Acquisition of a High Resolution X-Ray Tomographic Scanner

9406258 Carlson这笔拨款为德克萨斯大学奥斯汀分校购置一台高分辨率、x射线、计算机断层扫描（CT）扫描仪提供部分支持，用于创新的亚毫米尺度的变质结构、脊椎动物古生物学和体质人类学研究。高分辨率CT仪器的最新进展，特别是关于x射线聚焦和模块化探测器设计，以及为跨平台使用而开发的复杂图像处理软件，将允许对许多地质材料进行前所未有的高分辨率、非破坏性的三维成像，这些材料的数字图像将可以快速获得，并且格式易于交换。这些数据将提供给部门间、区域和更远的地方感兴趣的研究人员。该设备将允许分析大量不同样本量的地质材料，因此在变质岩石学和无脊椎古生物学方面有很大的发展潜力，学术研究人员可以获得这些新进展，其成本将大大低于商用的高分辨率CT仪器时间。＊＊＊

9406258 Carlson This grant provides partial support for the acquisition of a high-resolution, X-ray, computed tomography (CT) scanner for innovative, sub- millimeter scale studies of metamorphic textures, vertebrate paleontology and physical anthropology at the University of Texas-Austin. Recent advances in high resolution CT instruments, especially with regard to X-ray focusing and modular detector design, together with sophisticated image processing software developed for cross-platform usage, will allow unprecedented, high resolution, non-destructive 3- D imaging of many geologic materials for which digital will be available both rapidly and in formats that are readily exchangeable. These data will be made available for interested researchers both interdepartmentally as well regionally and further afield. This facility will allow analysis of a wide range of geologic materials of greatly varying sample size and thus has great potential for new advances in metamorphic petrology and invertebrate paleontology that will available to academic researchers at costs which will be substantially below commercially available, high resolution CT instrument time. ***
