DESCRIPTION (provided by applicant): The cost of installing and maintaining current superconducting MRI systems has limited their widespread distribution in the developing world and rural areas of the US. The availability of low-cost high image quality MRI systems would improve access to clinically advanced MR applications, and would improve diagnosis and care of patients. High image quality greatly improves the capability of MRI systems in advanced medical applications such as cardiac and neurological scanning. The objective of this program is to develop technologies that enable easily sitable, low-cost whole-body MRI systems with high image quality, which will greatly expand the MRI in- stall base to include underserved areas and underdeveloped regions. With the successful development of the proposed magnet technologies, MRI systems can be realized with cost and suitability requirements comparable to today's low-cost permanent magnet systems (magnetic field of 0.2 - 0.35 T), but with a high magnetic field (1.5 - 3.0T) and excellent image quality comparable to existing mainstream and premium superconducting systems. This program will: 1. Develop new cryogen-free low-cost magnet technologies. 2. Demonstrate technologies, such as a cryogen-free cooling system and a MgB2 magnet, that can enable easily sitable low-cost MRI systems. PUBLIC HEALTH RELEVANCE: The long-term objective of this program is to develop easily siteable MgB2, low-cost whole-body MRI systems with high image quality, which will greatly expand the MRI installed base to include underserved areas and underdeveloped regions. With the successful development of the proposed magnet technologies, MRI systems can be realized with cost and sitability requirements comparable to today's low-cost permanent magnet systems (magnetic field of 0.2 - 0.35T), but with a high magnetic field (1.5 - 3.0T) and excellent image quality comparable to existing mainstream and premium superconducting systems.

描述（由申请人提供）：安装和维护当前超导MRI系统的成本限制了其在发展中国家和美国农村地区的广泛分布。低成本高图像质量MRI系统的可用性将改善对临床先进MR应用的访问，并将改善患者的诊断和护理。高图像质量大大提高了MRI系统在心脏和神经扫描等高级医疗应用中的能力。该计划的目标是开发技术，使易于安装，低成本的全身MRI系统具有高图像质量，这将大大扩大MRI的安装基地，包括服务不足的地区和欠发达地区。随着拟议磁体技术的成功开发，MRI系统的成本和适用性要求可与当今的低成本永磁系统（磁场为0.2 - 0.35 T）相媲美，但具有高磁场（1.5 - 3.0 T）和与现有主流和优质超导系统相媲美的出色图像质量。该计划将：1。开发新的无冷冻剂低成本磁体技术。2.展示无冷冻剂冷却系统和MgB 2磁体等技术，这些技术可以轻松实现低成本MRI系统。公共卫生相关性：该计划的长期目标是开发易于安装的MgB 2，低成本的全身MRI系统，具有高图像质量，这将大大扩大MRI安装基础，包括服务不足的地区和欠发达地区。随着所提出的磁体技术的成功开发，MRI系统可以实现与当今的低成本永磁系统（0.2 - 0.35T的磁场）相当的成本和可坐性要求，但具有与现有的主流和优质超导系统相当的高磁场（1.5 - 3.0T）和优异的图像质量。
