 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（由应用提供）：该NIH桥接赠款将导致用于癌症治疗的商业图像引导辐射治疗（IGRT）的冷却，无液氦，MRI背景磁铁。该计划将确保我们客户的图像指导放射治疗（IGRT）系统的成功持续商业化，这是一种现已治疗患者的重要癌症治疗装置。该项目的结果使我们的客户目前的系统从对液体氦气的依赖中删除，其可用性在未来几年内受到全球短缺的威胁。癌症治疗系统使图像引导放射疗法（IGRT）可实时提供γ辐射，以使其具有最精确的恶性肿瘤，尽管有器官运动。这是通过并发的实时辐射处理和MRI成像实现的。通过超技术的桥梁赠款的结果通过根据我们的二吡啶镁（MGB2）超导电线提供了无氦的冷冻背景磁铁，这使这项重要技术的不间断进展成为可能。这些MGB2磁铁系统不仅将显着降低初始成本，而且会降低客户图像引导的放射治疗系统的持续服务成本。此外，磁铁系统将更安全，易于淬火。这些磁铁将取代MRI系统中当前的液态氦浴钛钛（NBTI）超导背景磁铁。在项目期间，我们将完成并最终确定建模和设计，完整的详细图纸，制造磁铁组件和超导导线。我们将在系统中进行风和测试。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集成和测试到其图像引导的放射治疗系统中。
