Abstract

A method is disclosed for calculating an MR image of a target layer from an examination object, wherein the MR image is calculated using iterative reconstruction. In at least one embodiment, the method includes: acquiring MR data from an initial layer of the examination object, determining information produced by the examination object from the acquired MR data of the initial layer, determining a penalty term from the information produced by the examination object, and performing the iterative reconstruction of the MR image for the target layer taking into account the determined penalty term.
