MgB2 Croygen-Free Magnet Technologies -- Enabling Affordable MRI for Developing R

描述（由申请人提供）：目前超导MRI系统的安装和维护成本限制了其在发展中国家和美国农村地区的广泛分布。低成本高图像质量核磁共振系统的可用性将改善临床先进核磁共振应用的可及性，并将改善患者的诊断和护理。高图像质量极大地提高了MRI系统在心脏和神经扫描等先进医疗应用中的能力。该项目的目标是开发技术，使易于安装、低成本、高图像质量的全身MRI系统成为可能，这将大大扩大MRI的摊位基础，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低成本永磁系统（磁场为0.2 - 0.35 T）相当的成本和适用性要求，但具有与现有主流和优质超导系统相当的高磁场（1.5 - 3.0T）和出色的图像质量。这个程序将：1。开发新的无低温低成本磁体技术。2. 演示技术，如无低温冷却系统和MgB2磁体，可以实现易于使用的低成本MRI系统。公共卫生相关：该项目的长期目标是开发易于定位的MgB2、低成本、高图像质量的全身MRI系统，这将大大扩大MRI的安装基础，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低成本永磁系统（磁场为0.2 - 0.35T）相当的成本和稳定性要求，但具有与现有主流和优质超导系统相当的高磁场（1.5 - 3.0T）和出色的图像质量。

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.
