Method for generating a series of magnetic resonance images with cross-frame iterative reconstruction

Abstract

The invention relates to a method for generating a series of magnetic resonance images from an MR bin series obtained by means of an MRI measurement, wherein the MR bin series comprises a plurality of bin frames (f1, f2, f3) with determined MR data, wherein at least one bin frame is undersampled, i.e., has missing MR data in addition to the determined MR data, wherein the bin frames differ by the value of x prespecified parameters (x=1 or greater) under which the MR data were determined, comprising: a) calculating an n-dimensional preliminary reconstruction kernel from preliminary reference data of a reference frame; b) determining preliminary reconstruction frames by reconstruction of the MR data missing in the MR bin series by means of the preliminary reconstruction kernel; c) calculating an n+x-dimensional reconstruction kernel by calculation from the MR data of the preliminary reconstruction frames, wherein MR data of different preliminary reconstruction frames are used for the calculation of the n+x-dimensional reconstruction kernel; d) determining further reconstruction frames by reconstructing the data missing in the bin frames by means of the n+x-dimensional reconstruction kernel; e) generating n-dimensional magnetic resonance images from the reconstruction frames determined in step (d).
