1. A coil unit decoupling circuit, comprising:
a first phase-shift circuit configured to be coupled to a first coil unit in a magnetic resonance system; and
a second phase-shift circuit configured to be coupled to a second coil unit in the magnetic resonance system,
wherein the coil unit decoupling circuit is configured to separate, using a distribution characteristic of a spatial quadrature field between the first coil unit and the second coil unit, a Helmholtz signal and an anti-Helmholtz signal from signals received from the first coil unit and the second coil unit via the first phase-shift circuit and the second phase-shift circuit, respectively, to electromagnetically decouple the first coil unit and the second coil unit from one another.
