SynthAorta Dataset

SynthAorta Dataset

This repository contains the SynthAorta dataset, based on the paper "SynthAorta: A 3D Mesh Dataset of Parametrized Physiological Healthy Aortas". Any new updates or code related to the dataset will be published on the corresponding GitHub repository: https://github.com/domagoj-bosnjak/SynthAorta.

Dataset info

The dataset contains 30,000 synthetic geometries of physiological, healthy aortas, including three supraaortic vessels. Specifically, the dataset contains:

Structured hexahedral meshes; 4 refinement levels with 226, 1,792, 14,336, and 114,688 elements, respectively.

Consistent meshes, with the same node numbering for every example.

Centerlines with local radius data, enabling the recovery of the smooth surface using the convolution surface framework.

Code for outputting the meshes to the .msh file format, easily transferable to other FEM software.

The main parameter file, parameters_SynthAorta.csv, with all described geometric features. All accompanying files provide node-wise radii for different aortic regions. All files are aligned by case number, with consistent skeleton sampling across geometries. Full parameter definitions are available in the related publication.

Note: the dataset contains around 90,000 files in total.

Usage and file formats

All data is stored in binary format for efficiency. For more information, refer to the README.txt file. Minimal MATLAB/Octave code is also uploaded, which handles the input/output of meshes and skeletons, as well as elementary visualizations. The meshes are output in the standard .msh format, which can be parsed/converted by any modern FEM software or library. 

The examples folder contains extracted meshes for initial visualization, requiring the open-source software Gmsh.

这个仓库包含SynthAorta数据集，该数据集基于论文《SynthAorta：参数化生理健康主动脉的三维网格数据集》（arXiv:2409.08635）。任何与该数据集相关的新更新或代码都将发布在对应的GitHub仓库：https://github.com/domagoj-bosnjak/SynthAorta。

数据集信息

该数据集包含30000个生理健康主动脉的合成几何结构，包括三条主动脉弓上血管（supraaortic vessels）。具体而言，数据集包含：

结构化六面体网格（structured hexahedral meshes）；四个细化级别，分别含226、1792、14336和114688个单元。

一致性网格（consistent meshes），每个样本具有相同的节点编号。

含局部半径数据的中心线（centerlines with local radius data），可通过卷积曲面框架（convolution surface framework）恢复光滑表面。

将网格输出为.msh文件格式的代码，可轻松迁移至其他有限元方法（FEM）软件。

使用方法与文件格式

所有数据以二进制格式存储以提升效率，更多信息见README.txt。此外还上传了极简MATLAB/Octave代码，用于网格和骨架的输入/输出及基础可视化。网格以标准.msh格式输出，可被任何现代有限元方法（FEM）软件或库解析/转换。

examples文件夹包含用于初始可视化的提取网格，需使用开源软件Gmsh。

所有反馈均受欢迎，尤其是在使用数据集时遇到问题或故障，请联系我们：[e-mail]或[e-mail]。
