Method and system for non-invasive quantification of tissue perfasion obtainable by a destruction-reperfusion process that provide a signal representative of local agent concentration during reperfusion, by deriving at least one local tissue perfusion value. The system comprises means for adjusting or relating a function of time with S-shape characteristics to the signal proportional to the local agent concentration during reperfusion, and making a correspondence between at least one value of at least one parameter of the function with S-shape characteristics with at least one local tissue perfusion value (such as mean velocity, mean transit time, mean flow, perfasion volume) or attribute (such as the blood flow pattern, flow distribution variance or skewness).

La présente invention concerne un procédé et un système de quantification non invasive de perfusion de tissu qu'on peut obtenir par un processus de destruction-reperfusion qui fournit un signal représentatif de concentration d'agent locale pendant la reperfusion, par le calcul d'au moins une valeur de perfusion de tissu local. Ce système comprend un organe permettant d'ajuster ou de mettre en relation une fonction temporelle dotée de caractéristiques de sinusoïde avec le signal proportionnel à la concentration d'agent locale pendant la reperfusion et, d'établir une correspondance entre au moins une valeur d'au moins un paramètre de cette fonction aux caractéristiques de sinusoïde avec au moins une valeur de perfusion de tissu local (telles qu'une vitesse moyenne, un temps de transit moyen, un débit moyen, un volume de perfusion) ou avec un attribut (telles que la courbe de débit sanguin, la variance de distribution de débit ou l'asymétrie).
