摘要:
A surface resonator for use in a magnetic resonance imaging apparatus having a transversal fundamental magnetic field is composed of two sub-systems, each generating a magnetic field with the magnetic fields being perpendicular relative to each other. Each sub-system contains two current loops, both of which enclose the magnetic field allocated to them in the same plane. A circularly polarizing surface resonator is thus obtained for the transversal fundamental magnetic field.
