This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Drs. Chris Collins, Qing Yang, Vaughan, Garwood, Ugurbil, and respective staffs are collaborating to identify and characterize the limitations, and to discover and develop new solution for MRI of humans at 7T and higher. The Penn State Hershey Medical Center Lab of Drs. Collins and Yang (formerly that of Dr. Michael Smith), has pioneered the development of high fidelity, highly segmented human anatomic models for numerical simulations of SNR, SAR, B1 uniformity and other physical parameters. Through theoretical simulation and empirical validation, we are able to explore the problems and find new solutions to human imaging at unprecedented field strengths. This work is supported in part by a Minnesota sub-contract to Penn State's NIH-PAR-02-010, and by Penn State's subcontract with Vaughan's NIH-EB000895.

该子项目是利用该技术的众多研究子项目之一 资源由 NIH/NCRR 资助的中心拨款提供。子项目及 研究者 (PI) 可能已从 NIH 的另一个来源获得主要资金， 因此可以在其他 CRISP 条目中表示。列出的机构是 对于中心来说，它不一定是研究者的机构。 博士。 Chris Collins、Qing Yang、Vaughan、Garwood、Ugurbil 和各自的工作人员正在合作识别和描述其局限性，并发现和开发 7T 及更高频率下人体 MRI 的新解决方案。宾夕法尼亚州立大学赫尔希医学中心博士实验室。 Collins 和 Yang（前 Michael Smith 博士）率先开发了高保真、高度分段的人体解剖模型，用于 SNR、SAR、B1 均匀性和其他物理参数的数值模拟。 通过理论模拟和实证验证，我们能够在前所未有的场强下探索问题并找到人体成像的新解决方案。 这项工作部分得到明尼苏达州与宾夕法尼亚州立大学 NIH-PAR-02-010 的分包合同以及宾夕法尼亚州立大学与旺市 NIH-EB000895 的分包合同的支持。
