3D Interactive
Human Anatomy

3D Interactive Human Anatomy at Ohio University. This page presents interactive 3D visualizations of human anatomical structure. Our team has been visualizing human anatomical structure based on CT scanning since 2006, and some of our work on a dried skull (OUVC 10503) was published in 2008 . Additional materials will be added. The project is led by Lawrence Witmer and Ryan Ridgely , and Ridgely has done all of the segmentation, 3D visualization, and animation. Movies have been labeled and 3D PDFs have been assembled by William Porter , Ashley Morhardt , and Jason Bourke .
Visualizations of human arms. In 2008, we had the opportunity to inject the upper extremity blood vessels of a fresh (unfixed) cadaver of a white male in his 50s named Frank. Arteries and veins received different injection media, a WitmerLab technique known as Differential-Contrast Dual-Vascular Injection (DCDVI) . The injection process was led by Donald Kincaid, Director of the OU-HCOM Body Donor Program , and assisted by Witmer , Ridgely , Dave Dufeau , and Porter . The injected arms were then CT scanned on a General Electric LightSpeed Ultra Multi-Slice CT scanner with the assistance of Heather Rockhold, RT, at O’Bleness Memorial Hospital, Athens, Ohio, with a slice thickness of 625 μm at 120 kV and 200 mA. Ridgely did all of the analysis, segmentation, and 3D visualization in Amira, Maya, and QuickTime, under consultation with Witmer. Labeling of frames was done by Ashley Morhardt and William Porter.

Visualizations of human skull. A human skull (OUVC 10503) was CT scanned on a General Electric LightSpeed Ultra Multi-Slice CT scanner with the assistance of Heather Rockhold, RT, at O’Bleness Memorial Hospital, Athens, Ohio, with a slice thickness of 625 μm at 120 kV and 200 mA. The brain endocast, labyrinth of the inner ear, paranasal sinuses, and paratympanic sinuses were segmented by Ryan Ridgely in Amira and visualized using Maya and QuickTime. This work was initially published in 2008 in The Anatomical Record as part of a larger study on the nasal cavity and sinuses of dinosaurs.
