We introduce a general iterative scheme for angle-limited image reconstruction based on Landwebet＇s method. We derive a representation formula for this scheme and consequently establish its convergence conditions. Ou...

Many imaging systems can be modeled by the following linear system of equations Ax=b,(1) where the observed data is b=(b^1...b^M)~T∈K^M and the image is x=(x_1…x_N)~T∈K^N.The number field K can be the reals R or th...
