 DESCRIPTION (provided by applicant): This NIH Bridge Grant will result in a conduction cooled, liquid helium free, MRI background magnet for a commercial image guided radiation treatment (IGRT) for cancer treatment. The program will ensure the successful continued commercialization of our customer's image guided radiation therapy (IGRT) system, a vital cancer treatment device now treating patients. The result of the project removes our customer's present system from its dependence on liquid helium, the availability of which is threatened by worldwide shortages in the next few years. The cancer treatment system makes available image guided radiation therapy (IGRT) that delivers gamma radiation in real time to malignant tumors with pinpoint accuracy in spite of organ movement. This is realized with the concurrent real time radiation treatment and MRI imaging. The results of this Bridge Grant through Hyper Tech makes possible the uninterrupted progress of this vital technology by providing a helium-free cryocooled background magnet based on our magnesium diboride (MgB2) superconducting wire. These MgB2 magnet systems will not only significantly lower the initial cost but will reduce on-going service costs of our customer's image guided radiation therapy system. In addition, the magnet system will be safer and less prone to quenching. These magnets will replace the current liquid helium bath dependent niobium titanium (NbTi) superconductor background magnets in the MRI system. During the project we will complete and finalize the modelling and design, complete detail drawings, fabricate the magnet components and the superconductor wire. We will wind and test the individual coils in the system. We will fabricate, assemble, and test the magnet system and deliver it to our customer for integration and testing into their image guided radiation therapy system.

 描述(由申请者提供)：这项美国国立卫生研究院的桥梁拨款将导致一种用于癌症治疗的商业图像引导放射治疗(IGRT)的传导冷却、无液氦、MRI背景磁体。该计划将确保我们客户的图像引导放射治疗(IGRT)系统成功地继续商业化，这是一种重要的癌症治疗设备，目前正在治疗患者。该项目的结果使我们客户目前的系统摆脱了对液氦的依赖，液氦的供应在未来几年受到全球短缺的威胁。癌症治疗系统提供了图像引导放射治疗(IGRT)，它可以在器官移动的情况下，以精确的精度向恶性肿瘤实时提供伽马辐射。这是通过实时放射治疗和MRI成像并行实现的。通过Hyper Tech的桥梁赠款的结果使这项重要技术的不间断进步成为可能，因为它提供了一种基于我们的二硼化镁(MgB2)超导导线的无氦低温冷却背景磁体。这些镁B2磁体系统不仅将显著降低初始成本，还将降低我们客户的图像引导放射治疗系统的持续服务成本。此外，磁体系统将更安全，更不容易淬火。这些磁体将在磁共振成像系统中取代目前的液氦浴相关的NbTi(NbTi)超导背景磁体。在项目期间，我们将完成并最终完成建模和设计，完成详细图纸，制造磁铁部件和超导导线。我们将对系统中的单个线圈进行缠绕和测试。我们将制造、组装和测试磁铁系统，并将其交付给我们的客户，以便集成和测试到他们的图像引导放射治疗系统中。
