IMAGING METHOD AND MEANS FOR COGNITIVE BRAIN SCIENCE BASED ON METAVERSE MIXED REALITY TECHNOLOGY

Smart overview of the Invention

The patent outlines an innovative imaging method for cognitive brain science utilizing metaverse mixed reality technology. This approach aims to create a highly interactive brain function teaching platform, significantly enhancing the efficiency and immersion of medical education, neuroscience research, and clinical training. The method involves several key steps: modeling brain tissue using MRI images, virtual modeling of fiber bundles, optimizing the model, and converting and generating a 3D model.

Technical Field

This method integrates the fields of biomedical science and virtual simulation. It specifically addresses the challenges in teaching and understanding the complex structure and function of the human brain. Traditional methods using 2D displays and 3D printing have limitations in spatial understanding and flexibility. By using mixed reality technology, this invention provides a more comprehensive and interactive learning experience.

Methodology

The process begins with modeling brain tissue based on MRI images, using the marching cubes (MC) algorithm to extract contour surfaces. Next, fiber bundles are virtually modeled by obtaining a spatial transformation matrix and selecting the necessary branches. The model is then optimized using an edge collapse simplification algorithm to reduce the mesh size. Finally, surface reduction processing is performed on the stereolithography (STL) file, converting it into an object file (OBJ), which is then packaged and colored to create a complete model.

Interactive Platform

The invention employs advanced 3D modeling technology to accurately simulate brain structures and nerve fiber bundles. This model is rendered in a mixed reality environment, allowing users to interact with and view brain structures and functions in real-time. The platform also simulates neural signal transmission and functional area activation through color changes, providing a dynamic view of the brain's working state during cognitive tasks.

Applications and Benefits

This method offers a clear, intuitive, and highly interactive platform for teaching and research. It significantly enhances the understanding and application of medical knowledge by providing an immersive experience. The platform is particularly beneficial for medical education, neuroscience research, and clinical training, overcoming the limitations of traditional 2D and 3D methods by offering real-time interaction in a virtual and real environment.
