Abstract

Ultrasonic Echosignal Applied to Human Skin Lesions Characterization

The paper presents a classification of the healthy skin and the skin lesions (basal cell carcinoma) basing on a statistics of the envelope of ultrasonic echoes. The echoes envelopes distributions were modeled using Rayleigh and [K]-distribution. The distributions were compared with empirical data to find which of them better models the statistics of the echo-signal obtained from the human skin. The results indicated that the [K]-distribution provides a better fit.

Also, a characteristic parameter of the [K]-distribution, the effective number of scatterers ([M]), was investigated. The values of the [M] parameter, obtained for the skin cancer (basal cell carcinoma), were lower as compared to those obtained for the healthy skin. The results indicate that the statistical quantitative ultrasound parameters have a potential for extracting information useful for characterization of the skin condition.
