Abstract

The invention provides a coronary artery capillary resistance index acquiring method, a medium and equipment. The coronary artery capillary resistance index acquiring method includes the steps: coronary artery images are obtained, wherein the coronary artery images comprise images obtained by continuously scanning a target object many times within a period of time after a contrast agent is injected into the target object; according to developing states of the contrast agent, a start frame and a stop frame of the coronary artery images are recognized; according to the start frame, the stop frame and scanning parameters, contrast agent conduction time is calculated; aortic pressure is obtained, and according to the aortic pressure, epicardium coronary artery distal pressure is calculated; and according to the epicardium coronary artery distal pressure and the contrast agent conduction time, a coronary artery capillary resistance index is acquired. The coronary artery capillary resistanceindex acquiring method is easy to implement and does not rely on complex high-value consumables, no complex operation needs to be done by doctors, and large-scale application of IMR in clinical use can be achieved.

Description

technical field [0001] The invention belongs to the field of heart and blood vessel measurement, and relates to a method for obtaining a microvascular resistance index, in particular to a method, medium and equipment for obtaining a coronary microvascular resistance index. Background technique [0002] The blood supply of the myocardium comes from the left and right coronary arteries at the root of the aorta, through coronary branches, coronary microvessels, and venules, and finally enters the right atrium through the coronary sinus or precardiac veins, and the coronary arteries in the epicardium often have vertical branches Branches medially through the myocardium, or branches perpendicularly through the myocardium in the endocardium. In recent years, with the rapid development of evidence-based medicine and interventional cardiology, the clinical significance of coronary microvascular disease has been paid more and more attention. In the process of diagnosis and treatment...
