Magnetic field generating device for NMR-CT. |
摘要 |
<p>A magnetic field generating device for nuclear magnetic resonance-computerized tomography comprising a pair of permanent magnets magnetized in the same direction with different-polarity poles mutually opposed to define an air gap, whose maximum energy product, (BH)max, is not less than 240 kJ/m<3>, each of the opposing faces of the permanent magnets having a magnetic pole facing provided with an annular rib and, as occasion demands, at least one inner projection inside the annular rib, and the permanent magnets being coupled magnetically by a yoke to generate a magnetic field within the air gap. The prsent device is able to create a uniform and stable magnetic field, in spite of its small-sized body.</p> |
