Method and device for obtaining average blood flow and flow rate at outlet of coronary artery, and system

Abstract

The application provides a method and device for obtaining average blood flow and flow rate at an outlet of a coronary artery, and a system. The method for obtaining the average blood flow at the outlet of the coronary artery in a cardiac cycle comprises the following steps of in one cardiac cycle, according to the volume of cardiac muscles, obtaining the total blood flow of an inlet of the coronary artery; extracting the blood vessel diameter of each of all the outlets of a corona arterial tree; and according to the total blood flow at the inlet of the coronary artery and the blood vessel diameter of the outlet of the coronary artery, obtaining the average blood flow at the outlet of the coronary artery in the cardiac cycle. The method disclosed by the application is a new non-invasive detection means, measuring the blood flow does not need to rely on a coronary artery ultrasonic technique, and according to the total blood flow at the inlet of the coronary artery and the blood vesseldiameter at the outlet, the average blood flow at the outlet of the coronary artery in one cardiac cycle can be obtained, so that the operation is easy, fine structure images can be distinguished, andthe measuring is more accurate.

Description

technical field [0001] The invention relates to the technical field of coronary artery medicine, in particular to a method, a device, a coronary artery analysis system and a computer storage medium for obtaining the average blood flow and the average blood flow velocity at the outlet of a coronary artery within a cardiac cycle. Background technique [0002] According to the statistics of the World Health Organization, cardiovascular disease has become the "number one killer" of human health. In recent years, the use of hemodynamics to analyze the physiological and pathological behavior of cardiovascular diseases has also become a very important means for the diagnosis of cardiovascular diseases. [0003] Blood flow and flow velocity are very important parameters of hemodynamics. How to measure blood flow and flow velocity accurately and conveniently has become the focus of many researchers. [0004] There are two ways to measure blood flow velocity: non-invasive and invasiv...
