| 摘要 |
The purpose of the present invention is to provide a magnetic field-generating device that has a small and simple configuration and high magnetic field homogeneity, a magnetic resonance imaging apparatus using same, and a magnetization unit for high temperature superconducting bulks. The present invention is provided with: a thermally insulated vacuum container (14); a high temperature superconducting bulk (11), which is disposed inside the thermally insulated vacuum container (14), through which a superconducting current flows and which traps a magnetic field by being cooled and said magnetic field being applied, and which supplies the supplemented magnetic field; and a refrigerator (13) for cooling the high temperature superconducting bulk (11) to a very low temperature. The high temperature superconducting bulk (11) is magnetized using a magnetization unit (30) for applying a magnetic field on the high temperature superconducting bulk (11), and a detachable magnetic field-adjusting unit (20) for adjusting the magnetic field near the high temperature superconducting bulk (11). |
