Abstract

For material characterization, first and second measured MRI data (20, 23, 26) representing an object (6) and corresponding first and second sequence descriptions (21, 24, 27) are received. For each iteration, first and second simulated MRI data (22, 25, 28) is generated according to the sequence descriptions (21, 24, 27) based on a model (29) comprising model values for at least one material parameter. An error (31) is determined, which depends on a deviation of the simulated MRI data (22, 25, 28) from the measured MRI data (20, 23, 26). The model (29) is adapted depending on the error (31). For an initial iteration, the model (29) corresponds to an initial model (29) and otherwise it corresponds to the adapted model (29) of the preceding iteration. The quantitative material characterization is determined depending on the adapted model (29) of a final iteration of the two or more iterations.
