Problems solved by technology

However, for some relatively narrow or severely blocked blood vessel segments, coronary angiography is also difficult to clearly display them. Generally, doctors predict the direction of relatively narrow or severely blocked blood vessel segments based on experience.
The direction of the blood vessel segment predicted based on experience will inevitably deviate greatly from the actual direction of the blood vessel segment, which is very unfavorable to the treatment process of blood vessel dredging

Embodiment Construction

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some, not all, embodiments of the application. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0029] Application overview

[0030] Chronic total occlusion (CTO) refers to a lesion in which there is no forward blood flow in the coronary arteries of the heart that is completely or almost completely occluded for more than 12 weeks. About 20% of the coronary cases diagnosed after angiography belong to CTO. The perfusion of distal myocardial blood flow in CTO lesions is completely dependent on collateral circulation. A good collateral circulation can meet the perfusion demand of the myocard...

Abstract

The present application provides a method for predicting the direction of coronary vessels, a method for training a prediction model, and a device. The method for predicting the direction of coronary vessels includes: using an image segmentation model to segment the coronary artery region in a coronary angiography image to obtain Segmenting the image: using at least one prediction model to predict the direction of the occluded blood vessel segment and / or the narrowed blood vessel segment in the segmented image, so as to obtain at least one predicted image. The technical solution of the present application can perform more accurate and objective prediction on the occluded vessel segment and / or the narrowed vessel segment, and improve the success rate of interventional therapy.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular to a method for predicting the direction of coronary vessels, a method and a device for training a prediction model. Background technique [0002] Coronary angiography is an effective method for diagnosing coronary artery lesions. This technique can help doctors find the location of narrowed blood vessels, blocked blood vessels or diseased blood vessels. However, for some relatively narrow or severely blocked blood vessel segments, it is difficult for coronary angiography to clearly display them. Generally, doctors predict the direction of relatively narrow or severely blocked blood vessel segments based on experience. The direction of the blood vessel segments predicted based on experience will inevitably deviate greatly from the actual direction of the blood vessel segments, which is very unfavorable to the treatment process of blood vessel dredging. Conte...
