Fielded-cycled MRI uses resistive magnets instead of superconducting magnets to produce tissue magnetization. Due to the T1 dispersion curve, modification of the magnetic waveforms will produce different amounts of magnetization. This design study discuses the benefits of various pulse sequences from the point of view of power-supply choice. It was found that that simple constant-voltage supplies produce magnetization equivalent to more complicated power-supplies for a given amount of magnet heating.
