Claude Prevot: Gradient coil for image formation devices using nuclear magnetic resonance. Thomson CGR, Oblon Fisher Spivak McClelland & Maier, April 26, 1988: US04740772 (7 worldwide citation)

The object of the invention is an improved gradient coil. The improvement consists in making steps in the saddle-shaped conductors that form the coil in order to modify local distortions in the magnetic field produced. It is shown that the correction thus made has little effect on the rest of the fi ...
