The article reports on the development of a new laser technology by the researchers at Duke University in North Carolina. The laser-based system can produce three-dimensional images of the cellular and structural makeup of a lesion, assisting physicians in a more precise diagnosis of a given lesion without classic histologic evaluation. Doctor Warren S. Warren said that the method uses a delicate interplay between two laser beams, each emitting a different color of light.
