SUPERCONDUCTING OPEN MRI MAGNET WITH TRANSVERSE MAGNETIC FIELD

摘要

The present invention relates to magnets and to magnetic resonance imaging systems. The magnet is open with magnetic coils arranged in quadrant, separated about two perpendicular planes, a midplane and a plane of reflection, and wherein the windings are configured such that, in operation, current flow is symmetrical about the plane of refection and anti-symmetrical about the midplane, to produce a nett magnetic field at the centre in a direction perpendicular to the plane of reflection.
