High-Performance High-Field Parallel MRI.

描述（由申请人提供）：在这个持续的项目中，我们的团队旨在开发和部署新型远程环绕多元素发射器和探测器阵列结构，用于高性能高场磁共振成像。尽管传统观点认为紧密贴合的身体轮廓线圈，但我们计划构建的新结构将消除紧密贴合的多元件阵列的许多实际和基本缺点，同时保留所有自由度，并通过包含在高磁场强度下具有独特优势的新型RF场元件来增强成像性能。在为3特斯拉和7特斯拉的操作构建了几个原型之后，我们将展示这种新的“非接触式”图像采集技术的潜在好处，无论是单独使用还是与靶向局部线圈结合使用，都可以可视化疾病过程，如胰腺癌和髋关节骨关节炎，这已经被证明是传统MRI方法的挑战。这项持续的工作是在R01项目的第一个资助期成功之后进行的，该项目为快速MRI领域引入了广泛的技术和方法创新。

DESCRIPTION (provided by applicant): In this continuing project, our team aims to develop and deploy novel remote encircling many-element transmitter and detector array structures for high-performance high-field magnetic resonance imaging. Whereas conventional wisdom argues for close-fitting body-contoured coils, the new structures we plan to build will eliminate the many practical and fundamental disadvantages of close-fitting many-element arrays, while preserving all degrees of freedom, and enhancing imaging performance through the inclusion of novel RF field elements of unique benefit at high magnetic field strength. After constructing several prototypes for 3 Tesla and 7 Tesla operation, we will demonstrate potential benefits of this new "contact-free" image acquisition technology, whether alone or in combination with targeted local coils, for visualization of disease processes such as pancreatic cancer and hip osteoarthritis, which have proven to be a challenge for traditional MRI approaches. This continuing work follows the successful first funding period of an R01 project which introduced a wide range of technological and methodological innovations to the field of rapid MRI.
