Progress in skin cancer diagnosis using multispectral imaging

In skin cancer lesions, chromophores such as melanin, hemoglobin, and water might differ among tumors of different etiologies. These differences can be clinically identified when a lesion changes its color, increases its size or thickness, and gets an unusual texture or its outline becomes irregular. In this context, multispectral imaging systems provide precise quantification of spectral, colorimetric, and spatial features of skin cancer lesions.

One of the research lines at CD6 in recent years has been the development and adaptation of optical techniques to improve skin cancer diagnosis. Advances have been achieved by using multi-spectral imaging techniques in the extended near-infrared spectrum (exNIR, 900-1400nm) as well as visible. The use of wavelengths in the exNIR band allows obtaining information from deeper skin  layers and thus, help improving the diagnosis of this type of lesions.
