Low Cost Open MRI Systems using MgB2 Coils

描述（由申请人提供）：我们正在开发一种低成本的超导导线，与仅在4 K下工作的MRI用传统金属超导体相比，该超导导线可以在4-30 K范围内工作。这将实现更低成本的MRI和更低的每位患者进行MRI分析的成本。MRI系统成本是为患者进行MRI（尤其是开放式MRI）的每例患者成本中最大的成本驱动因素。通过降低MRI系统的成本，患者的成本将降低。如果超导工作温度可以从4K提高到20 K，则降低MRI系统的成本可以是显著的。该提议的第二阶段的目标是证明MgB 2超导体线可以在开放和封闭MRI系统的10-30 K范围内运行的线圈中制造。在SBIR第1阶段，Hyper Tech Research展示了小型线圈，其磁场足够高，可用于开放式和封闭式MRI系统。在本阶段II中，我们打算证明更长长度和线圈形式的导线性能得到改善，因此可以开发更大的开放式MRI系统。我们打算证明持久的关节，并通过合作MRI制造商在几个MRI公司开始MgB 2线圈的开发工作

DESCRIPTION (provided by applicant): We are developing a low cost superconductor wire that can operate in the 4-30 K range compared to traditional metal superconductors for MRIs that operate at only 4 K. This will enable a lower cost MRI and a lower per patient cost to do a MRI analysis. The MRI system cost is the largest cost driver in the per-patient cost to do a MRI for a patient especially with open MRIs. By lowering the cost of MRI systems the cost to patients will be lower. Lowering the cost of the MRI system can be significant if the superconducting operating temperature can be raised from 4 K to 20 K. The goal of this proposed Phase II is to demonstrate that MgB2 superconductor wires can be fabricated in coils that function in the 10-30 K range for open and enclosed MRI systems. In the SBIR Phase 1 Hyper Tech Research demonstrated small coils with fields high enough to be useful for open and enclosed MRI systems. In this Phase II we intend to demonstrate improved wire properties in longer length and in coil form so larger open MRI systems can be developed. We intend to demonstrate persistent joints and through collaborating MRI manufacturers initiate MgB2 coil development efforts at several MRI companies
