Magnetic Resonance Imaging Facilities Upgrade

德克萨斯农工大学目前拥有一台通用电气2 telsa，31 位于工程成像中的cm孔径MRI系统 实验室仪器的计算机控制是通过 尼科莱1280处理器。PI指出，处理器是一个 好的，但不是最佳的系统，它需要大量的 配置和执行特殊测试的努力。 PI建议购买通用电气Omega系统 它包括一个Sun处理器和相关的电子设备， 用于更有效的仪器控制、数据 采集和数据分析。 升级后的仪器将用于几个项目，其中大多数 其中涉及将MRI技术应用于 多孔介质中流体流动的研究。 其中一些项目 （i）使用MRI识别液体，其饱和度， 多孔介质中的润湿性、原位速度和渗透率 （ii）使用MRI评估孔结构，（iii） 利用MRI研究化学稳定剂驱油， 置换剂如泡沫和聚合物溶液。

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.
