ABSTRACT:
As disclosed herein, in a parallel magnetic resonance imaging method core magnetization is excited in an examination volume of a magnetic resonance (MR) device by generating at least one high frequency (HF) pulse. Two or more MR signals are recorded in parallel from the examination volume via two or more receiving channels (R, S) of the MR device using an HF coil arrangement (9), which comprises a number of coil elements (15, 16) which is greater than the number of receiving channels (R, S), wherein the respective MR signal on each receiving channel (R, S) is formed by weighted superimposition of coil signals (A, B, C, D, B) of the individual coil elements (15, 16). An MR image is reconstructed from the recorded MR signals, the MR signals being combined with one another taking into account effective spatial sensitivity profiles associated with the individual receiving channels (R, S).
