Mixed Reality and 3D Printing Enhance Neurosurgical Training Models

Why It Matters

This approach offers a more realistic and interactive learning experience for aspiring surgeons, allowing them to practice intricate steps and visualize critical structures that are difficult to represent in traditional training methods. It bridges the gap between theoretical knowledge and practical application, potentially leading to better surgical outcomes.

Key Finding

Combining 3D-printed brain models with mixed reality overlays allows for more comprehensive and realistic training of complex neurosurgical procedures, including visualization of critical anatomical structures and simulation of surgical steps.

Key Findings

• The combined MR and 3D-printed model effectively facilitates advanced training of sequential brain tumor resection skills.
• The model enhances the training of critical steps such as lesion localization, head position planning, and dura opening.
• MR enriches the model by visualizing difficult-to-represent structures like vessels and fiber tracts, and enabling interaction concepts like craniotomy simulation.
• This technology demonstrates potential for intraoperative application of mixed reality.
