Abstract

A nuclear magnetic resonance coil configuration having at least one flat or cylindrical coil (18), through which current flows in operation, which coil generates a high-frequency magnetic B1 field at the location of a sample (16) which is oriented parallel to an x-axis, and which for the purpose of connection to a tuning network is connected to at least two electrical feed lines (11), through which in-phase currents flow in operation, and which generate a high-frequency magnetic B2 field in the sample (16), the orientation of which encloses an angle α with the direction of the B1 field, is characterized in that the following applies for the angle α: α=180°±Δα, where Δα<90°. In this way, a B1 field profile, which is as rectangular as possible and is particularly steep on both sides, can be generated.

Dependent claims

A nuclear magnetic resonance coil configuration for examination of a sample, the coil configuration comprising:

at least one flat or cylindrical coil through which a current flows in operation, said current flow in said coil generating a B1 high-frequency magnetic field at a location of the sample, wherein said B1 high-frequency magnetic field is oriented parallel to an x-axis;
and
at least two electrical feed lines, said electrical feed lines being disposed, structured and dimensioned to connect said coil to a tuning network, wherein at least a fraction of said current generating said B1 high-frequency magnetic field also flows through said electrical feed lines in operation, said current flow in said electrical feed lines thereby generating a B2 high-frequency magnetic field in the sample having a same phase as said B1 high-frequency magnetic field, said B2 high-frequency magnetic field being oriented at an angle α with respect to a direction of said B1 high-frequency magnetic field, wherein α=180°±Δα, with Δα<90°.
