Creating Virtual Models and 3D Movies Using DemoMaker for Anatomical Education

Area of Science:

• Medical Education
• Anatomical Visualization
• Virtual Reality in Healthcare

Background:

• Three-dimensional (3D) anatomy models are established educational tools in health professional schools.
• The COVID-19 pandemic accelerated the adoption of virtual technology for online teaching.
• Existing methods for creating 3D anatomical content can be complex and require specialized training.

Purpose of the Study:

• To describe a project developing virtual 3D anatomical models of organs and structures.
• To detail the process of creating 3D movies using specific software (DemoMaker).
• To demonstrate a simplified approach to 3D model reconstruction and animation for educational use.

Main Methods:

• Utilized Amira® software and computed tomographic angiography (CTA) data to generate 3D models.
• Employed volume and surface segmentation techniques on multiple CTA slices for anatomical identification.
• Developed 3D movies and animations for stereoscopic display and integration into lectures.

Main Results:

• Successfully reconstructed 3D models of various organs (lungs, heart, liver, stomach, kidney).
• Established a simplified workflow for creating 3D animations and movies with minimal training.
• Demonstrated the feasibility of displaying 3D models stereoscopically and integrating 3D movies into digital learning platforms.

Conclusions:

• Virtual 3D anatomy models and movies are effective tools for self-directed and classroom-based learning.
• 3D visualizations improve students' understanding of anatomical positions and spatial relationships.
• This approach has the potential to enhance anatomical information retention compared to traditional methods.
