The Problem of Reconstructing Objects from Projections as an Inverse Problem in Scattering Theory ofroved that the Heisenberg operator is a multiplication operator, and that it is a one-to-one mapping from the positive cone .(ℝ.×S. onto itself. The inverse problem can be solved by the inverse Radon transformation formula.

Generalized Radon Transformationslues. His paper stimulated several further investigations which achieved further reconstruction formulas; e.g. see F. John and . These results are the theoretical basis of most of the algorithms for reconstruction of density functions from projections which are used in computerized tomography.

Approximation of the Radon Transform from Samples in Limited Range. In order to use the fast reconstruction algorithms approximations of the data in equally distributed directions are provided. The complexity of the algorithm and numerical limitations are studied, numerical experiments show the usefulness of the procedure.
