Claims16
A magnetic resonance (MR) coil, comprising:
- at least one antenna element, wherein the at least one antenna element comprises an expandable conductor section and an additional expandable conductor section, wherein the expandable conductor section comprises a plastic cover;
- and
- a core comprising a conductive fluid,
- wherein the at least one antenna element and the additional expandable conductor section are each configured to have a varying resistance during expansion.

The MR coil of 13, further comprising:
- a capacitance diode switched in parallel to a fixed frequency-determining capacitor of a matching network,
- wherein the capacitance diode is controlled via the control voltage to compensate for any frequency change caused by expansion.
A magnetic resonance (MR) coil, comprising:
- at least one antenna element, wherein the at least one antenna element comprises at least one expandable conductor section, wherein the at least one expandable conductor section comprises a plastic cover;
- and
- a core comprising a conductive fluid,
- wherein a reflection factor of the at least one antenna element is set to a range between 40% and 60%.
