Abstract :
A simple approach for cross-section reconstruction with a fan-beam scanning geometry is discussed. The scanner and the radiation beams are set up in such a way that the projection data can be rearranged and considered as if they were generated from the conventional parallel-beam configuration. The convolution algorithm is used for the cross-section reconstruction of synthetic patterns. Combarisons are made between the fan-beam and parallel-beam geometries.
