Ideal current patterns maximize the SNR for a position
within the imaging sample. Our work demonstrates that in
imaging a central voxel, addition of a dielectric layer
surrounding a spherical sample results primarily in a
phase lag in the ideal current patterns corresponding to
the additional propagation time through the layer. For
an off-center voxel, the ideal current pattern covers a
larger area when the dielectric layer is present,
indicating that larger sized coils are optimal in this
case. Our results provide an understanding of
electromagnetic field behavior with dielectric
materials, and provide a method to predict optimal coil
design.
