Project Summary This proposal is aimed at converting a head-only 7T Agilent/Varian MRS scanner to a 7T Siemens scanner by replacing the console and all the RF, and gradient hardware. This will yield a state-of-the-art MRS and MRI system to serve the research needs of up to 60 principal investigators that currently scan in the Yale Magnetic Resonance Research Center (MRRC). The upgrade solves several problems. First Agilent has announced it is no longer going to make 7T magnets so if Yale is to have a 7T MRI, upgrading this existing system is the only path forward. Second because of this announcement from Agilent, support for the current system will shortly no longer be available and this expensive/important resource may be lost without such an upgrade. Third we have a strong demand at Yale for both structural and functional imaging capabilities at very high spatial and temporal resolution and by upgrading this magnet we can provide such capabilities to a large research community both within and outside of Yale. Furthermore we have several training programs in both engineering and neuroscience that would benefit from access to this upgraded high field imager. We have the technical expertise, the research relationship with Siemens, several exceptionally strong research programs, and the user needs, to justify this investment. Yale has invested a considerable amount of resources in the MRRC and in this case would provide 50% of the cost of this upgrade demonstrating the importance the university puts on this resource. This would be the only head-MRI 68cm bore 7T Siemens system in the USA. Two others exist in the world - one in Luasanne, Switzerland and the other in Waterloo, Canada and thus this would be a unique resource.

项目概要 该提案旨在将头部 7T 安捷伦/瓦里安 MRS 扫描仪转换为 7T 西门子扫描仪 更换控制台以及所有 RF 和梯度硬件。这将产生最先进的 MRS 和 MRI 系统可满足目前在耶鲁大学磁学扫描的多达 60 名主要研究人员的研究需求 共振研究中心（MRRC）。此次升级解决了几个问题。首先安捷伦宣布它是 不再生产 7T 磁铁，因此如果耶鲁大学要拥有 7T MRI，升级现有系统是唯一的选择 前进的道路。其次，由于安捷伦的这一声明，对当前系统的支持很快就会实现 不再可用，如果不进行此类升级，这种昂贵/重要的资源可能会丢失。第三我们 耶鲁大学对非常高的空间和功能成像能力有强烈的需求 时间分辨率，通过升级这种磁铁，我们可以为大型研究提供这样的能力 耶鲁大学内外的社区。此外，我们在这两个领域都有多个培训项目 工程和神经科学将受益于这种升级的高场成像仪。我们有 技术专长、与西门子的研究关系、几个异常强大的研究项目、 和用户需求，以证明这项投资的合理性。耶鲁大学投入了大量资源 MRRC 在本例中将提供本次升级成本的 50%，这表明了升级的重要性 大学提供了这个资源。这将是美国唯一的头部 MRI 68 厘米孔径 7T 西门子系统。 世界上还存在另外两个 - 一个在瑞士卢桑，另一个在加拿大滑铁卢，因此这个 将是一种独特的资源。
