Abstract :
In fan beam computerized tomography, a crosschannel noise problem arises due to the scattering of photons from one path into another. This paper describes the effect of these scattered photons on the reconstructed image and gives an estimate of the quantities of scatter which are acceptable without serious degradation of the reconstruction.
