MRI Synthetic Brain Generator

About the Simulator

This interactive web application generates and displays highly detailed, visually convincing synthetic Magnetic Resonance Imaging (MRI) data of a human brain. The simulator is designed as an advanced educational tool to help users explore brain anatomy and MRI principles. The synthetic data is generated algorithmically in real time, with all anatomical features and simulated pathologies scaled proportionally to the selected resolution. This ensures a consistent and accurate experience at all quality levels. The model does not represent a real patient scan, but provides a realistic illustration of the three primary anatomical planes: Axial, Coronal, and Sagittal.

Key Features: The synthetic brain includes anatomically accurate cerebrum, cerebellum, brainstem, detailed gray and white matter with complex gyri and sulci, a realistic ventricular system, subtle subcortical structures, and an optional simulated pathology. All features are generated proportionally for any selected resolution, so the appearance remains correct at Very Low, Medium, or Very High settings. The application is fully self-contained and runs entirely in your browser.

How to Use

You can explore the synthetic brain model using your mouse, keyboard, touch, and the interactive controls provided. All features and controls are described below:

• Axial, Coronal, Sagittal Buttons: Switch between the three main anatomical planes. The currently selected view is highlighted.
• Show Pathology / Show Healthy: Toggle between a healthy brain and one with a simulated lesion. The pathology is generated and positioned proportionally for the current resolution.
• Play Demo: Starts an automated demonstration that cycles through views and slices.
• Audio Toggle: Turns sound effects for slice changes on or off. Audio is off by default for a quiet experience.
• Resolution Dropdown: Choose between Very Low (64), Medium (128), and Very High (256) resolutions. All anatomical features and pathologies are scaled to match the selected resolution, so the appearance remains correct at any setting. Medium is selected by default for a balance of speed and detail.
• Slice Navigation:
  • Mouse: Click and drag vertically on the canvas to scroll through slices.
  • Keyboard: Use the Up/Down arrow keys to change slices.
  • Touch: Swipe up or down on the canvas.

The info overlay below the canvas displays the current view, slice number, and resolution.

Future Directions

This simulator now supports dynamic resolution scaling and proportional feature generation, making it more accessible and accurate across devices. Future enhancements could include:

• Even More Detailed Anatomy: Adding specific subcortical nuclei, fiber tracts, and other intricate brain structures.
• Multiple Pathology Types: Simulating a wider range of lesions (e.g., stroke, hemorrhage, multiple sclerosis) with different appearances and effects.
• Integration with Real Atlas Data: Aligning the synthetic model with standard brain atlases for anatomical labeling and educational overlays.
• Parameter Control: Allowing users to adjust parameters of the synthetic data generation to explore different anatomical variations or pathology characteristics in real time.
• Performance Optimizations: Further improving speed and responsiveness, especially for high resolutions, possibly with progressive loading or on-demand slice generation.
