Electromagnetic Imaging for Breathing Monitoring.

Area of Science:

• Biomedical Engineering
• Medical Physics
• Respiratory Physiology

Background:

• Non-invasive methods for internal organ assessment are crucial.
• Electromagnetic sensing leverages differences in dielectric permittivity between tissues and air.
• Breathing alters lung dielectric permittivity, affecting electromagnetic signals.

Purpose of the Study:

• To explore electromagnetic sensing for non-invasive respiratory system assessment.
• To demonstrate the feasibility of measuring electromagnetic signal changes during breathing.
• To visualize lung function using dynamic imaging.

Main Methods:

• Utilized an experimental device with eight transmitting and receiving antennas.
• Positioned antennas on opposite sides of the chest.
• Recorded changes in electromagnetic radiation passing through the body during respiration.

Main Results:

• Successfully recorded changes in electromagnetic signal levels corresponding to breathing.
• Demonstrated the capability to generate "pulmonograms" from the data.
• Visualized the dynamic, two-dimensional process of lung air-filling.

Conclusions:

• Electromagnetic sensing is a viable non-invasive technique for respiratory monitoring.
• The developed method allows for visualization of lung function.
• This technology holds potential for improved respiratory diagnostics.
