Abstract: Apparatus for magnetic resonance imaging which includes a magnet (2) having a yoke (8) which is smoothly curved to prevent flux loss, as well as to reduce the size of the magnet whilst retaining the useful volume. The apparatus also includes providing a single enclosure (30) for the imaging device and shielded vehicles (50, 70) for enclosing patients during imaging.

Abstract: An electromagnet comprising a ferromagnetic yoke which comprises a yoke. Mutually opposing first and second pole pieces are provided. The first pole piece is provided with a planar coil having a first side facing the yoke and a second side facing the yoke. A balancing member is arranged on the second side of the planar coil to counterbalance the attractive force between the planar coil and the yoke. The other pole piece may also be provided with a corresponding balancing member.

Abstract: A hybrid magnet for an MRI machine, the magnet comprises a superconducting coil and a pole piece assembly associated with therewith. The pole piece assembly comprises a ferromagnetic member having a primary face for facing a subject to be imaged. A shim unit is separated from the primary face of the ferromagnetic member. A plurality of field-shaping permanent magnets is situated between the shim unit and the primary face of the ferromagnetic member.

Abstract: An electromagnet assembly comprises a first pair of substantially co-planar coils wound in opposite senses to each other. It further comprises a second pair of co-planar coils also wound in opposite senses to each other. The coil pairs are arranged substantially parallel to, and spaced apart from, each other. In use, the field shape and direction produced by the first coil pair are substantially mirrored by those produced by the second coil pair.
