Reviews of Image Reconstruction from Limited-angle

In this paper,the methods and algorithms for image reconstruction from limited-angle are discussed.It belongs to incomplete-data reconstruction,since the data sufficient condition is not satisfied and exact reconstruction is technically impossible.The methods and algorithms can be classified into two categories:transform-based iterative-analytic reconstructions and series expansion-based iterative-algebraic/statistical reconstructions.Meanwhile,image reconstruction from limited-angle is equivalent to inversion of ill-posed matrix so that proper limitation conditions,a prior knowledge and regularizations play vital roles.
