Abstract: In the paper is shown that results of C(N)D-recovery of derivatives by the value at the point with using just only one relationships $\left\| f\right\| _{W_2^r (0,1)^s } \asymp \left\| Rf\right\| _{W_2^{r+\frac{s-1}{2} } (0,1)^s} $ implies Radon's scanning algorithm of an arbitrary open (not necessarily connected) bounded set, which is optimal among the all computational aggregates, constructed by arbitrary linear numerical information from the considered object with indicating the boundaries of the computational error, not affecting the final result.} \keywords{Keywords}{Radon transform, Sobolev space, Computational (numerical) diameter (C(N)D), recovery by accurate and inaccurate information, computational unit, discrepancy, uniformly distributed grids, Korobov grids, optimal coefficients.
