本文提出了一种模块化、开放式微型 X 射线计算机断层扫描 (mu XRCT) 系统，该系统是在过去几年在斯图加特大学应用力学研究所 (CE) 以及早期在波鸿鲁尔大学计算工程研究所建立的。该系统的特点是其内在的灵活性，这源于每个级别的模块化和开放式设计以及实施高级实验现场设置的机会。一方面，所提出的工作旨在支持有兴趣建立用于材料微观结构表征的实验 XRCT 系统的研究人员。另一方面，它旨在支持那些面临自行建立系统或购买商业扫描仪决定的科学家。除了介绍各种硬件组件和应用的模块化软件概念之外，还通过实施一种简单可靠的方法来补偿不良探测器像素以提高投影的原始数据质量，展示了开放式模块化硬件和软件设计的技术机会。详细研究了所提出的系统在可实现的空间分辨率方面的性能。最后显示并讨论了三种不同应用的 XRCT 数据集，展示了所提出系统的广泛选项。
In this paper, a modular and open micro X-ray Computed Tomography (mu XRCT) system is presented, which was set up during the last years at the Institute of Applied Mechanics (CE) of the University of Stuttgart and earlier at the Institute of Computational Engineering of Ruhr-University Bochum. The system is characterized by its intrinsic flexibility resulting from the modular and open design on each level and the opportunity to implement advanced experimental in situ setups. On the one hand, the presented work is intended to support researchers interested in setting up an experimental XRCT system for the microstructural characterization of materials. On the other hand, it aims to support scientists confronted with the decision to set up a system on their own or to buy a commercial scanner. In addition to the presentation of the various hardware components and the applied modular software concept, the technical opportunities of the open and modular hard- and software design are demonstrated by implementing a simple and reliable method for the compensation of bad detector pixels to enhance the raw data quality of the projections. A detailed investigation of the performance of the presented system with regard to the achievable spatial resolution is presented. XRCT datasets of three different applications are finally shown and discussed, demonstrating the wide scope of options of the presented system.
