In this abstract, discussion of a new method to obtain the frequency response and input impedance of MRI coils using 3D computational electromagnetics methods is provided. Studies of a TEM resonator empty and loaded (with a spherical phantom as well as an anatomically detailed human head) are provided, in addition to experimental verification of the results obtained using the new simulation technique. Comparison of the frequency response of all 16 drive ports of a head-loaded TEM coil is provided showing the variations in the coils input impedances.
