你能想象当你走过草地时脚下会发生什么吗？你能描述一下它在地下的样子吗？土壤的结构是什么，植物的根在黑暗中是如何分散的？水分在孔隙系统中的分布情况决定了土壤中物质的转化。当您使用X射线计算机断层扫描的潜力来观察，可视化和定量分析土壤时，所有这些问题都可能得到回答。为此，您必须首先获得土壤样本，而且不仅是一个，而是统计相关的大量样本！你最好有一台机器来对土壤进行非破坏性取样。在这里，我们描述了这样一台机器的设置和应用，并显示了我们用这种方法实现的第一次宏观和微观CT扫描。
Can you imagine what happens underneath your feet when you walk across a meadow ? Can you describe how it looks like underground ? What is the structure of the soil, how do the plant roots disperse in the dark ? How is the water distributed within the pore system, which in turn determines matter transformation in soil ? All these questions might be answered when you use the potential of X-ray computed tomography to look into, visualize and quantitatively analyze the soil. For that purpose, you must have soil samples first, and not only one, but a statistically relevant large number of samples! You better have a machine for the non-destructive sampling of soil. Here, we describe the setup and the application of such a machine and show the first macro-and micro-CT scans which we achieved with this method.
