2133462 9321645 PCTABS00027 Superconducting electromagnets suitable for use in the NMR tomography of human organs, and a method of making the same, are disclosed. Each of the disclosed electromagnets are constructed according to a structured coils methodology. The magnet construction results in a plurality of coils of varying current polarity, and of irregular shape and size (106, 108, 110, 112, 114), optimized to provide the uniform field. Magnets may be constructed according to the present invention which provide suitably highly uniform and high magnitude DC magnetic fields at volumes of interest which may be within or outside of the magnet bore, enabling the MRI of human organs without requiring whole body insertion of the patient into the magnet bore. |
