Abstract

This paper presents an adaptive multigrid method used in both the forward and inverse problems. The proposed method combines adaptive mesh and multigrid solution strategy to resolve the forward problem. The accuracy and efficiency of the former forward solver are improved by incorporating the above two procedures. For image reconstruction the regularized Gauss-Newton method combined with adaptive multigrid method can improve the spatial resolution of reconstructed images. Both experimental and simulated results are presented.
