NMR radio frequency coil with dielectric loading for improved field homogeneity |
摘要 |
An RF coil assembly for an NMR instrument includes a cylindrical coil surrounded by a cylindrical shield. The annular space between the coil and the shield is filled with a dielectric material having a relative permittivity selected to improve the RF field homogeneity in the radial direction.
