1. A radio-frequency coil arrangement comprising:
- a plurality of conductor traces forming a plurality of basic radio-frequency coils with capacitors interconnected in said conductor traces, respective conductor traces of respective different ones of said basic coils intersecting at node points, and each basic radio-frequency coil exhibiting a basic coil configuration; and
at least some of said node points being switchable node points comprising at least one switching arrangement operable to selectively, reversibly connect or disconnect the conductor traces at that switchable node point to cause the respective basic radio-frequency coils having said conductor traces at said switchable mode to point to deviate from said basic configuration to allow selective, reversible formation of a plurality of different coil geometries.

Abstract
A radio-frequency coil arrangement has a number of conductor traces forming basic coils and with capacitors interconnected in the conductor traces. Conductor traces of various basic coils intersect at node points. At least one switching arrangement for selective, reversible connection of the conductor traces to form different coil geometries is provided at least some of the node points.

17. A magnetic resonance apparatus comprising:
-
a magnetic resonance data acquisition unit configured to interact with a subject to acquire magnetic resonance data therefrom; and a radio-frequency coil arrangement that participates in the acquisition of said magnetic resonance data, said radio-frequency coil arrangement comprising a plurality of conductor traces forming a plurality of basic radio-frequency coils with capacitors interconnected in said conductor traces, respective conductor traces of respective different ones of said basic coils intersecting at node points, and each basic radio-frequency coil exhibiting a basic coil configuration, and at least some of said node points being switchable node points comprising at least one switching arrangement operable to selectively, reversibly connect or disconnect the conductor traces at that switchable node point to cause the respective basic radio-frequency coils having said conductor traces at said switchable mode to point to deviate from said basic configuration to allow selective, reversible formation of a plurality of different coil geometries.
