Optimization of Conductor Geometries of Small RF Loop Coils for Ultra High Field Applications

David Otto Brunner¹, Clemens Grassberger¹, Klaas Paul Pruessmann¹

Small receiver loop coils offer high SNR gain and are therefore common practice in MRI and MRS. In this work it was tried to optimize the conductor geometry and size of such loop coils comparing a series of conical coils with varying shell angles, diameters and placements. Furthermore the dependence of these parameters on the dielectric properties of the sample has been studied, which turned out to have a major impact at these frequencies.
