ABSTRACT:
A method and an apparatus for the in vivo, non-invasive, early detection of alterations and mapping of the grade of these alterations, causing in the biochemical and/or in the functional characteristics of the epithelial tissues during the development of tissue atypias, dysplasias, neoplasias and cancers is presented. The method is based, at least in part, on the simultaneous measurement of the spatial, temporal and spectral alterations in the characteristics of the light that is re-emitted from the tissue under examination, as a result of a combined tissue excitation with light and special chemical agents. The topical or systematic administration of these agents result in an evanescent contrast enhancement between normal and abnormal areas of tissue. The apparatus enables the capturing of temporally successive imaging in one or more spectral bands simultaneously.
