Analysis of influence of noise on the quality of shadow tomogram reconstruction via preliminary projection filtering

The problem of image reconstruction in the shadow tomography is discussed, the process of shadow tomogram obtaining is described, the main sources of noise are considered, evaluating characteristics of the noise signals are presented, the scanning process with taking into account of the noise is simulated, the comparison of the image reconstructed without noise, and the image reconstructed with the presence of noise are presented, it is established that the preliminary projection filtering method is effective for projections with noise.
