On the Bias of Finite-View Interior Tomography Using Piecewise-Constant and Non-Negativity Constraints
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...
