Human airway geometry (Upper–G16) in STL format

This dataset provides a three-dimensional human airway geometry extending from the upper airway to the 16th generation of bronchial branching. The airway from the upper airway to the 8th generation was reconstructed from anonymized human CT imaging data. No patient-identifiable information is included in this dataset. The geometry has been processed, segmented, and surface-smoothed for CFD simulation purposes. From the 9th to the 16th generation, distal airways were spatially compensated using artificial tubular extensions following the morphometric structure of the Weibel lung model, in order to approximate realistic branching continuity while maintaining computational feasibility. This airway geometry was developed at the ITO research group, Faculty of Engineering Sciences, Kyushu University, Japan.http://www.phe-kyudai.jp/ Intellectual property of the processed airway geometry belongs to the laboratory. The dataset is shared for academic and non-commercial research purposes to promote reproducibility in computational airway modeling studies. Users of this dataset are requested to cite the associated publication when using the model for CFD, deposition, or transport simulations.本数据集提供了从人体上呼吸道延伸至第16代支气管分支的三维气道几何模型。 本数据集内上呼吸道至第8代的气道结构，源自去标识化的人体计算机断层扫描（Computed Tomography, CT）成像数据，且未包含任何可识别患者身份的信息。该气道几何模型已针对计算流体动力学（Computational Fluid Dynamics, CFD）仿真需求完成处理、分割与表面平滑操作。 第9至16代远端气道则参考韦贝尔肺模型(Weibel lung model)的形态计量学结构，通过人工管状延伸进行空间补偿，以在保证计算可行性的前提下，还原真实的分支连续性。 该气道几何模型由日本九州大学工程科学学院ITO研究团队开发，相关网址为：http://www.phe-kyudai.jp/ 经处理的气道几何模型的知识产权归该实验室所有。本数据集仅用于学术与非商业研究，旨在推动计算气道建模领域研究的可复现性。 若使用者将该模型用于CFD、沉积或输运仿真研究，请引用相关发表文献。
