  • Abstract
    The author gives a reformation of Grangeat´s result on how to compute 3-D Radon data from cone-beam projections. He then proposes to recover detector plane line integrals and derivatives of Radon data by a technique which is the 2-D direct Fourier method in reverse. The computation complexity for an N3 object is thereby reduced from O(N4) to O(N3 log N)
