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 …

Why it's free to use
- Filed June 11, 2004 and granted April 15, 2014. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 11, 2024.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 11, 2026.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
