A system and method for diagnosis of living tissue diseases is described. The system includes a computer device for controlling its operation. An operator control device is coupled to the computer device. A viewing screen is coupled to the computer device for displaying digitized images of the living tissue. The operator, using the control device, selects desired portions of the digitized image for further image enhancement according to a desired image enhancement feature selectable from a plurality of image enhancement features. The image enhancement features include any combination of grey scale stretching, contrast enhancement based on logarithmic histogram equalization, spot enhancement and magnification. The system further includes means for visualization and quantification of micro-calcifications, and means for visualization and quantification of mass spiculations.

La présente invention concerne un système et un procédé de diagnostic des affections des tissus vivants. Le système comprend un ordinateur permettant d'en gérer le fonctionnement. Un organe de commande opérateur est couplé à l'ordinateur. Un écran de visualisation couplé à l'ordinateur permet d'afficher des images numérisées du tissu vivant. Utilisant l'organe de commande, l'opérateur sélectionne les parties voulues de l'image numérisée afin d'y pratiquer des retouches complémentaires grâce à une fonction de retouche d'image sélectionnée parmi plusieurs fonctions de retouche d'image. Les fonctions de retouche d'image comprennent toutes sortes de combinaisons d'étirement de l'échelle des gris, de renforcement du contraste par algorithme d'égalisation à histogramme logarithmique, de mise en valeur et d'agrandissement ponctuel. Le système comporte en outre des organes de visualisation et de dénombrement des microcalcifications, et des organes de visualisation et de dénombrement des spiculations massives.
