Investigation on film characteristics for hybrid processing X-ray tomography
In this paper, requirements on recording sinogram in hybrid optical digital processing X-ray tomography are analysed. The method of correcting sinogram data is described. We have investigated the effect of film granularity on the noise of reconstructed images,,have derived an expression of signal-to-noise ratio. Finally the experimental results for reconstructed images are given.
