Projection of realistic three-dimensional photogrammetry models using stereoscopic display: A technical note.

Area of Science:

• Medical Education
• Neuroanatomy
• Surgical Training

Background:

• Traditional surgical laboratories and dissection courses face limitations in some institutions.
• 3D stereoscopy and photogrammetry offer potential solutions for neuroanatomy and neurosurgical education.

Purpose of the Study:

• To describe the combination and setup of realistic 3D models acquired via photogrammetry for stereoscopic projection.
• To evaluate the utility of this combined technique in neuroanatomy instruction.

Main Methods:

• Photogrammetry scans were performed on three donors: a dry skull, an embalmed brain, and an embalmed head.
• The free software Blender was used to process scans and set up stereoscopic projections (red cyan and side-by-side modes).

Main Results:

• Realistic 3D models with depth perception and 360° visualization were successfully created.
• The stereoscopic projection effectively highlighted anatomical details, including cavities and fossae.

Conclusions:

• Combining photogrammetry and 3D stereoscopic techniques is crucial for effective neuroanatomy education.
• Stereoscopic projections offer a valuable, accessible tool for clinical trainees, particularly when laboratory access is restricted.
