sinogram

Theoretically it would be possible to reconstruct the original image by doing the Fourier transform of all the lines of the sinogram, in such a way to obtain the lines of F(u,v) along all the angles, and then computing the inverse Fourier transform to obtain f(x,y). Normally another process called filtered backprojection is preferred.
