Clinical electromagnetic brain scanner

Area of Science:

• Biomedical Engineering
• Medical Imaging
• Neurology

Background:

• Stroke is a major global cause of death and disability, necessitating timely diagnosis and continuous patient monitoring.
• Current imaging methods like CT and MRI are not suitable for frequent, onsite use.
• There is a need for portable, non-invasive diagnostic tools for stroke management.

Purpose of the Study:

• To report clinical findings from the first use of a novel electromagnetic imaging (EMI) device in stroke patients.
• To evaluate the accuracy and feasibility of the EMI device for stroke detection and localization.

Main Methods:

• Development of a portable, non-invasive electromagnetic imaging (EMI) device using a headset with an antenna array.
• Application of physics-based and data-driven algorithms for brain mapping and stroke analysis.
• Clinical testing of the EMI device on 50 stroke patients.

Main Results:

• The EMI device achieved 98% accuracy in stroke classification.
• The device demonstrated 80% accuracy in two-dimensional stroke localization.
• The system enables quasi-real-time detection and classification of strokes.

Conclusions:

• The portable EMI device shows high accuracy for stroke classification and localization.
• This non-ionizing, non-invasive technology is suitable for frequent monitoring and onsite diagnosis.
• The device has potential applications in ICUs, emergency departments, and by paramedics for rapid stroke assessment.
