在过去的二十年里，磁共振成像（MRI）已经发展成为一项成熟的技术，并且是超导商业化大规模应用的领先者。这仍然是一个快速发展的领域，其特点是不断出现的配置需要创新的技术解决方案，并且趋势是增加场强 B/sub 0/ 和更先进的磁性、低温和集成系统设计。本文介绍了MRI超导电磁设计的主要技术方法和挑战、磁体参数设计空间的权衡及其对超导设计的影响。讨论了最新趋势、先进的新颖配置和不同的应用。更高场强的趋势体现在临床应用向 3 T 的持续转变，以及场强高达 9.4 T 的全身 MRI 的最新发展中。插图来自商业和正在开发的 MRI 系统。
Over the past two decades, magnetic resonance imaging (MRI) has developed into a mature technology, and is the leading commercial large-scale application of superconductivity. This is still a rapidly evolving field, characterized by constantly emerging configurations requiring innovative technical solutions, with trends toward increasing field strength B/sub 0/ and more advanced magnetic, cryogenic and integrated system design. This paper describes the main technical approaches and challenges in MRI superconducting electromagnetic design, trade-offs in the magnet parametric design space and their effect on the superconducting design. Recent trends, advanced novel configurations and different applications are discussed. The trend toward higher fields manifests itself in the ongoing shift of clinical applications to 3 T, as well as in recent developments of whole-body MRI with field strength up to 9.4 T. Illustrations are presented from commercial and developing MRI systems.
