The Imaging Technology Group (ITG) at the Beckman Institute, University of Illinois, is purchasing a Skyscan 1172 microtomography instrument (micro-CT). This instrument will provide 5-micron -resolution 3D datasets of the internal structure of samples between 1 and 20 mm (35 x 60 mm at a reduced resolution). To store the datasets, which can be as large as 270 gigabytes (GB) each, a 24-terabyte (TB) tape storage system will be purchased for data archiving, along with a 3.7-TB RAID system for online access. The micro-CT will be integrated into a successful K-12 outreach project called Bugscope.1 ITG has been running the Bugscope project since 1999, allowing children from more than 150 classrooms across the country to remotely control an Environmental Scanning Electron Microscope (ESEM) to image their insect specimens. With the micro-CT, students will not only be able to control an SEM to study their samples, but will also be able to explore images of the internal and external 3D structure of at least one of their specimens during each session. This proposal will benefit at least eleven funded research groups with more than fifty graduate students. The projects of the primary users are focused on the development of self-healing materials through the use of microvascular channels, scaffold structures for artificial bone replacement, microfluidic fibers for optical networks, and the study of bone degradation in micro-gravitational environments. The secondary user projects are varied and include the study of colloidal crystal systems, the microstructure of concrete and masonry materials, the characterization of polymeric and ceramic microscale structures, the condensed matter physics of charged complex fluids, and the archaeology of ancient materials. Micro-CT will be a new technique on campus, and it will provide materials researchers from varying departments with the ability to noninvasively image the internal structure of nearly any sample up to 20 mm in diameter with 5-micron resolution.%%%The Imaging Technology Group (ITG) at the Beckman Institute, University of Illinois, is purchasing a microtomography to provide high-resolution three-dimensional cross-sections of the internal structure of.

伊利诺斯大学贝克曼研究所的成像技术组（ITG）正在购买Skyscan 1172显微断层扫描仪（微型CT）。 该仪器将提供1至20 mm（分辨率降低后为35 x 60 mm）之间样本内部结构的5微米分辨率3D数据集。 为了存储数据集，每个数据集可以高达270千兆字节（GB），将购买一个24 TB的磁带存储系统用于数据存档，沿着一个3.7 TB的RAID系统用于在线访问。1 ITG自1999年以来一直在运行Bugscope项目，使全国150多个教室的儿童能够远程控制环境扫描电子显微镜（ESEM），对他们的昆虫标本进行成像。 使用micro-CT，学生不仅能够控制SEM来研究他们的样品，而且还能够在每次会议期间探索至少一个样品的内部和外部3D结构的图像。 这项提案将使至少11个受资助的研究小组受益，这些研究小组有50多名研究生。 主要用户的项目集中在通过使用微血管通道开发自修复材料，用于人工骨置换的支架结构，用于光学网络的微流体纤维，以及微重力环境中骨降解的研究。 二级用户项目多种多样，包括胶体晶体系统的研究，混凝土和砖石材料的微观结构，聚合物和陶瓷微尺度结构的表征，带电复杂流体的凝聚态物理学以及古代材料的考古学。 Micro-CT将是校园里的一项新技术，它将为来自不同部门的材料研究人员提供非侵入性成像能力，几乎可以以5微米的分辨率对直径达20毫米的任何样品的内部结构进行成像。伊利诺斯大学贝克曼研究所的成像技术小组（ITG）正在购买一种显微断层扫描仪，以提供高分辨率的内部结构三维横截面。该仪器将被纳入一个名为Bugscope的成功的K-12外联项目。 ITG自1999年以来一直在运行Bugscope项目，允许来自全国150多个教室的儿童远程控制环境扫描电子显微镜（ESEM），以拍摄他们的昆虫标本。 学生不仅能够控制扫描电子显微镜来研究他们的样品，而且还能够在每次会议期间探索至少一个样品的内部和外部3D结构的图像。 这项提案将使至少11个受资助的研究小组受益，这些研究小组有50多名研究生。 二级用户项目多种多样，包括晶体系统的研究，混凝土和砖石材料的微观结构，聚合物和陶瓷微观结构的表征，带电复杂流体的凝聚态物理学以及古代材料的考古学。 这项新技术将为来自不同部门的材料研究人员提供非侵入性成像的能力，几乎任何样品的内部结构，直径可达20毫米，分辨率为5微米。
