High dielectric constant (HDC) disk dipoles for 10.5 T imaging

摘要: A small coil element is developed for 10.5 T imaging by affixing an end-loaded 82mm long dipole to a high dielectric constant (HDC) flat disk. This coil element produces localized but very high B 1 fields similar to a loop of a similar diameter without suffering from diverging B 1+ and B 1-that loops experience at high field. Furthermore, these elements are inherently highly decoupled in all possible spatial configurations, making them well suited to use in large, densely packed transmit arrays.
