The goal of the SFI is to provide non-invasive information about tissue remodeling occurring during melanocytic transition and atypia development in the skin. SFI analyzes the topical staining of the skin surface using the ORL-1 dye to reveal the presence of remodeling in the skin, together with the visible feature characteristics. The system provides a biometric score corresponding to the dye staining, a structural score, and a composite SFI score to quantify the presence of tissue remodeling and the process of melanocytic transition in the skin.
