ABSTRACT:
In a method and apparatus for magnetic resonance imaging based on a partially parallel acquisition (PPA) reconstruction technique, a number of partial k-space data sets are acquired with a number of component coils, the totality of the partial data sets forming a complete k-space data set, the respective coil sensitivity of each component coil is determined based on at least one part of the complete k-space data set, any partial k-space data set is transformed via a PPA reconstruction technique dependent on the determined coil sensitivities, and the transformed partial data sets are superimposed to obtain a low-artifact image data set.
