Patent ID: 10670681

Abstract:
In a magnetic resonance apparatus and a method for generating MR image data of a subject with parallel imaging, a reference data set of the object is recorded, in which at least one partial section of the associated raw data space is completely filled with raw data according to the Nyquist condition, and an imaging data set is recorded for the generation of the MR image data on the basis of spin-echo-based signals, in which the associated raw data space is not completely recorded according to the Nyquist condition. A weighting matrix is calculated based on the reference data set, which is used to determine raw data points of the imaging data set not recorded during parallel imaging. The unrecorded raw data points of the imaging data set are calculated using the calculated weighting matrix. The reference data set is recorded with a spin-echo-based reference imaging sequence without segmentation within an imaging slice and without temporal overlap with the recording of the imaging data set, and a resolution is used in the readout direction which is lower by at least a factor of 4 than when the imaging data set is recorded.
