Lytvyn // Advanced Computer Information Technologies : 9th International Conference, 5-7 June 2019. – Ceske Budejovice, CZECH REPUBLIC. – P. 125–128.http://openarchive.nure.ua/handle/document/9457A method for calculating Fourier coefficients of functions of three variables using tomograms is proposed and investigated. Earlier Lytvyn O.M. proposed and introduced the method of calculating Fourier coefficients of the function of two variables using integrals of this function along a given system of direct. It is believed that these integrals - projections or projection data arrive from a computer tomograph.en3D Fourier coefficientstomogramscomputer tomographyreconstructionimagediscontinuous splinesum FourierThesis
