Magnetic Resonance Imaging Facilities Upgrade

德克萨斯A&amp；M公司目前在工程成像实验室拥有一台通用电气2特尔萨、31厘米直径的核磁共振系统。仪器的计算机控制是通过Nicolet 1280处理器实现的。PI指出，处理器是一个很好的系统，但不是最优的系统，它需要大量的工作来配置和执行特殊测试。PI建议购买通用电气的Omega系统，该系统包括Sun处理器以及相关的电子产品和软件，以实现更高效的仪器控制、数据采集和数据分析。升级后的仪器将用于几个项目，其中大部分涉及将磁共振技术应用于研究多孔介质中的流体流动。其中一些项目是：(I)使用磁共振成像来确定流体、其饱和度、润湿性以及在多孔介质中的原位速度和渗透率；(Ii)使用磁共振成像来评估孔隙结构；(Iii)使用磁共振成像来研究化学稳定的驱油剂，如泡沫和聚合物溶液的驱油作用。

Texas A&M currently possesses a General Electric 2 telsa, 31 cm bore MRI system located in the Engineering Imaging Laboratory. Computer control of the instrument is via a Nicolet 1280 processor. The PI notes that the processor is a good, but not optimal system, and that it requires significant effort for the configuration and execution of special tests. The PI proposes purchasing a General Electric Omega System which includes a Sun processor and associated electronics and software for more efficient instrument control, data acquisition and data analysis. The upgraded instrument will be used in several projects, most of which are concerned with applying MRI technology to the study of fluids flow in porous media. Some of these projects are: (i) Using MRI to identify fluids, their saturation, wetability and in situ velocity and permeability in porous media, (ii) Using MRI to evaluate pore structure, (iii) using MRI to study oil displacement by chemically stabilized displacers such as foam and by polymer solutions.
