ABSTRACT:
The conductor structures of an antenna in a nuclear magnetic resonance tomography apparatus are covered with lamellae that extend in longitudinal direction of the examination space and have large-area connections at the end sides of the antenna to a shielding that surrounds the examination space. In an alternative embodiment, the lamellae extend the azimuthal direction and are connected to a shielding (3) surrounding the examination space at the respective longitudinal edges of the conductor structure of the antenna via broad-web, planar conductors with a free cross section remaining between the conductors.
