Assessment of Bandaged Burn Wounds Using Porcine Skin and Millimetric Radiometry.

Area of Science:

• Biophysics
• Medical Imaging
• Materials Science

Background:

• Burn wound assessment is crucial for effective treatment.
• Current methods for assessing burn depth can be invasive and painful.
• Non-contact, objective measurement techniques are needed for burn diagnostics.

Purpose of the Study:

• To investigate the emissivity of porcine skin in the 80-100 GHz band.
• To evaluate the feasibility of using millimeter wave (MMW) radiometry for burn assessment.
• To determine if MMW radiometry can detect burns through dressings.

Main Methods:

• Experimental setup for emissivity measurements of porcine skin.
• Measurements conducted on healthy, burned, and dressed skin samples.
• Application of localized heat treatments to simulate burns.
• Analysis of emissivity data in the 80-100 GHz frequency band.

Main Results:

• Emissivity differences up to ~0.28 observed between healthy and burned skin (uncertainty ±0.005).
• Burn-induced emissivity changes correlated with burn depth.
• Burn signatures were detectable through dressing materials, with slightly higher emissivity in dressed samples.

Conclusions:

• MMW radiometry can non-invasively distinguish between normal and burn-damaged skin.
• The technique shows potential for assessing burn depth and monitoring wounds through dressings.
• MMW radiometry offers a promising non-contact diagnostic tool for burn management.
