Laboratory based X-ray micro-CT is a non-destructive testing method that enables three dimensional visualization and analysis of the internal and external morphology of samples. Although a wide variety of commercial scanners exist, most of them are limited in the number of degrees of freedom to position the source and detector with respect to the object to be scanned. Hence, they are less suited for industrial X-ray imaging settings that require advanced scanning modes, such as laminography, conveyor belt scanning, or time-resolved imaging (4DCT). We introduce a new X-ray scanner FleXCT that consists of a total of ten motorized axes, which allow a wide range of non-standard XCT scans such as tiled and off-centre scans, laminography, helical tomography, conveyor belt, dynamic zooming, and X-ray phase contrast imaging. Additionally, a new software tool 'FlexRayTools' was created that enables reconstruction of non-standard XCT projection data of the FleXCT instrument using the ASTRA Toolbox, a highly efficient and open source set of tools for tomographic projection and reconstruction.
基于实验室的X射线显微CT是一种无损检测方法，能够对样品的内部和外部形态进行三维可视化和分析。尽管存在各种各样的商业扫描仪，但它们中的大多数在相对于待扫描物体定位源和探测器的自由度数量上受到限制。因此，它们不太适合需要先进扫描模式的工业X射线成像设置，如分层摄影、传送带扫描或时间分辨成像（4DCT）。我们推出了一种新的X射线扫描仪FleXCT，它总共由十个电动轴组成，可进行各种非标准的XCT扫描，如平铺扫描和偏心扫描、分层摄影、螺旋断层扫描、传送带扫描、动态变焦以及X射线相衬成像。此外，还创建了一个新的软件工具“FlexRayTools”，它能够使用ASTRA Toolbox重建FleXCT仪器的非标准XCT投影数据，ASTRA Toolbox是一组用于断层投影和重建的高效开源工具。
