Affordable Cryogen-Free Point-of-Care 1.5 T Extremity MRI

描述（由申请人提供）：这个快速通道项目的总体目标是将超导磁体设计的创新与固态MRI的新发展结合起来，创造一种高度紧凑、坚固、可移动、轻便且价格合理的MRI，用于扫描大多数公众的周边骨骼，包括膝盖。这种扫描仪将使用一种独特的无低温3孔主动屏蔽超导磁体，使扫描仪成为现实的“护理点”设备，可以安装在较小的诊所，甚至医生的办公室。该扫描仪采用了一种创新的磁铁设计，允许患者将双腿舒适地伸展到两个独立的温暖的磁铁孔中。设计和制造高场（1.5T及以上）无低温MRI磁体的成熟技术与创新的3孔扫描仪相结合，将为老年公众提供多功能，现实的1.5T膝可及性肢体MRI提供重大突破。

DESCRIPTION (provided by applicant): The overall goal of this Fast Track project is to combine innovations in superconducting magnet design and new developments in solid state MRI to create a highly compact, robust, mobile, lightweight, and affordable MRI for scanning the peripheral skeleton, including the knee, of the majority of the public. This scanner will use a unique, cryogen-free 3-bore actively shielded superconducting magnet that makes the scanner a realistic "point-of- care" device that can be installed in smaller clinics, or even a doctor's ofice. The proposed scanner uses an innovative magnet design that allows the patient to have both legs comfortably stretched out into two separate warm bores of magnet. The combination of proven technologies in design and manufacturing of high-field (1.5T and higher) cryogen-free MRI magnets and the innovative 3-bore scanner will provide a significant breakthrough in providing a versatile, realistic point-of-care 1.5 T knee-accessible extremity MRI to the aging public.
