Abstract
The study of the optical properties of the skin has lead to the identification of the main chromophores such as hemoglobin and melanin. Melanin is a chromophore of the skin, whose accumulation in its different layers defines the types of melanocytic lesions (nevus). In order to achieve the reconstruction of acquired melanocytic lesions, the optic tomography of multispectral skin images was constructed by using a plugin created under the ImageJ environment. This plugin demonstrates the iconographic overlap of images, by capturing segmented images (by multispectral bands), called the multispectral cube of the skin. This 3D image allowed to verify the location of the main chromophores of each layer by its relation to the histopathological location. With this method, the melanin pigment localization patterns (melanin nests) were defined in real time and the structural alterations of nevic skin lesions, that would otherwise not be visible without biopsy, could be defined. The method we present has been shown very useful for locating the chromophores of the skin.
