项目摘要

Space Utilization: The Functional MRI Facility (FMRIF) currently occupies approximately 4800 sq. ft of space, divided between the scanner bays, control rooms and electronics/machine rooms for 3TA, 3TB, 3TC, and 1.5T MRI scanners located within the NMR center and office space on the second floor above the NMR center in the FMRIF/SFIM suite (approximately 1400 sq ft total, including shared conference space). Staff: The FMRIF staff (currently 15 full time employees) consist of: the facility director, four staff scientists to keep the scanners running, eight MRI technologists, an information technology (IT) specialist, and an administrative lab manager. Core users: The functional MRI facility supports the research of over 30 Principal Investigators which translates to over 300 researchers overall. Over 70 research protocols are active and making use of FMRIF scanners. Each scanner has scheduled operating hours of 105 hours per week. Since the year 2000 until Sep 2011, a total of 723 publications have made use of the core facility. The total is divided among 472 for NIMH, 195 from NINDS, and 56 from the other institutes). These papers have been cited 38,461 times for a combined h-index of 102. Accomplishments: This year, the FMRIF has been extremely busy with scanner purchases. We have purchased a Siemens 7T and a Siemens Skyra 3T scanner and are hoping to complete our purchase of the GE CRADA scanner and upgrade it to a GE750. The 7T will replace our 3T-C. The Skyra 3T will replace our 1.5T in January of 2011, and the GE upgrade will be on the purchased CRADA scanner which will be owned by us. Credit goes to Sean Marrett and Vinai Roopchansingh for overseeing the ongoing construction projects for these scanners. In the past year, a new staff scientist, Souheil Inati, has joined our team. He brings with him considerable expertise in MR physics and pulse programming as well as experience with Siemens platforms. In this past year, we have created a transparent "technical scan" list, allowing appropriately qualified individuals to streamline their scanning setup and testing process by being able to perform "technical scans." This privilege required extensive edits and feedback before it was ready. With regard to IT related accomplishments for the core facility: Centralized authentication for technologist The IT infrastructure for the FMRIF's eight MRI technologists has been completely overhauled to make it easier for technologists to support different scanners on different days. Their stand alone Windows workstations have been replaced with iMacs connected to a central Xserver. Each technologist can login to any of the iMacs in any scanner room and access their desktop. Virtualization We have begun a major initiative to virtualize many of the core computing hardware of the FMRIF. Virtualization has many benefits including reduced space and power consumption and increase up time and reliability. The FMRIF webserver has already been converted to a virtual machine and we expect the authentication, backup, and dicom catcher to be be converted in the coming year. Utilization Statistics We have contined to expand the accounting features of our scan scheduling database. This now enables us to produce fine-grained reports on how and when each investigator is using the scanner. For example, this year we have added the ability to compute how much notice investigators provide when giving up unneeded scantime to the community. These reports help both us and the scientific director allocate scantime to maximize the efficient utilization of FMRIF resources. Lastly over the past year, the functional MRI facility has continued the summer fMRI/MRI summer seminar series. This informal fMRI/MRI summer course is presented mostly by researchers at the NIH. While the lectures were not filmed, the digital versions of the presentations are placed on a site that allows downloading. This course has been well-received by the summer student and post bac IRTA community at the NIH. The attendance this year is about double that of last year.

空间利用率：功能性 MRI 设施 (FMRIF) 目前占地约 4800 平方英尺，分为扫描仪隔间、控制室和电子/机械室，用于 3TA、3TB、3TC 和 1.5T MRI 扫描仪，位于 NMR 中心和办公空间内位于 FMRIF/SFIM 套房 NMR 中心上方二楼（总面积约 1400 平方英尺，包括共享会议空间）。职员： FMRIF 工作人员（目前有 15 名全职员工）包括：设施主管、四名负责保持扫描仪运行的科学家、八名 MRI 技术人员、一名信息技术 (IT) 专家和一名实验室行政经理。核心用户：功能性 MRI 设施支持 30 多名首席研究员的研究，总共有 300 多名研究人员。超过 70 个研究方案正在使用 FMRIF 扫描仪。每台扫描仪的预定运行时间为每周 105 小时。自 2000 年至 2011 年 9 月，共有 723 种出版物使用了该核心设施。总数分为 NIMH 的 472 个、NINDS 的 195 个以及其他机构的 56 个。这些论文已被引用 38,461 次，综合 h 指数为 102。成就：今年，FMRIF 的扫描仪采购工作异常繁忙。我们已经购买了一台西门子 7T 和一台西门子 Skyra 3T 扫描仪，并希望完成对 GE CRADA 扫描仪的购买并将其升级到 GE750。 7T 将取代我们的 3T-C。 Skyra 3T 将在 2011 年 1 月取代我们的 1.5T，GE 升级将在我们购买的 CRADA 扫描仪上进行。 Sean Marrett 和 Vinai Roopchansingh 负责监督这些扫描仪正在进行的建设项目。去年，一位新的科学家 Souheil Inati 加入了我们的团队。他带来了 MR 物理和脉冲编程方面的丰富专业知识以及西门子平台的经验。在过去的一年中，我们创建了一个透明的“技术扫描”列表，允许具有适当资格的个人通过执行“技术扫描”来简化他们的扫描设置和测试过程。此特权需要进行大量编辑和反馈才能准备就绪。关于核心设施的 IT 相关成就：技术人员集中认证 FMRIF 的 8 名 MRI 技术人员的 IT 基础设施已经过彻底检修，以便技术人员能够更轻松地在不同日期支持不同的扫描仪。他们的独立 Windows 工作站已被连接到中央 Xserver 的 iMac 所取代。每个技术人员都可以登录任何扫描仪室中的任何 iMac 并访问其桌面。虚拟化我们已经开始一项重大举措，对 FMRIF 的许多核心计算硬件进行虚拟化。虚拟化有很多好处，包括减少空间和功耗以及增加正常运行时间和可靠性。 FMRIF 网络服务器已转换为虚拟机，我们预计身份验证、备份和 dicom 捕获器将在来年转换。使用统计我们继续扩展扫描计划数据库的会计功能。现在，我们能够生成关于每个调查员如何以及何时使用扫描仪的细粒度报告。例如，今年我们增加了计算调查员在向社区放弃不需要的扫描时间时提供多少通知的功能。这些报告帮助我们和科学总监分配扫描时间，以最大限度地有效利用 FMRIF 资源。最后，在过去的一年里，功能性 MRI 设施继续举办夏季 fMRI/MRI 夏季研讨会系列。这个非正式的 fMRI/MRI 夏季课程主要由 NIH 的研究人员讲授。虽然讲座没有被拍摄，但演示文稿的数字版本已放置在允许下载的网站上。本课程受到 NIH 暑期学生和 IRTA 学士后社区的好评。今年的出席人数大约是去年的两倍。
