Operators iterlineation (interflatation) restore functions (probably, approximately) n variables on their known traces on the given system of lines (surfaces). That is integrals from such oparators the specified lines or surfaces (linear integrals) are equaled to integrals from the most restored function. This idea underlies methods of the decision of flat and spatial problems of the Radon computer tomography which is advanced in the given research.
