Open architecture magnetic resonance imaging superconducting magnet assembly |
| 摘要 |
<p>A passively shimmed open architecture magnetic resonance imaging magnet (10) utilizing separated superconducting coil assemblies (12,13) with open space (11) between including means to obtain a uniform magnetic field in the open space by shaped ferromagnetic bands (58) in the bore (4) of the magnets, the shaping including an axial notch and circumferential holes (33,35,37) for attaching passive shims (39). <IMAGE></p> |
