Abstract
The present disclosure is directed to a coil unit decoupling apparatus and a magnetic resonance system. The apparatus is connected to a first coil unit and a second coil unit in a magnetic resonance system, and is configured to separate, by 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, so as to implement decoupling between the first coil unit and the second coil unit. This facilitates the complexity of decoupling coil units being reduced.

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.
