Claim 9:
10. An MR system comprising:
an MR scanner configured to scan a patient,
a sensor configured to determine a movement of the patient, and
a data processor configured for image reconstruction by a Wave-CAIPI method using iterative calibration based on the k-space lines resulting from the MR scan, the data processor configured to perform the image reconstruction comprising:
(a) performance of the image reconstruction with the Wave-CAIPI method on a basis of identical calibrated PSF subfunctions for all k-space lines when the movement does not exceed a threshold value, and
(b) when the movement does exceed the respective threshold value: provision of a number of bins corresponding to sequential value ranges of the movement in at least one motion direction, assignment of the k-space lines to the bins based on the movement during the respective acquisition of the k-space line, performance of a calibration of PSF subfunctions for at least two bins on the basis of the k-space lines assigned to said bins, and reconstruction by the Wave-CAIPI method in such a way that the PSF subfunctions associated with the assigned bins are used for the respective k-space lines.
