Maximum entropy image reconstruction from a few views
Shaohua Chen, Qing Wang · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2001
A new algorithm for the reconstruction of tomographic images from a few views is presented. A variable metric method is used to solve the unconstrained optimization problem that resulted from the analysis by the use of the maximum entropy formalism. The numerical simulations study the reconstruction effect on the different asymmetric functions and the stability against noise. The results show that the reconstruction accuracy is adequate.
