Torso Organ Meshes

<p>High density smooth triangulated organ surfaces derived from the <a href="http://lifesciencedb.jp/bp3d/" target="_blank" rel="noopener">BodyParts3D</a> database by The Database Center for Life Science, and a corresponding labelled tetrahedral mesh of the human torso incorporating the organ surfaces.</p> <p>Organs:</p> <ul> <li>Lungs</li> <li>Heart (wall, without valves) with two blood volumes for left and right side.</li> <li>Trachea and major bronchi lumen (not walls), i.e. air.</li> <li>Major blood vessels (truncated, rounded off): <ul> <li>SVC: Superior Vena Cava (wall)</li> <li>IVC: Inferior Vena Cava (wall)</li> <li>PA: Pulmonary Artery (wall)</li> <li>LSPV: Left Superior Pulmonary Vein</li> <li>LIPV: Left Inferior Pulmonary Vein</li> <li>RSPV: Right Superior Pulmonary Vein</li> <li>RIPV: Right Inferior Pulmonary Vein</li> </ul> </li> </ul> <p>Coordinates are provided in millimetres. Organ shapes were adapted to avoid intersections and increase spacing where necessary. Vessel walls are 2 mm thick.</p> <p>Tetrahedral meshes are provided as Gmsh MSH files.&nbsp;</p> <p>Triangulations are provided as OBJ and binary STL files for individual surfaces. These need to be merged (flipping the normals in the process as appropriate) to create closed surfaces.&nbsp;</p> <p>There are four surfaces per vessel:</p> <ul> <li>outer surface</li> <li>inner surface</li> <li>"ring": a surface connecting inner and outer at a cut between heart wall and vessel wall</li> <li>"cap": a surface closing the inner surface, creating a blood volume</li> </ul> <p>FEM models with electrodes may be generated using <a href="https://eidors3d.sourceforge.net/" target="_blank" rel="noopener">EIDORS</a>.</p>
