Abstract
An HF resonator assembly generates at least two independent alternating magnetic fields in a test volume of a magnetic resonance apparatus. The HF resonator assembly includes a first pair of flat coils that form a first HF resonator and comprise electrical conductor portions that surround a planar surface portion. The flat coils are arranged on opposing sides of the test volume, on coil support plates that are mutually parallel and in parallel with the longitudinal axis. A second pair of flat coils forms a second HF resonator on second coil support plates. The projections of the planar surface portions of the flat coils in each of the first pair of flat coils and the second pair of flat coils overlap in part, but not completely, when viewed in a direction perpendicular to the respective planar surface portions.

A high frequency (HF) resonator assembly comprising:
- a test volume extending along a longitudinal axis;
- a pair of first coil support plates arranged on opposing sides of the test volume, wherein the pair of first coil support plates are mutually parallel and in parallel with the longitudinal axis;
- a first pair of flat coils that are configured to form a first HF resonator on the pair of first coil support plates;
- a pair of second coil support plates arranged on opposing sides of the test volume, wherein the pair of second coil support plates are mutually parallel, in parallel with the longitudinal axis, and perpendicular to the pair of first coil support plates;
- and
- a second pair of flat coils that are configured to form a second HF resonator on the pair of second coil support plates,
- wherein each of the flat coils comprises respective electrical conductor portions that surround a respective planar surface portion,
- wherein each coil support plate includes a respective end face facing a respective edge surface of an adjacent one of the coil support plates,
- wherein projections of the planar surface portions of the first pair of flat coils overlap in part, but not completely, when viewed in a direction perpendicular to the planar surface portions of the first pair of flat coils, and
- wherein projections of the planar surface portions of the second pair of flat coils overlap in part, but not completely, when viewed in a direction perpendicular to the planar surface portions of the second pair of flat coils.
