On the bias of finite-view interior tomography using piecewise-constant and non-negativity constraints.

Gengsheng L Zeng1, Grant T Gullberg.   

Abstract

It has been widely believed that the non-negativity and the piecewise-constant constraints guarantee a unique solution to an interior tomographic problem. This letter points out that if the number of views is finite, the non-negativity and the piecewise-constant constraints do not guarantee a unique solution to an interior tomographic problem and the reconstruction could be biased by a constant polygon.
