The system comprises an obtaining module, a narrow rate determining module, a model determining module and an FFR calculating module. The obtaining module is used for obtaining three-dimensional image information of the coronary artery, determines distribution information of dragon bone joints of the coronary artery according to the three-dimensional image information of the coronary artery, and obtains information parameters of the dragon bone joints;the narrow rate determining module is used for determining the narrow rate of the coronary artery according to the information parameters of the dragon bone joints of the coronary artery; the model determining module is used for determining an FFR evaluating model according to the relation of the narrow rate of the coronary artery and a preset narrow rate; the FFR calculating module is used for calculating the FFR value of the coronary artery according to the information parameters of the dragon bone joints and the FFR evaluating model.

Description

technical field [0001] The present invention relates to biomedical engineering technology, in particular to a system, method, device and computer-readable storage medium for blood flow reserve fraction. Background technique [0002] Fractional flow reserve (FFR) has now become a recognized index for functional evaluation of coronary artery stenosis, and its most important function is to accurately evaluate the functional consequences of an unknown coronary artery stenosis. The existing non-invasive assessment based on coronary non-invasive angiography (CT angiography, CTA) is based on CTA image reconstruction technology and computational fluid dynamics (Computational Fluid Dynamics, CFD) multi-scale numerical simulation to calculate FFR. The CFD calculation model is complex and often needs to calculate millions of grids. Therefore, it takes a long time and is not suitable for rapid clinical diagnosis. At the same time, due to the large amount of calculation, it needs to be c...

The existing non-invasive assessment based on coronary non-invasive angiography (CT angiography, CTA) is based on CTA image reconstruction technology and computational fluid dynamics (Computational Fluid Dynamics, CFD) multi-scale numerical simulation to calculate FFR. The CFD calculation model is complex and often needs to calculate millions of grids. Therefore, it takes a long time and is not suitable for rapid clinical diagnosis. At the same time, due to the large amount of calculation, it needs to be completed on a workstation or server due to the high performance of the equipment. , resulting in an increase in cost
