A method for reconstructing single-slice image data sets from k-space measured data sets that have been acquired simultaneously from at least two slices from an examination object. The method includes an iterative modification and hence an optimization of the underlying k-space trajectories in the reconstruction of individual image data sets from collapsed measured data sets acquired from a plurality of slices and hence a retrospective reduction of interference in the individual image data sets that are obtained.

The disclosure relates to a method for generating a B.sub.0 map for a magnetic resonance examination of an examination subject, a magnetic resonance device, and a computer program product for executing the method. The method provides for the application of at least two preparatory RF pulses during a preparatory stage and at least one readout RF pulse during an acquisition stage. At least one stimulated echo signal is acquired after the readout RF pulse. A B.sub.0 map that shows the actual spatial distribution of the magnetic field strength of the main magnetic field is derived from the at least one acquired FID echo signal and the at least one acquired stimulated echo signal.

Disclosed herein is a medical system comprising a memory storing machine executable instructions. The medical system further comprises a computational system. The execution of the machine executable instructions causes the computational system to: receive k-space data descriptive of a region of interest of a subject, wherein the k-space data is acquired using a magnetic resonance fingerprinting pulse sequence configured for encoding chemical shifts; receive fat peak weights descriptive of a magnetic resonance fat spectrum, wherein the fat peak weights are matched to a pulse train of the magnetic resonance fingerprinting pulse sequence; and reconstruct a quantitative magnetic resonance image from the k-space data and the fat peak weighs.

Disclosed herein is a medical system (100, 300, 500) comprising: a memory (110) storing machine executable instructions (120) and a processor (104). Execution of the machine executable instructions causes the processor to: receive (200) magnetic resonance imaging data (122), wherein the magnetic resonance imaging data has a spiral k-space sampling pattern; reconstruct (202) at least one preliminary magnetic resonance image (124) from the magnetic resonance imaging data; construct (204) a first set of equations comprising (130) each of the at least one preliminary magnetic resonance image being equal to an image transformation of at least one clinical image, wherein the image transformation makes use of a first spatially dependent kernel for each of the at least one clinical image (126, 126′, 126″); construct (206) a second set of equations (134) comprising at least one regularization matrix (132, 132′, 132″) times the at least one clinical image; and numerically (208) solve the first set of equations and the second set of equations simultaneously for the at least one clinical image.

The disclosure relates to techniques for acquiring measured data that has been recorded simultaneously via a magnetic resonance facility from at least two slices from an examination object comprising at least two different spin types. The techniques includes selecting a desired simultaneous recording of measured data from at least two slices in which during recording phases that generate field of view shifts have been imprinted, selecting a compensation factor to compensate for interference signals caused by the different spin types, determining a compensation phase for the phases to be imprinted in the desired recording as a function of the compensation factor, and carrying out the desired recording of measured data and/or reconstruction of image data from the measured data by applying the compensation phase that has been determined to the respective phases to be imprinted.
