## Abstract The Radon transform __R__(__p__, ΞΈ), ΞΈβ__S__^__n__β1^, __p__ββ^1^, of a compactly supported function __f__(__x__) with support in a ball __B__~__a__~ of radius a centred at the origin is given for all \documentclass{article}\pagestyle{empty}\begin{document}$ \theta \in \mathop {S^{n - 1
The present paper deals with the computational complexity of the discrete inverse problem of reconstructing ΓΏnite point sets and more general functionals with ΓΏnite support that are accessible only through some of the values of their discrete Radon transform. It turns out that this task behaves quit
