AustinMan and AustinWoman are open source electromagnetic voxel models of the human body, which are developed by the Computational Electromagnetics Group at The University of Texas at Austin. The models are based on data from the National Library of Medicine’s Visible Human Project.

Package overview

AustinManWoman_materials.txt
AustinManWoman_materials_dispersive.txt
head_only_h5.py

Note

  • The main body tissues are described using a 3-pole Debye model, but not all materials have a dispersive description.

  • The dispersive material properties can only be used with the 1x1x1mm or 2x2x2mm AustinMan/Woman models. This is because the time step of the model must always be less than any of the relaxation times of the poles of the Debye models used for the dispersive material properties.

  • head_only_h5.py is a script to assist with creating a model of only the head from a full body AustinMan/Woman model.

How to use the models

The AustinMan and AustinWoman models themselves are not included in the user libraries sub-package.

To insert either AustinMan or AustinWoman models into a simulation use the #geometry_objects_read.

Example

To insert a 2x2x2mm \(^3\) AustinMan with the lower left corner 40mm from the origin of the domain, using disperive material properties, and with no dielectric smoothing, use the command:

#geometry_objects_read: 0.04 0.04 0.04 ../user_libs/AustinManWoman/AustinMan_v2.3_2x2x2.h5 ../user_libs/AustinManWoman/AustinManWoman_materials_dispersive.txt

For further information on the #geometry_objects_read see the section on object contruction commands in the Input commands section.
