While most work with high permittivity materials (HPMs)
in MRI has been focused on improving SNR or transmit
efficiency for a relatively small region within a much
larger coil or array, more recent work demonstrates that
HPMs can also improve performance of smaller coils very
near the subject, as well as arrays of such coils for
the entire region of the anatomy they encompass. Here we
illustrate differences in the nature of coil
functionality when HPMs are present with graphical plots
and analysis of both conduction currents and
displacement currents.
