Abstract
Apparatus for generating a magnetic high-frequency field and/or for receiving corresponding high-frequency signals in a nuclear spin resonance apparatus, especially in medical technology, contains a surface coil which can be arranged within an at least partially homogeneous magnetic field region of a magnetic field which is generated by a base field magnet and is oriented along an axis, in the vicinity of a body or body part to be examined. In this apparatus, the sensitivity of the surface coil in the depth direction should be increased and be adjustable. In order to accomplish this adjustment, the surface coil has several turns which enclose each other at least partially and which are arranged at different geometrical points. Each turn preferably comprises substantially a single conductor section or of several conductor sections arranged in a group, the current flow directions being opposed to each other in mutually adjacent turns.
