7-Tesla Ultrahigh Field Magnetic Resonance Imaging System

欧文湖哈恩磁共振成像研究所自2006年以来运营着一个7特斯拉的超高场磁共振成像系统供人类使用。来自杜伊斯堡-埃森和奈梅亨两所大学不同院系的八名主要研究人员及其研究小组在神经科学和放射诊断的各个领域进行7特斯拉研究，直到身体成像应用。开发和应用范围从基础研究到序列和方法开发，再到硬件开发，最后到超高场磁共振成像新的临床和诊断应用的评估。在2006年安装时，7特斯拉磁共振系统在欧文L。哈恩研究所是全球第六个安装，欧洲第二个安装。在方法和硬件开发以及人类超高场磁共振成像的首次诊断应用方面的许多开创性项目和出版物都来自Erwin L.哈恩研究所。由于与临床研究合作伙伴的独特合作关系，约5500名志愿者和患者已被纳入众多研究，并在13年的运营中成功进行了检查。 在这项提案中，一个新的7特斯拉最新一代的超高场磁共振系统被申请，以完全取代今天13岁的超高频磁共振成像系统在欧文L。哈恩研究所，并更新该研究所的技术中心。新的7特斯拉系统包括一个减少氦气消耗的主动屏蔽磁体，一个强大而快速的梯度系统（80 mT/m，200 mT/m/ms），8通道并行射频发射系统技术，64通道射频接收系统和快速主机和图像重建计算机。此外，安装了最新的操作系统，允许7 T超高场系统与在1.5和3.0 T下运行的临床磁共振成像系统之间的序列和方法的兼容性和可互换性。因此，新的7特斯拉超高场磁共振系统是Erwin L.的所有八个研究小组成功继续和扩展研究活动的必要先决条件。哈恩研究所。

The Erwin L. Hahn Institute for MR Imaging since 2006 operates a 7-Tesla ultrahigh-field magnetic resonance imaging system for human use. Altogether eight principal investigators and their research groups from different faculties of the two founding Universities of Duisburg-Essen and Nijmegen pursue 7-Tesla research in various areas of neuro sciences and in radiological diagnostics up to body imaging applications. The development and application spectrum ranges from fundamental research to sequence and methods development, to hardware development and finally to the evaluation of new clinical and diagnostic applications of ultrahigh-field magnetic resonance imaging. At installation in 2006, the 7-Tesla magnetic resonance system at the Erwin L. Hahn Institute was the 6th installation worldwide and second in Europe. Numerous pioneering projects and publications in methods and hardware development and first diagnostic applications of human ultrahigh-field magnetic resonance imaging result from this early phase of ultrahigh-field magnetic resonance imaging research at the Erwin L. Hahn Institute. Due to the unique partnership with clinical research partners, about 5500 volunteers and patients have been included into numerous studies and successfully examined in the 13 years of operation. In this proposal, a new 7-Tesla ultrahigh-field magnetic resonance system of the newest generation is applied for to fully replace the today 13-year old UHF MRI system at the Erwin L. Hahn Institute and to update the technical centrepiece of the institute. The new 7-Tesla system comprises an actively shielded magnet with reduced helium consumption, a strong and fast gradient system (80 mT/m, 200 mT/m/ms), 8-channel parallel radiofrequency transmit system technology, a 64-channel radiofrequency receive system and fast host and image reconstruction computers. Furthermore, the most current operating system is installed allowing for compatibility and interchangeability of sequences and methods between the 7-Tesla ultrahigh-field system and the clinical magnetic resonance imaging systems operating at 1.5 and 3.0 Tesla. The new 7-Tesla ultrahigh-field magnetic resonance system is, therefore, an essential precondition for the successful continuation and extension of the research activities of all eight research groups at the Erwin L. Hahn Institute.
