Despite considerable successes in a computer tomography, practical realisation tomographyc method in the form of x-ray and magntic-resonance computer tomographs is still far from an optimality. One of principal causes which confirm such statement is insufficiently proved quantity of projections (Radon data) which is used by modern x-ray computer tomographs for object restoration in the set section (i.e. the dose of radiation of object is unreasonable). The second reason contains that modern computer tomographs (magnatic-resonance and x-ray) at object restoration in the set section show on screens of displays artefacts - not structures peculiar to real object - shades, illegibilities of the image, an impregnation etc. Interflatation operators restore functions (probably approximately) from three variables on their known traces on the given system of surfaces. That is integrals from such operators on the specified surfaces are equaled to integrals from the most restored function. This idea lays in the basis of methods of the decision of a spatial problem of a computer tomography which are offered in the given research. In work the state-of-the-art review of methods of the decision of a three-dimensional problem of a computer tomography and their lacks is passed. The new method of restoration of internal structure of three-dimensional bodies which consists in use of the tomograms arriving from computer тоомграфа, and intarflatatoion operators of functions is developed. This method allows to eliminate occurrence of artefacts, illegibilities, shades and other lacks which arise at diagnostics on magnatic-resonance tomographs, to reduce a radiation dose on x-ray tomographs and to increase accuracy of diagnosing on tomographs.
