A receiving coil, comprising:
- at least one coil element that can simultaneously receive a magnetic resonance (MR) signal having a plurality of different frequencies, wherein:
- a resonance structure for the plurality of different frequencies is provided disposed in a single plane in the at least one coil element,
- the at least one coil element of the receiving coil is configured to receive the MR signal emitted from an object in response to an excitation pulse applied to the object, the object being placed in a static magnetic field;
- and
- the MR signal has the plurality of different frequencies depending on a position of the object in the static magnetic field having a non-uniform static magnetic field distribution.
