A method for selective detection, with a thermographic plate, of traces of blood flow that differ from traces with a correct course in vessels at different depths, particularly of the breast, which consists in that a sequence of thermographic images is taken which are acquired by a thermographic plate (LT) gently pressed against the skin, which is cooled before each photograph with an air jet whose duration is correlated to the depth of the portion of vessel being investigated, the traces of vessels with a correct course having a substantially centripetal direction with respect to the breast and tapering toward the center of the organ so as to confirm a temperature of the blood flow which decreases because the vessel gradually branches and because the depth from the surface of the skin increases.
La présente invention concerne un procédé de détection sélective au moyen d'une plaque thermographique de traces de flux sanguin qui diffèrent de traces présentant une course correcte dans des vaisseaux à des profondeurs différentes, en particulier dans la poitrine. Ledit procédé consiste en la prise d'une séquence d'images thermographiques acquises par une plaque thermographique (LT) doucement pressée contre la peau, qui est refroidie avant chaque photographie avec un jet d'air, la durée étant corrélée à la profondeur de la partie du vaisseau examiné. Les traces des vaisseaux présentant une course correcte ont une direction sensiblement centripète par rapport à la poitrine et s'effilent en direction du centre de l'organe, de manière à confirmer une température du flux de sang qui diminue parce que le vaisseau se ramifie progressivement et que la profondeur de la surface de la peau augmente.
