Preprocessing and Discrete Tomographic Reconstruction in NeutronRadiographyZoltán Kiss, Lajos Rodek, László Ruskó, Attila Kuba and Márton BalaskóNeutron tomography can be used and applied for non-destructive specimen examination.It is typical that the projection images are noisy. This effect can be reduced by preprocessing.Since projection acquisition is a time consuming and costly procedure, the goal is to performthe reconstruction using only a few projections. However, mathematically not all the classes offunctions can be reconstructed from a few projections. The discrete tomography seems to bea suitable tool to solve this problem by the assumption, that the object consists of only a fewknown materials.The applied preprocessing steps are introduced, and a discrete tomographic reconstructionmethod is presented, which considers and solves the problem as a combinatorial optimizationtask. Their efficiency is demonstrated using phantom and real input data.71
