Abstract:

X-ray computed tomography (CT) has been an important technology in paleontology for several decades. It helps researchers to acquire detailed anatomical structures of fossils non-destructively. Despite its widespread application, developing an efficient and user-friendly method for segmenting CT data continues to be a formidable challenge in the field. Most CT data segmentation software operates on 2D interfaces, which limits flexibility for real-time adjustments in 3D segmentation. Here, we introduce Curves Mode in Drishti Paint 3.2, an open-source tool for CT data segmentation. Drishti Paint 3.2 allows users to manually or semi-automatically segment the CT data in both 2D and 3D environments, providing a novel solution for revisualizing CT data in paleontological studies.

Key words: X-ray computed tomography (CT), 2D and 3D segmentation, 3D reconstruction, Drishti Paint

摘要:

计算机断层扫描(CT)技术在近几十年来被广泛应用于古生物学相关研究领域。研究者借助CT扫描技术可以无损获得化石内部精细信息,进一步对材料进行深入研究。但是,如何对CT数据进行高效的三维分割与重建仍是研究者们在使用三维数据时面临的主要问题。大多数CT数据分割软件都采用二维分割的传统方法,难以直接对三维结果进行实时修正。介绍了三维可视化开源软件Drishti Paint 3.2版本中的曲线模式(Curves Mode)及其使用方法。该软件为研究者提供了同时在二维切片及三维窗口手动或半自动分割CT数据的新工具,为如何对古生物学研究中化石CT数据进行高效的三维分割与重建提供了新思路。
