Early Detection of Skin Disorders and Diseases Using Radiometry.

Area of Science:

• Biomedical Engineering
• Dermatology
• Radiophysics

Background:

• Skin diseases significantly impact health and quality of life.
• Current diagnostic methods are invasive, time-consuming, and stressful.
• There is a need for automatic, non-invasive skin disease diagnostic methods.

Purpose of the Study:

• To propose millimeter-wave (MMW) radiometry as a non-contact sensor for non-invasive skin disease diagnosis.
• To evaluate the efficacy of MMW radiometry in distinguishing between healthy and diseased skin.
• To explore the potential for early detection of skin disorders using MMW radiometry.

Main Methods:

• Utilized 90 GHz millimeter-wave (MMW) radiometry for reflectance measurements.
• Conducted measurements on two groups: 60 healthy participants and 60 participants with skin conditions (BCC, SCC, burns, eczema).
• Analyzed radiometric reflectance differences between healthy and unhealthy skin regions.

Main Results:

• Substantial differences in reflectance (0.02-0.27) were observed between healthy and diseased skin.
• MMW radiometry successfully identified and distinguished between healthy and diseased skin areas on the same individual.
• The technique demonstrated potential for differentiating various skin conditions.

Conclusions:

• Millimeter-wave (MMW) radiometry is a promising non-contact sensor for non-invasive skin disease diagnosis.
• This technology can effectively differentiate healthy from diseased skin, aiding in early detection.
• MMW radiometry offers a faster, less stressful alternative to traditional diagnostic methods.
