Abstract
A magnet for magnetic resonance imaging of the type arranged to provide fields suitable for imaging in an imaging region outside of the physical structure of the magnet, such as a magnet including plural concentric superconducting coils, generates a field having near-zero radial curvature at one location. Shim coils are actuated to adjust this location in synchronism with tuning of the RF transceiver for slice selection, so that when each slice is selected, that slice is coincident with the location of near-zero radial curvature.
