The classification of pairs of different substances in accordance with the degree of tomographic visibility of the interfaces between these substances is considered. The classification is performed without using tomographic information and can be considered as a prediction of the quality of the subsequent reconstruction of an unknown medium. The study is based on the solution of the problem of x-ray tomography aimed at the determination of the inner structure of an unknown medium by radiation probing. The classification involves finding the contrast coefficient and studying the character of its energy dependence. The results are illustrated by plots and tomograms obtained by computer simulation.
