Title (EN) MAGNETIC RESONANCE IMAGING APPARATUS
(FR) APPAREIL D'IMAGERIE PAR RÉSONANCE MAGNÉTIQUE
(JA) 磁気共鳴イメージング装置
Abstract:
(EN) An MRI apparatus (10) includes: a superconducting coil (115) that includes a high-temperature superconducting material and that generates a static magnetic field to which a subject (170) is exposed; and a DC power supply device (200) that supplies a direct current to the superconducting coil (115). The DC power supply device (200) is configured to allow setting of a plurality of magnetic-field intensities by adjusting the amplitude of the output current that is supplied to the superconducting coil (115).
(FR) La présente invention concerne un appareil d'IRM (10) qui comprend : une bobine supraconductrice (115) qui comprend un matériau supraconducteur à haute température et qui génère un champ magnétique statique auquel est exposé un sujet (170); et un dispositif (200) d'alimentation électrique en courant continu qui fournit un courant continu à la bobine supraconductrice (115). Ledit dispositif (200) d'alimentation électrique en courant continu est conçu pour permettre de régler une pluralité d'intensités de champ magnétique en ajustant l'amplitude du courant de sortie qui est fourni à la bobine supraconductrice (115).
(JA) MRI装置(10)は、高温超電導材料を含み被検体(170)が曝露する静磁場を発生するための超電導コイル(115)と、超電導コイル(115)に直流電流を供給する直流電源装置(200)とを備える。直流電源装置(200)は、超電導コイル(115)へ供給する出力電流の大きさを調整することによって、複数の磁場強度を設定することが可能に構成される。
