Abstract
An antenna configuration for use in a magnetic resonance apparatus has at least two individual antennas which each include at least one conductor loop, one tuning network and one matching network, wherein the individual antennas are each combined into separate modules which are positioned on and mounted to a support body and can be removed therefrom in a non-destructive fashion, is characterized in that the individual antennas are connected to each other through decoupling elements, wherein the decoupling elements are mounted to the support body in an undetachable fashion. It is thereby possible to define individual antenna modules which can be arranged in a simple fashion around the measuring volume, are also electromagnetically decoupled from each other, and can be positioned close to the measuring volume in order to ensure that the received MRI image has a maximum, high signal-to-noise ratio.
