Inverse problems with inexact forward operator: iterative regularization and application in dynamic imaging

SE Blanke, BN Hahn, A Wald - Inverse Problems, 2020 - iopscience.iop.org
The classic regularization theory for solving inverse problems is built on the assumption that
the forward operator perfectly represents the underlying physical model of the data …
