ABSTRACT:
An MR apparatus includes an MR coil system of the so-called bird cage type which operates in a degenerate mode of operation in which all resonance modes and all resonance frequencies coincide. It has been found that the individual meshes of the MR coil system are then decoupled from one another, thus enabling operation as a coil array, the individual MR signals being processed in separate processing channels so as to form MR sub-images which can be combined in a reconstruction unit so as to form an MR overall image having an improved signal-to-noise ratio.
