摘要
该文对核磁共振成象设备的氦气放空管道的结构、技术要求、氦气回收系统工作原理、主要技术指标、使用情况等做了介绍. 91年为成都华西医科大学附一院设计制作的氦气放空管道和氨气回收系统,在正式使用前由Elscint S·Rotem低温磁体专家做了认真了解和全面检查,给予了较高评价.在第一次用液氦予冷磁体和输液过程中,总共回收氦气284.5M^3,回收率为94.3％。
One Superconducting MRI device was installed in West China Medical Science University in 1992.Its helium gas vrnt pipe and receiving system are described.Structure; specification aad application of the helium gas vent pipe and receiving system are presented.It's successful in designing and making the vend pipe and receiving system.During the period of precooling and filling helium 284.5M3 of helium gas is received.The received ration of helium gas is 94.3%
