FIGURE 8.

A comparison between the transfer functions obtained with finite‐difference time‐domain simulations and the transfer function obtained with MRI. The top row shows the magnitude and phase of the transfer function for the bare copper wire; the second row shows the same for the insulated copper wire; the third row shows the TF for the coaxial lead; and the bottom row is the TF for the spinal cord stimulator. For all of the TFs, the blue‐shaded area displays the SD of the measured TF
