Abstract[English]
A method includes acquiring, by one or more processing circuits, intravascular data, the intravascular data including a plurality of pressure measurements measured at a location within a blood vessel by an intravascular instrument, and determining, by the one or more processing circuits, a mean transit time parameter based on the plurality of pressure measurements. The mean transit time parameter is indicative of a mean transit time corresponding to a flow rate of blood in the blood vessel.[French]
La présente invention porte sur un procédé qui comprend l'acquisition, par un ou plusieurs circuits de traitement, de données intravasculaires, les données intravasculaires comprenant une pluralité de mesures de pression mesurées à un emplacement à l'intérieur d'un vaisseau sanguin par un instrument intravasculaire, et la détermination, par le ou les circuits de traitement, d'un paramètre de temps de transit moyen sur la base de la pluralité de mesures de pression. Le paramètre de temps de transit moyen indique un temps de transit moyen correspondant à un débit de sang dans le vaisseau sanguin.
