Problems of realization [Elektronische Daten] [M. Agafonov, O. Sharova] Three-dimensional (3D) Doppler tomography is used to study the motions of gas flows in interacting stellar binary systems. This is achieved by applying a reconstruction method developed for few projections tomography, sometimes referred to as the radioastronomical approach (RA). An analysis of the geometry of the spatial arrangement of the aspects during the reconstruction of 3D tomograms using onedimensional profiles without the intermediate stage of constructing two-dimensional sections is presented. A method for estimating possibilities for reconstructing 3D tomograms based on the appearance of the summarized transfer function is proposed and justified. The influence of the inclination of the system on the resolutions along the main axes is considered. The number of aspects required to achieve a quality of the recontruction comparable to 2D versions is estimated. A comparative analysis of possible distortions of 2D and 3D Doppler tomograms in the presence of flow motions extending beyond the orbital plane is carried out. The analysis indicates the advantages of the 3D method. A summary of first observational results taking into account the velocity component perpendicular to the orbital plane of the binary system, V z , is presented.
