Magnetic Field Gradient Waveform Monitor (MFGM)

Hui Han¹, Bruce J. Balcom

Numerous methods have been developed to measure MRI gradient waveforms and k-space trajectories for correcting the remaining hardware imperfections. The most widely used method to characterize eddy currents behavior is a slice selection method by Duyn. The most promising new strategy appears to be magnetic field monitoring (MFM) with RF microprobes.
