    摘要： An electromagnet for use in an MRI apparatus includes an annular vessel inside of which annular windings, energizable to produce a magnetic field, are contained together with cold iron components. The iron components are mechanically anchored with respect to the windings. A pair of iron rings is positioned so that one ring is provided at each end of the magnet in close proximity to the annular windings. The rings are formed so as to define a flared opening at each end of a cylindrical space within the magnet which, in use of the magnet for MRI purposes, is occupied by a patient.

    摘要： A method for assembling a cylindrical magnet assembly, which includes at least one coil mounted on a former, to a bore tube is provided. The method involves providing a cavity in the former at selected locations. At each of the selected locations, the material of the bore tube is deformed to form a radially-directed protrusion. Each protrusion is brought to bear against a periphery of each corresponding cavity.
