The impact of shape uncertainty on aortic-valve pressure-drop computations: supplementary data files

This data-set represents data that was used in: The impact of shape uncertainty on aortic-valve pressure-drop computations. M.J.M.M. Hoeijmakers, W. Huberts, M.C.M. Rutten, F.N. van de Vosse, 2021. Int. J. Numer. Method. Biomed. Eng. This data-set includes:- Resampled segmentations of 74 aortic valves with no, mild, moderate, or severe aortic stenosis - Corresponding extruded (10R) and un-extruded (0.1R) surface meshes in .vtk format.- *_R0.1.txt: centerline points and normals.- *_R10.txt: centerline points and normals that where used to post-process the computational fluid dynamics results. Computed pressures along the centerline on these planes are written to this file as well. Authors are free to use and explore this data-set for research purposes. For instance these surface meshes can be used to generate volumetric meshes (not included) of the enclosed domain for the purpose of computing the flow field(s).

本数据集为论文《形状不确定性对主动脉瓣（aortic valve）压降计算的影响》（The impact of shape uncertainty on aortic-valve pressure-drop computations）所使用的研究数据，该论文作者为M.J.M.M. Hoeijmakers、W. Huberts、M.C.M. Rutten、F.N. van de Vosse，发表于2021年《国际生物医学工程数值方法期刊》（Int. J. Numer. Method. Biomed. Eng.）。本数据集包含以下内容：
- 74例主动脉瓣的重采样分割结果，涵盖无、轻度、中度及重度主动脉瓣狭窄（aortic stenosis）病变情况
- 对应格式为.vtk的拉伸（10R）与未拉伸（0.1R）表面网格（surface mesh）
- *_R0.1.txt：存储中心线（centerline）点与法向量
- *_R10.txt：存储用于后处理计算流体动力学（computational fluid dynamics）结果的中心线点与法向量，同时该文件还记录了这些平面沿中心线的计算所得压力值

本数据集可供研究者自由使用并开展研究探索。例如，可借助这些表面网格生成封闭区域的体网格（volumetric mesh）（本数据集未包含该体网格数据），以用于流场计算相关研究。
