SynthAorta Dataset

This repository contains the SynthAorta dataset, based on the paper "SynthAorta: A 3D Mesh Dataset of Parametrized Physiological Healthy Aortas" (arXiv:2409.08635). 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 transferrable to other FEM software.

Usage and file formats

All of the data is stored in binary format for efficiency, with more info in the README.txt. Minimal MATLAB/Octave code is uploaded as well, for the input/output of the meshes and skeletons, and elementary visualizations. The meshes are outputted 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.

All feedback is welcome, especially if you run into problems or issues using the dataset; contact us at bosnjak@tugraz.at or gmelito@tugraz.at.
