SIMULTANEOUS MULTI-SLICE MAGNETIC RESONANCE IMAGING WITH IRREGULAR AND INCOMPLETE K-SPACE SAMPLING

摘要

The invention concerns a simultaneous multi-layer magnetic resonance measurement process, a corresponding magnetic resonance device (10) and a corresponding computer program product.;A procedure for measuring magnetic resonance shall be proposed at least for a group of simultaneous layers along a layer axis. A scanned frequency range is defined in a frequency space by means of a system control unit (22). A first frequency space dimension (ky) is assigned to a first phase encoded axis and a second frequency space dimension (kz) is assigned to a second phase encoded axis,where the second phase-coded axis corresponds to the stratum axis. In addition, the system control unit (22) establishes a multiple sampling scheme for each group of simultaneous layers (P). An irregular, incomplete scan of the frequency range is foreseen along the first frequency space dimension (ky) and/or second frequency space dimension (kz). In addition, a magnetic resonance measurement of at least one group of simultaneously stimulated layers along the axis of the layer shall be carried out according to the respective sub-scanning scheme for the acquisition of magnetic resonance signals.
