Abstract

The invention provides a detection method of a guide wire-free FFR, a guide wire-free IMR and a guide wire-free CFR. The method comprises the following steps: acquiring a 2D coronary image of a blood vessel to be measured; constructing a 3D blood vessel model according to the 2D coronary artery image; acquiring the central arterial pressure of the blood vessel to be measured by using a non-invasive measurement method; constructing a 3D coronary CFD model of the blood vessel to be measured at least according to the 3D blood vessel model and the central arterial pressure; and calculating a guidewire-free CFR, a guidewire-free FFR and a guidewire-free IMR according to the 3D coronary CFD model. The non-invasive detection of CFR, FFR and IMR by adopting a DSA image auxiliary technology is realized.

Description

technical field

[0001] The present application relates to the field of coronary artery physiology, in particular, to a detection method, device, computer-readable storage medium and processor for wire-free FFR, wire-free IMR and wire-free CFR. Background technique

[0002] Coronary artery physiology plays an increasingly important clinical role in cardiology. Fractional Flow Reserve (FFR for short), Index of Microcirculatory Resistance (IMR for short), and Coronary Flow Reserve (CFR for short) are the most commonly used functional indicators to characterize the degree of coronary artery disease. core indicators. They are widely used to evaluate functional ischemia caused by coronary artery stenosis (assessed by FFR), microvascular ischemia without obvious obstruction (assessed by IMR), and coronary system ischemia including epicardial vessels and microvessels (assessed by FFR). CFR assessment). Fractional flow reserve (FFR) calculates the flow reserve capacity of that ves...
