Capture and analysis of autofluorescence in biological tissues for identification and demarcation of lesions.

In certain cell types substances called Chromophores are found. These substances are responsible of a particular way to the incidence of a specific light. Specifically, chromophores are responsible for the autofluorescence of certain cells. This work shows how the use of lighting techniques and image filtering take advantage of these properties in order to distinguish, even in tissues formed by the same cells, disturbances that are not perceptible under standard lighting conditions.In the paper, we explain how these techniques could improve certain surgical procedures, allowing the surgeon to have more complete and detailed information during the intervention itself.
