Tomography is about reconstructing an nD object from its (n-1)D projections. This discipline addresses many questions to which research tries to provide answers. In this work, we are interested to three aspects: 1) the 2D image reconstruction from projections in a rarely studies framework that is the point sources; 2) the uniqueness of this reconstruction; 3) estimating information about an object without going through the step of reconstructing its image. To approach the problem of tomographic reconstruction for the class of convex sets, we define a new class of sets having properties of convexity called quadrant convexity for point sources. After a study of this new class of sets, we show that it presents strong links with the class of co...
