Abstract :
In this study, high permittivity ceramic resonators were used to produce the Bl field in a 14.1 Tesla NMR device with a proton frequency of 600 MHz. Magnetic field distributions in the setup are analyzed using the finite-difference time-domain simulations. The NMRI images obtained by using the new setup are demonstrated.
