Creating 3D models from Radiologic Images for Virtual Reality Medical Education Modules

Area of Science:

• Medical Education Technology
• Radiology Visualization
• Virtual Reality Applications

Background:

• Virtual Reality (VR) is increasingly adopted in medicine, particularly for surgical training.
• VR offers potential for anatomy teaching and enhancing radiology education.
• Current methods often involve static 2D images or limited 3D models on desktops.

Purpose of the Study:

• To demonstrate an affordable method for converting 2D radiologic images into interactive 3D models for VR.
• To create VR anatomy modules for enhanced visualization and user interaction.
• To explore the potential of VR in improving anatomical understanding.

Main Methods:

• Utilizing thresholding and segmentation techniques to transform 2D radiologic images into 3D models.
• Developing a VR interface with intuitive controls for model manipulation (rotation, translation) via head tilt and gaze.
• Rendering 3D models of specific anatomical structures (Circle of Willis, Vertebral Aneurysm, Spine, Skull) within the VR environment.

Main Results:

• Four distinct anatomy modules were successfully created and imported into the VR interface.
• Users can interactively explore the 3D anatomical models using head movements and gaze.
• The VR system provides dynamic visualization of complex anatomical structures.

Conclusions:

• Virtual Reality presents a powerful, interactive tool for anatomy education in radiology.
• This approach enhances the learning experience for medical students, residents, and patients.
• Affordable VR applications can significantly improve the understanding of 3D anatomy beyond traditional methods.
