Three-dimensional (3D) analysis is an essential tool to obtain quantitative results from 3D datasets. Considerable progress has been made in 3D imaging techniques, resulting in a growing need for more flexible, complete analysis packages containing advanced algorithms. At the Centre for X-ray Tomography of the Ghent University (UGCT), research is being done on the improvement of both hardware and software for high-resolution X-ray computed tomography (CT). UGCT collaborates with research groups from different disciplines, each having specific needs. To meet these requirements the analysis software package, Morpho+, was developed in-house. Morpho+ contains an extensive set of high-performance 3D operations to obtain object segmentation, separation, and parameterization (orientation, maximum opening, equivalent diameter, sphericity, connectivity, etc.), or to extract a 3D geometrical representation (surface mesh or skeleton) for further modeling. These algorithms have a relatively short processing time when analyzing large datasets. Additionally, Morpho+ is equipped with an interactive and intuitive user interface in which the results are visualized. The package allows scientists from various fields to obtain the necessary quantitative results when applying high-resolution X-ray CT as a research tool to the nondestructive investigation of the microstructure of materials.
三维（3D）分析是从 3D 数据集获取定量结果的重要工具。3D 成像技术取得了相当大的进展，因此对更灵活、更全面的分析软件包的需求不断增加，其中包含先进的算法。在根特大学（UGCT）的 X 射线断层摄影术中心，研究人员致力于改进高分辨率 X 射线计算机断层扫描（CT）的硬件和软件。UGCT 与来自不同学科的研究小组合作，每个小组都有特定的需求。为了满足这些要求，开发了内部分析软件包 Morpho+。Morpho+ 包含一整套高性能的 3D 操作，用于获取对象分割、分离和参数化（方向、最大开口、等效直径、球形度、连通性等），或提取 3D 几何表示（表面网格或骨架）以进行进一步建模。当分析大型数据集时，这些算法的处理时间相对较短。此外，Morpho+ 配备了一个交互和直观的用户界面，可以在其中可视化结果。该软件包允许来自不同领域的科学家在将高分辨率 X 射线 CT 作为研究工具应用于材料微观结构的无损研究时，获得必要的定量结果。
