The native wave propagation mode of a coaxial waveguide (TEM) has no cut-off frequency, which offers the opportunity of broadband operation for mulit-nuclei studies. We acquired proton (1H) and sodium (23Na) images at four different Larmor frequencies from 63 to 297MHz using the same coaxial waveguide setup for both spin excitation and signal reception.
