中文摘要
0948842Ketcham 这笔赠款为德克萨斯大学计算机 X 射线断层扫描 (UTCT) 设施提供三年的持续支持。 UT 的 CT 扫描仪经过专门设计,可对一系列地质材料和样本大小进行 X 射线断层扫描。 该技术是从商用生物医学 CAT 扫描仪发展而来,采用更高能量的 X 射线源和更高分辨率的 CCD 探测器,可以对非生命地质样本进行微米级成像。 该技术可以对样品的外部和内部进行完全无损的成像。 由于沿 X 射线路径的样品密度和材料元素成分的变化而产生的 X 射线衰减差异由 CCD 进行数字记录。 样品安装在 X 射线源前面的旋转台上。 衰减 X 射线的径向二维切片通过样本台的垂直平移进行堆叠。 X 射线结果?正弦图?然后通过计算机算法进行缩减,以呈现样本内密度分布的高分辨率 3D 图像。 通常支持涵盖地球科学、生物学、工程和人类学的研究应用。 来自 UTCT 扫描的数据和图像是可通过网络访问的数据,对于教学非常有用。***
英文摘要
0948842KetchamThis grant provides continued support for the University of Texas Computed X-ray Tomography (UTCT) Facility over a three year period. The CT scanner at UT was specifically designed to enable x-ray tomography of a range of geological materials and sample sizes. The technology was developed from commercial biomedical CAT scanners with the adoption of a higher energy x-ray source and higher resolution CCD detectors to allow micron-scale imaging of non-living geological samples. The technique allows for completely non-destructive imaging of the exteriors and interiors of samples. Differences in x-ray attenuation that occur due to variations in sample density and the elemental composition of the material along the x-ray path are digitally recorded by a CCD. Samples are mounted on a rotating table in front of the x-ray source. Radial 2-d slices of the attenuated x-rays are stacked by vertical translation of the sample table. Resultant x-ray ?sinograms? are then reduced via computer algorithms to render high resolution 3-D images of the density distributions within samples. Research applications spanning the geosciences, biology, engineering and anthropology are routinely supported. Data and images from UTCT scans are web-accessible data and extremely useful for teaching.***
