超导MRI磁体无液氦改造探讨

摘要

该文从国内超导磁共振成像仪(MRI)使用现状出发，在液氦市场的供求危机中，申述了超导MRI磁体无液氦改造的重要意义，并根据企业的制作流程，提出了无液氦改造操作的若干实践与设想，为国内超导MRI制造与使用提供了重要的价值取向。%In this paper, from the current situation of the domestic use of superconducting MRI, on liquid helium supply and demand crisis in the market, the significance of the transformation without LHe of the superconducting MRI magnet was explained, and according to the enterprise’s production process, a number of operating without liquid helium transformation practice and ideas were raised, important value orientation for the domestic manufacture and use of superconducting MRI was provided.
