1. A method for generating an image of a tissue element, comprising: generating, by a visualization system controller, a highlighting image representation of the tissue element within a tissue region based upon a first image of the tissue element captured when a first light source illuminates the tissue region; receiving, by the visualization system controller, a second image of the tissue element within the tissue region when a second light source illuminates the tissue region; combining, by the visualization system controller, the highlighting image representation of the tissue element to the second image of the tissue element to generate a composite tissue image; and delivering, by the visualization system controller, the composite tissue image to an output device.
