Abstract

La présente invention a pour objet un procédé de détection et de cartographie de zones enflammées de tissus vivants ainsi qu'un dispositif pour sa mise en oeuvre. Procédé caractérisé en ce qu'il consiste à soumettre les tissus à analyser à une excitation lumineuse avec un domaine spectral prédéterminé, à acquérir au moins le signal de fluorescence brute des porphyrines pour une pluralité de points de mesure, et à déterminer, pour chaque point de mesure, l'intensité de fluorescence pour les longueurs d'onde caractéristiques des porphyrines endogènes.
