Abstract
In a method for the selection of a local antenna from among a number of local antennas that are spatially distributed in a diagnostic magnetic resonance apparatus, a target volume for the imaging is excited to emit magnetic resonance signals. The magnetic resonance signals are received with the local antennas. A characteristic quantity in the magnetic resonance signals respectively received by the local antennas is determined, this characteristic, for each antenna, quantity representing a measure for the distance of the target region from that local antenna. The local antenna is selected that is located closest to the target region, from among the multiple local antennas, dependent on the characteristic quantity.
