PROCÉDÉ POUR ESTIMER DES DÉBITS ET DES GRADIENTS DE PRESSION DANS DES RÉSEAUX ARTÉRIELS À PARTIR DE DONNÉES DE DISTRIBUTION DE CONTRASTE OBTENUES SUR LA BASE D'UNE ANGIOGRAPHIE DE TOMOGRAPHIE ASSISTÉE PAR ORDINATEUR
According to embodiment of the present invention, the present invention provides one kind determines that function severe coronary is narrow for non-intrusion type. This method includes collecting patient-specific data and being related to the concentration of contrast agent to use coronary artery blood vessel computed tomography scan (CCTA) in coronary artery patient. Patient-specific data is used to calculate the coronary artery patient of the patient-specific attenuation gradient through chamber. The specific attenuation gradient through chamber of patient is used for determining the Coronary flow velocity of estimation, barometric gradient, loss coefficient, coronary flow reserve and/or blood flow reserve patient. Coronary flow velocity, barometric gradient, loss coefficient, coronary flow reserve, it is narrow that blood flow reserve can be used for estimation function severe coronary.
