In the paper two new iterative algorithms of a few-view fan-beam tomography are investigated. In numerical experiment comparison of Gerchberg-Papoulis algorithm and a method of Neumann decomposition of the inverse X-ray fan-beam transform operator for the first time is provided. Accuracy characteristics of both algorithms depending on measurements random noise are shown.
