The system, method, equipment and storage media of the blood flow reserve score

Abstract

Embodiments of the present invention disclose a system, method, device, and computer-readable storage medium for evaluating fractional blood flow reserve, wherein the system includes: an acquisition module configured to acquire three-dimensional image information of coronary arteries, according to the coronary arteries The three-dimensional image information of the artery determines the distribution information of the keel nodes of the coronary arteries, and obtains the information parameters of the keel nodes; the stenosis rate determination module is used to determine the stenosis rate of the coronary arteries according to the information parameters of the keel nodes of the coronary arteries The model determination module is used to determine the model for evaluating the FFR according to the relationship between the stenosis rate of the coronary artery and the preset stenosis rate; the FFR calculation module is used to calculate the FFR value of the coronary artery based on the keel node information parameters and the evaluation FFR model.

Description

technical field [0001] The present invention relates to biomedical engineering technology, and in particular, to a system, method, device and computer-readable storage medium for fractional blood flow reserve. Background technique [0002] Fractional flow reserve (FFR) has now become a recognized index for the functional evaluation of coronary stenosis, and its most important function is to accurately evaluate the functional consequences of an unknown coronary stenosis. Existing non-invasive evaluation based on coronary non-invasive angiography (CT angiography, CTA) is based on CTA image reconstruction technology and computational fluid dynamics (Computational Fluid Dynamic, CFD) multi-scale numerical simulation to calculate FFR, however, in this evaluation process. 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 ...

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
