Embodiment Construction

[0047] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0048] An embodiment of the present invention provides a method for determining blood flow, which can be applied to electronic devices, figure 1 It is a schematic flowchart of an optional method for determining blood flow in the embodiment of the present invention, such as figure 1 As shown, the determination method of the blood flow may include:

[0049] S101: Reconstruct according to the obtained coronary artery CTA data to obtain a coronary artery with a stenotic lesion, and bridge the coronary artery with a stenotic lesion according to a preset CABG scheme to obtain a coronary artery after CABG;

[0050] At present, after CABG surgery, doctors will use some ultrasonic instruments to measure the real-time blood flow of bridging vessels to obtain the measured value of posto...

Abstract

The embodiment of the invention discloses a blood flow determining method. The blood flow determining method comprises the following steps: obtaining a coronary artery having a stenotic lesion according to obtained data of coronary artery CTA, bridging the coronary artery having the stenotic lesion, obtaining the coronary artery after CABG, determining an optimization formula of blood flow of eachbranch of the coronary artery after the CABG according to obtained end microcirculation impedance of each branch of the coronary artery without a stenotic lesion, data of keel nodes of the coronary artery after the CABG and data of keel nodes of the bridged blood vessels, optimizing the optimization formula based on a preset optimization algorithm and according to an initial value of the blood flow of each branch of the coronary artery after the preset CABG, and obtaining the blood flow of each branch of the coronary artery after the CABG. The embodiment of the invention also discloses the blood flow determining device, an electronic device and a computer storage medium.

Description

technical field [0001] The present invention relates to a rapid determination technology of blood flow before coronary artery bypass grafting (CABG, Coronary Artery Bypass Graft), in particular to a blood flow determination method, device, electronic equipment and computer storage medium. Background technique [0002] The coronary artery (coronary artery) connects the ascending aorta and the myocardium, supplies blood to the myocardium, and the myocardium controls the periodic relaxation and contraction of the heart. If the coronary artery is narrowed, it will cause insufficient blood supply to the myocardium and lead to myocardial infarction. After the stenosis, the myocardium dominated by the blood vessel will be necrotic and irreversible, which will be life-threatening. [0003] At present, patients need to use computed tomographic angiography (CTA, Computed Tomographic Angiography) to determine the stenotic lesion of the coronary artery under the condition that the myoca...
