摘要:
In a method and magnetic resonance (MR) apparatus for combining MR signals that were acquired with different acquisition coils from a region of an examination subject at least two MR signals that are based on MR signals acquired with at least two different acquisition coils are provided to a processor. Due to the spatially differing arrangement of the respective acquisition coils, the at least two MR signals image the region of the examination subject with different sensitivity profiles. The provided MR signals are combined, such that unwanted MR signal portions are suppressed, to form a combined MR signal with the suppression of unwanted MR signal portions being implemented by MR signal portions that were acquired with an acquisition coil that detects the unwanted MR signal portions with increased sensitivity in comparison to other acquisition coils being weighted less in the combined MR signal than other MR signal portions.
