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.
