Non-Melanoma skin cancer is a common type of cancer, and early detection is important for successful treatment. Hyperspectral imaging shows promise for non-invasive inspection of skin lesions, with optimal wavelength ranges between 573.45 and 779.88 nm for distinguishing healthy and unhealthy skin, and between 429.16 and 520.17 nm for differentiating cancer types.
Non-Melanoma skin cancer is one of the most frequent types of cancer. Early detection is encouraged so as to ensure the best treatment, Hyperspectral imaging is a promising technique for non-invasive inspection of skin lesions, however, the optimal wavelengths for these purposes are yet to be conclusively determined. A visible-near infrared hyperspectral camera with an ad-hoc built platform was used for image acquisition in the present study. Robust statistical techniques were used to conclude an optimal range between 573.45 and 779.88 nm to distinguish between healthy and non-healthy skin. Wavelengths between 429.16 and 520.17 nm were additionally found to be optimal for the differentiation between cancer types.
