A Prototype Microwave System for 3D Brain Stroke Imaging.

Area of Science:

• Biomedical Engineering
• Medical Imaging
• Microwave Technology

Background:

• Monitoring patients after stroke onset is crucial for assessing therapy effectiveness.
• Current methods may lack the ability to provide continuous or detailed follow-up.
• There is a need for non-invasive tools for real-time stroke monitoring.

Purpose of the Study:

• To present and characterize a novel microwave imaging prototype for brain stroke monitoring.
• To provide clinicians with a tool for evaluating post-stroke therapy efficacy.
• To demonstrate the potential of differential microwave imaging for stroke detection.

Main Methods:

• Development of a low-complexity helmet prototype with strategically placed antennas.
• Utilization of a differential imaging approach for enhanced contrast.
• Characterization of the prototype's performance using a 3D phantom.

Main Results:

• The prototype successfully generated 3D images of a spherical target mimicking a stroke.
• The target, with a radius of 1.25 cm, was accurately depicted in phantom experiments.
• Preliminary results confirm the potential of the microwave technology for stroke imaging.

Conclusions:

• The developed microwave imaging system shows promise for non-invasive post-stroke monitoring.
• This technology can potentially aid clinicians in managing stroke patient follow-up and therapy.
• Further research is warranted to validate the system in clinical settings.
