Abstract
The problem of estimating an unknown density from its lower dimensional projections in a limited range of views can be put in the framework of "time and band limited functions." In some instances this leads to a highly favorable and exceptional situation: the singular value decomposition of the corresponding "Finite Radon Transform" can be accomplished and the degree of illconditioning fully analyzed. The reason for this accident is poorly understood; we give a number of examples which include the cases of X-ray as well as NMR tomography.
