摘要：
1. A method comprising the steps of: estimating the volumetric output of stenosis of blood flow rate based on the effective diameter or radius at the output of stenosis diameter or radius at the inlet of stenosis and volumetric flow rate at inlet stenoses, assess the resistance of stenosis based on stenosis intraaortic pressure inlet output volume flow rate and the coarse simulation computer fluid dynamics metric classify unknown fractional flow reserve to the heart vessel and stenosis as one of a plurality of different predetermined classes on the basis of the extracted features and model learning, the extracted features include one or more of the estimated boundary conditions stenosis, including at least one thing the evaluation output volume velocity blood or evaluation output resistance stenosis and generating a signal indicative of klassifikatsiyu.2. A method according to claim 1, wherein the classification includes generating a numerical value for the unknown KGF, and wherein the method further comprises the step of:. classify unknown metric fractional flow reserve based on numerical znacheniya.3. A method according to Claim. 1, wherein the attributes include something to one or more of the percent stenosis length stenosis, the distance between the aorta and stenosis, the position of stenosis, the size of the heart chambers, myocardial mass, coronary artery geometry, the center line of the coronary artery. 4. A method according to claim. 3, wherein the attributes include something to one or more of the subset of voxels corresponding to the set of interest intensities1. Способ, содержащий этапы, на которых:оценивают выходную объемную скорость кровотока стеноза на основании эффективного диаметра или радиуса на выходе стеноза, диаметра или радиуса на входе стеноза и объемной скорости кровотока на входе стенозаоценивают сопротивление стеноза на основании внутриаортального давления на входе стеноза, выходной объемной скорости кровотока и грубого имитационного модел
