O(N/sup 2/ log N) native fan-beam tomographic reconstruction

We present a new fast backprojection algorithm for CT fan-beam reconstruction. The new algorithm operates directly on fan-beam data without prior rebinning to parallel-beam projections. The algorithm reduces the computational complexity from O(N/sup 3/) for the traditional fan-beam algorithm to O(N/...
