Figure 2From: Evaluation of a low-cost, portable imaging system for early detection of oral cancerWhite light images (left column) and fluorescence images (right column) of typical lesions with OSF (top row) and melanosis (bottom row). Areas with OSF show slightly increased green fluorescence. Melanosis is easily recognizable from the dark pigmentation in the white light image, and is associated with loss of fluorescence.Back to article page
