Visual inspection is still very important for medical diagnosis. New technologies allow the visualization of hidden properties of light which is reflected from the tissue. Fluorescence originating from endogenous tissue components as well as from externally applied dyes allows the visualization of malignant changes at the tissue surface. An interferometric imaging technology, optical coherence tomography (OCT), and laser scan microscopy can even visualize subsurface structures. OCT shows gross tissue structures, e.g. epithelial thickness, tissue homogeneity, tissue scattering, and vessels. In vivo microscopy can even resolve subcellular structures. In addition to diagnosis, optical technologies provide a means for precision treatment without contact.
