DESCRIPTION (provided by applicant): This application is to replace an existing microCAT that already supports multiple NIH-funded projects but is failing and cannot be repaired. The replacement system will support all of the current projects and have higher resolution, faster scan time, and lower radiation dose that will enable new applications, expanding usage to additional research projects. In vivo micro computed tomography systems are used for non-destructive three dimensional analyses of synthetic, ex vivo specimens, and, most importantly, live animals. Two of the four quadrants on our existing microCAT II have failed and cannot be repaired because the manufacturer of that instrument no longer supports parts replacement. The proposed vivaCT80 system is the first and only in vivo microCT system currently available that can produce images at a resolution sufficient for analysis of murine trabecular bone and microvasculature, low radiation dose, and possesses a bore size large enough to accommodate animals as large as small primates. Many current users depend on in vivo microCT for coregistration and attenuation calculations with PET, MRI, and optical CT (FMT, Visen). Hence, the loss of in vivo microCT imaging capabilities will affect multiple imaging platforms and projects across a wide range of biomedical fields. Thus, the vivCT80 will provide years of stable support for existing users and expand numerous, wide ranging, NIH funded projects as well as pilot projects for new users and projects. Supported projects study angiogenesis, skeletal consequences of breast and prostate cancer and multiple myeloma, bone quality, endochondral ossification, Alzheimer's disease, drug development, acute infectious disease, and a range of soft tissue tumors, among others. Aspects of each of these projects either require or will be substantially enhanced by reliable, fast, in vivo microCT imaging. Due to its improved capabilities, the vivaCT80 will undoubtedly foster collaborations within Vanderbilt University and at neighboring institutions. Housing this instrument in the Vanderbilt University Institute for Imaging Science (VUIIS), which has been highly successful in managing numerous imaging modalities, will ensure campus wide access and superior management. Acquisition of a new in vivo microCT is absolutely critical to the continued success of many NIH- funded grants at Vanderbilt.

描述（由申请人提供）：此应用程序用于替换现有的 microCAT，该 microCAT 已支持多个 NIH 资助的项目，但出现故障且无法修复。替代系统将支持所有当前项目，并具有更高的分辨率、更快的扫描时间和更低的辐射剂量，这将实现新的应用，将用途扩大到其他研究项目。体内微型计算机断层扫描系统用于对合成的离体标本（最重要的是活体动物）进行非破坏性三维分析。我们现有的 microCAT II 的四个象限中有两个出现故障且无法修复，因为该仪器的制造商不再支持零件更换。所提出的vivaCT80系统是目前第一个也是唯一一个体内微型CT系统，它可以产生足以分析小鼠骨小梁和微血管系统的分辨率的图像，辐射剂量低，并且具有足够大的孔径，可以容​​纳大到小型灵长类动物。当前许多用户依靠体内 microCT 与 PET、MRI 和光学 CT（FMT、Visen）进行配准和衰减计算。因此，体内 microCT 成像能力的丧失将影响广泛生物医学领域的多个成像平台和项目。因此，vivCT80将为现有用户提供多年的稳定支持，并为新用户和项目扩展众多、广泛的、NIH资助的项目以及试点项目。支持的项目研究血管生成、乳腺癌、前列腺癌和多发性骨髓瘤的骨骼后果、骨质量、软骨内骨化、阿尔茨海默病、药物开发、急性传染病和一系列软组织肿瘤等。这些项目的各个方面都需要可靠、快速的体内 microCT 成像，或者将通过可靠、快速的体内 microCT 成像得到显着增强。由于其改进的功能，vivaCT80 无疑将促进范德比尔特大学和邻近机构之间的合作。该仪器安装在范德比尔特大学成像科学研究所 (VUIIS) 中，该研究所在管理众多成像模式方面取得了巨大成功，将确保校园范围内的访问和卓越的管理。获得新的体内 microCT 对于范德堡大学 NIH 资助的许多资助项目的持续成功绝对至关重要。
