Overview

TetMesHeads is a dataset providing 516 complete tetrahedral meshes of human heads.

The creation of this dataset is a joint work between the French National Research and Safety Institute for the Prevention of Occupational accidents and Diseases (INRS) and the Goup of Research in Electrical Energy (GREEN) of University of Lorraine.

Goals & interest

Our objective is to provide high-quality meshes of human heads for use in finite element simulations. We want the corresponding dataset to be as small as possible to enable fast downloads and minimize disk space usage.

Therefore, each subject's head corresponds to a single file, allowing users to download only the files that interest them. However, if necessary, they can download the entire dataset from the repository page on data.gouv.

The samples consist of healthy adults of all ages and body types (mostly generated from the IXI dataset) and should be large enough to support potential statistical studies.

As an illustration, the figure below shows the norm of induced electric field (in compact bones) and current density (in the cerebrospinal fluid) of a worker near a power field source (inductor).

To make it easier to select files to download, a file browser in the form of a dynamic table is available on this website; please visit this page to access it.
All our meshes are available on the dataverse Recherche Data Gouv repository: you can access it by clicking here.

The values provide by our dynamic table are also synthesized in this CSV file. The "file ID" in the last column permits to download each file via the command line with the following bash command (replace {file ID} with the corresponding number, and {mesh_name} with the wanted name for the downloaded archive):

1wget https://entrepot.recherche.data.gouv.fr/api/access/datafile/{file ID} -O {mesh_name}.tar.gz
