## Core Methodology

### Problem

Standard MRI requires subjects to remain stationary, preventing studies of brain networks during natural movement (e.g., vestibular function, locomotion).

### Key Innovation: mMRI System

Move the **entire imaging system** (magnet + gradients + RF coil) together with the subject:
- **Compact cryogen-free superconducting magnet** — no liquid helium dependency
- **Pneumatically actuated tilt mechanism** — moves the entire system as a unit
- **Minimizes relative motion** between subject and scanner during movement
- Maintains imaging during repetitive tilting motion

### Experimental Validation

- Phantom scans during motion — characterized tilt-induced field shifts
- In vivo rat brain scans during repetitive tilting
- Partially reduced motion and field-shift artifacts

### Applications

- **Vestibular function studies**: Image brain networks that sense head motion
- **Naturalistic paradigms**: Study neural correlates of movement
- **Broadening access**: Lower barrier to naturalistic neuroscience

## Technical Challenges

1. **Tilt-induced field shifts**: Gravity affects superconducting magnet homogeneity
2. **Residual subject-scanner motion**: Imperfect coupling introduces artifacts
3. **Pneumatic actuation**: Vibration and acceleration noise

## Future Directions

- Human-scale mMRI systems
- Integration with functional imaging (fMRI) during movement
- Combined with EEG/MEG for multi-modal moving neuroimaging
