Abstract

The embodiment of the invention discloses a blood vessel stenosis rate determination method, device and system and a storage medium, and the method comprises the steps: inputting an initial blood vessel image of a patient and a target blood vessel segmentation image corresponding to the initial blood vessel image into a trained plaque segmentation model, so as to obtain a plaque thermodynamic diagram; determining a plaque extraction template according to the plaque thermodynamic diagram, carrying out plaque extraction on a target image according to the plaque extraction template to obtain plaque segmentation data, wherein the target image is the initial blood vessel image or comprises the initial blood vessel image and the target blood vessel segmentation image; and inputting the plaque segmentation data into a trained stenosis rate analysis model to obtain the stenosis rate of the target blood vessel. The problem that the coronary artery stenosis rate determined by an existing coronary artery stenosis rate determining method is low is solved.

Description

technical field [0001] Embodiments of the present invention relate to the field of medical image processing, and in particular to a method, device, system and storage medium for determining a vascular stenosis rate. Background technique [0002] As one of the important diseases threatening human health, coronary heart disease has received more and more attention. The diagnosis of coronary artery disease relies on the rate of coronary stenosis determined on the basis of initial vessel images. In the existing method for determining the coronary artery stenosis rate, the coronary artery stenosis rate is usually calculated on the coronary artery straightening image of the patient's initial blood vessel image, so as to obtain the patient's coronary artery stenosis rate. Due to the complex structure of the coronary artery, the accuracy of coronary artery straightening is low, which makes the accuracy of determining the coronary artery stenosis rate low. [0003] Therefore, it is...
