Astrotomography deals with the investigation of the stars and the Sun reconstructing their inside structure or using special tomographical methods. As it seems to us, radioastronomy has made a great contribution to the solution of the important problem of reconstruction from few projections, which are similar to those in aperture synthesis. Here the radioastronomical approach to Few Projections Tomography is summarized. The main features are deconvolution with the introduction of the Synthesized Beam (SB) and the removal of the distortions due to the SB sidelobes influence using 2-CLEAN DSA (Determination of permissible Solutions Area) method. The method is developed exclusively on the basis of radioastronomical contributions.
