Abstract
The author of the article investigated one algorithm for a solution of a tomography problem, based on calculation of indicator of inhomogeneity [1], that recovers boundaries of different includions of the domain. Different authors, used special programs [3], constructed internal structure of some domain, ingoing radiation flows and calculated outgoing radiation flows. Used this data and indicator of inhomogeneity, they solved the problem of tomography and reconstructed internal structure of the domain. It was true, that indicator performed very well, when the condition of visibility [1] was satisfied. But in that cases, when the boundaries were close to poor invisible [1], the tomographic images of the domain were not good. Used this information the author had to improve investigated indicator. Some images were improved. Some modifications are presented in this article.
