MRI using radiofrequency magnetic field phase gradients
Magnetic Resonance in Medicine, 2009 AbstractConventionally, MR images are formed by applying gradients to the main static magnetic field (B0). However, the B0 gradient equipment is expensive, power‐hungry, complex, and noisy and can induce eddy currents in nearby conducting structures, including the patient.

Rigorous evaluation of the edge-focusing wiggler based on the magnetic field measurement
Physical Review Special Topics. Accelerators and Beams, 2009 The edge-focusing (EF) wiggler, which produces the strong field gradient for transverse focusing incorporated with the normal wiggler field, has been fabricated to evaluate its performance rigorously with the magnetic field measurement.
