Embodiment Construction

[0154] The inventor noticed during the invention that:

[0155] Existing computer-aided software generally uses geometric measurement methods to evaluate the severity of coronary artery stenosis, but these geometric measurement methods have not been sufficiently optimized, including the inherent limitations and completeness of the model itself, and the simulation of image data by the model. The degree of fit makes its accuracy and reliability affect the performance of evaluating the degree of stenosis currently considered, resulting in doctors needing more subjective and unrepeatable judgments and operations. On the other hand, relying solely on imaging can only evaluate the severity of vascular stenosis in an anatomical sense, and cannot directly capture the physiological effects of stenosis, including hemodynamics, vessel wall kinematics and dynamics, myocardial ischemia and infarction. degree, plaque mechanical strength and stability prediction.

[0156] At present, as a p...

Abstract

The invention discloses a method and device for establishing a coronary artery physiological index relationship, and a method and device for applying a coronary artery physiological index relationship. The method for establishing the coronary artery physiological index relationship comprises obtaining a plurality of human body parameters in a unit of human; determining the coronary artery physiological index of each person in a unit of human; establishing a first corresponding relationship between the plurality of human body parameters and the coronary artery physiological indexes of each person in a unit of human; establishing optimization fusion according to the first corresponding relationship to determine a second corresponding relationship between various physiological parameters andvarious coronary artery physiological indexes; acquiring a plurality of human body parameters of a patient; and determining the coronary artery physiological indexes corresponding to various physiological parameters according to the second corresponding relationship. The optimization fusion method of the invention can evaluate the physiological severity of coronary stenosis more accurately and reliably than a method just using geometric measurement.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a method and device for establishing and applying coronary artery physiological index relationships. Background technique [0002] Coronary heart disease, short for coronary heart disease, is the most common heart disease. Coronary heart disease is a heart disease caused by myocardial ischemia and hypoxia (angina pectoris) or myocardial necrosis (myocardial infarction) caused by coronary artery organic (atherosclerosis or dynamic vasospasm) stenosis or obstruction, also known as ischemia heart disease. [0003] The occurrence of coronary heart disease is closely related to the degree and number of coronary artery atherosclerotic stenosis, while suffering from diseases such as hypertension and diabetes, as well as excessive obesity and bad living habits are the main factors that induce the disease. Coronary heart disease is one of the diseases with the highest mortality rate in...
