DESCRIPTION (provided by applicant): The expense involved in installing and providing cryogen service to current superconducting MRI systems has limited their widespread distribution, especially in less populous regions of the country, as well as in underdeveloped countries. The MRI scanners found in these areas are most often of the low field (0.2-0.35T) type using Permanent Magnet (PM) technology. These systems have a lower image quality and are not cost-effective when compared with superconducting systems. The objective of this program is to develop enabling technologies for a low-cost, easily siteable superconducting MRI system with a magnetic field strength and image quality comparable to existing solenoidal superconducting systems of 1.0 - 1.5 T magnetic field strength. The system will be easily siteable in underdeveloped areas since it will not require liquid cryogens and will be designed to survive power outages with minimal operator intervention. The program will: 1) Develop key magnet technologies for cryogen-free operation and power-outage survivability. 2) Develop key technologies for PITS wire including a joining method. 3) Prove the developed technologies by building an orthopedic imaging system. 4) Evaluate the performance of the orthopedic imaging system in terms of image quality and system reliability.

描述（由申请人提供）： 为当前的超导 MRI 系统安装和提供冷冻剂服务所涉及的费用限制了其广泛分布，特别是在该国人口较少的地区以及不发达国家。这些区域中的 MRI 扫描仪通常是使用永磁 (PM) 技术的低场 (0.2-0.35T) 类型。与超导系统相比，这些系统的图像质量较低，并且不具有成本效益。该项目的目标是开发低成本、易于定位的超导 MRI 系统的支持技术，其磁场强度和图像质量可与现有 1.0 - 1.5 T 磁场强度的螺线管超导系统相媲美。该系统将很容易安装在欠发达地区，因为它不需要液态制冷剂，并且可以在停电时以最少的操作员干预来生存。该计划将： 1）开发无制冷剂运行和断电生存能力的关键磁体技术。 2）开发PITS线材连接方法等关键技术。 3）通过构建骨科成像系统来验证所开发的技术。 4) 从图像质量和系统可靠性方面评估骨科成像系统的性能。
