A multifunctional helmet for noninvasive neuromonitoring

Area of Science:

• Neuroscience
• Biomedical Engineering
• Medical Technology

Background:

• Noninvasive neuromonitoring is crucial for assessing brain health.
• Current methods often lack simultaneous, continuous, and comprehensive data acquisition.
• Advanced techniques are needed for real-time brain function evaluation.

Purpose of the Study:

• To develop and evaluate a novel helmet-based system for simultaneous, continuous neuromonitoring.
• To integrate multiple noninvasive neuroimaging modalities into a single platform.
• To enable long-term, in-situ monitoring of brain activity and hemodynamics.

Main Methods:

• Simultaneous recording of spontaneous and evoked bioelectrical brain activity using new active electrodes.
• Continuous transcranial Doppler (TCD) sonography with robotic probes and 3D multiscan imaging.
• Near-infrared spectroscopy (NIRS) data acquisition.
• Integration of all sensors and data processing within a helmet construction for prolonged recording periods.

Main Results:

• Successful simultaneous and continuous data acquisition from multiple neuromonitoring parameters.
• Demonstration of a novel helmet-integrated technique for extended recording durations.
• Validation of the combined approach for comprehensive brain state assessment.

Conclusions:

• The developed helmet system offers a promising platform for advanced, noninvasive neuromonitoring.
• This integrated approach facilitates continuous assessment of brain electrical activity and blood flow.
• The technology has potential applications in clinical diagnostics and research.
