摘要： In a method for magnetic resonance imaging, whereby magnetic resonance signals in a region of interest of an examination subject are generated in an examination by applying radio-frequency pulses of a first transmission field strength and the magnetic resonance signals are acquired in a spatially coded manner and allocated to volume elements of the region of interest in order to obtain one or more magnetic resonance images of the region of interest, the sensitivity of each volume element of the region of interest with respect to a modification of the first transmission field strength is determined, deviations of the first transmission field strength from a reference field strength are measured during the examination, and the magnetic resonance signals acquired in the examination are corrected on the basis of the sensitivity determined for each volume element and on the basis of the measured deviations of the first transmission field strength from the reference field strength. The method enables the implementation of fMRI measurements with high precision given fluctuating transmission field strength.

摘要： A computer-implemented method for learning a tight frame includes acquiring undersampled k-space data over a time period using an interleaved process. An average of the undersampled k-space data is determined and a reference image is generated based on the average of the undersampled k-space data. Next, a tight frame operator is determined based on the reference image. Then, a reconstructed image data is generated from the undersampled k-space data via a sparse reconstruction which utilizes the tight frame operator.
