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. Currently, the vast majority of magnetic resonance imaging and functional imaging studies are conducted at relatively low magnetic fields of 1.5 or 3.0 Tesla. However, theoretical considerations as well as experimental evidence have suggested that there is a fundamental dependence of image signal to noise ratios, functional imaging contrast and spatial specificity on the magnetic field strength. The general aim of this proposal is development of fMRI and MRI techniques for whole brain acquisitions at high magnetic fields (7 T & 9.4 T). In achieving this aim, fMRI/MRI studies will be conducted at the ultra-high magnetic field of 9.4 Tesla for the first time in humans.

这个子项目是许多研究子项目中的一个 由NIH/NCRR资助的中心赠款提供的资源。子项目和 研究者（PI）可能从另一个NIH来源获得了主要资金， 因此可以在其他CRISP条目中表示。所列机构为 研究中心，而研究中心不一定是研究者所在的机构。 目前，绝大多数磁共振成像和功能成像研究都是在1.5或3.0特斯拉的相对较低的磁场下进行的。然而，理论上的考虑以及实验证据表明，有一个基本的依赖性的图像信噪比，功能成像对比度和空间特异性的磁场强度。该提案的总体目标是在高磁场（7 T和9.4 T）下开发用于全脑采集的fMRI和MRI技术。为了实现这一目标，fMRI/MRI研究将首次在9.4特斯拉的超高磁场下进行。
