摘要：

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 which resulted from the analysis by use of the maximum ent ropy formalism. The numerical simulation is used to study the reconstruction eff ect on the different asymmetric functions. The results show that the reconstruct ion accuracy is satisfactory.
