A technique is described for localization of MR signals from a target volume using nonlinear pulsed magnetic fields and spatial encoding trajectories designed using local k-space theory. In vivo human brain images were obtained using a custom quadrupolar gradient coil integrated with a whole-body 3 T MRI scanner to demonstrate localization in 3D T2*-weighted imaging.
