Analysis of view aliasing for the generalized Radon transform in

Alexander Katsevich

In this paper we consider the generalized Radon transform in the plane. Let be a piecewise smooth function, which has a jump across a smooth curve . We…

Novel resolution analysis for the Radon transform in for functions with rough edges

Alexander Katsevich

Let be a function in , which has a jump across a smooth curve with nonzero curvature. We consider a family of functions with jumps across a fami…

Resolution of 2D reconstruction of functions with nonsmooth edges from discrete Radon transform data

Alexander Katsevich

Let be an unknown function in , and be its reconstruction from discrete Radon transform data, where is the data sampling rate. We study the resolution of…

Resolution analysis of inverting the generalized -dimensional Radon transform in from discrete data

Alexander Katsevich

Let denote the generalized Radon transform (GRT), which integrates over a family of -dimensional smooth submanifolds , $1\le…

On the spectral properties of the Hilbert transform operator on multi-intervals

Marco Bertola, Alexander Katsevich, Alexander Tovbis

Let be two multi-intervals with non-intersecting interiors. Consider the following operator $$A:\, L^2( J )\to L^2(E),\ (Af)(x) = \frac 1π\int_{ J } \frac {f(…
