ABSTRACT:
An apparatus for generating a magnetic high-frequency field and/or for receiving corresponding high-frequency signals in nuclear spin resonance apparatus, particularly in medical technology, comprises a coil winding 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, at least in the vicinity of a body or body parts to be examined. This apparatus improves the ability to localize the atomic nuclei emitting the resonance signals. For this purpose, a high-frequency coil winding of substantially rectangular shape is provided, wherein at least two parallel longitudinal conductor sections of the winding are made substantially longer than the transverse conductor sections which connect them to each other and extend transversely. The longitudinal conductor sections are arranged at least largely perpendicularly to the orientation direction of the magnetic field of the base field magnet, and the transverse conductor sections are preferably spaced at a greater distance from the body to be examined than the longitudinal conductor sections.
