摘要
本文介绍了低温技术在超导核磁共振成像装置(MRI)中的应用,主要包括磁体杜瓦的真空绝热技术、闭环制冷系统及维护MRI正常运行低温液体的供给及添加技术,提出了超导MRI中低温技术的研究方向。
The application of cryogenic technigucs in Superconducting Nuclear Magnet Resonance Image Equipment (MRI) was introduced. It mainly included vacuum heat insulation of magnet dewar, closed cycle refrigerating system and the filling of cryogenic liquid to maintain the MRI working normally. A guidance for cryogenic study in MRI was given out briefly.
