Abstract

The invention belongs to image analysis, and in particular relates to an aneurysm image analysis system, method and device based on dual-flow boundary perception, aiming to solve the problem that the existing image analysis technology cannot accurately analyze the image of aneurysm based on the developed image. The present invention includes: acquiring a DSA image of a region containing an aortic aneurysm as an image to be detected, based on the image to be detected, generating an aortic aneurysm boundary feature image and an aortic aneurysm image mask through a trained two-stream boundary perception network, based on The aortic aneurysm image mask and the aortic aneurysm boundary feature are combined with the DSA image to obtain morphological information of the aortic aneurysm image. The invention improves the accuracy of aneurysm images and solves the problem of blurred boundaries of aneurysm images in the prior art by inputting the extracted features into a dual-stream boundary perception network, simultaneously extracting boundary features and mask images and merging them. Accurate aneurysm morphology analysis.

Description

technical field [0001] The invention belongs to image analysis, and in particular relates to an aneurysm image analysis system, method and device based on dual-flow boundary perception. Background technique [0002] Abdominal aortic aneurysm (AAA) is caused by abnormal dilation of the aorta. Because the AAA does not show typical symptoms until it ruptures, it usually results in an 85% to 90% case-fatality rate. The diameter of a normal aorta is 20 mm, and an aneurysm is considered to exist when the diameter of an aorta is more than 50% wider than normal. [0003] Endovascular aneurysm repair (EVAR) surgery is currently the treatment for most AAA patients. Compared with open repair methods, EVAR surgery has many important advantages, including less damage, more stability, lower perioperative mortality of patients, and lower possibility of postoperative complications. EVAR surgery is performed to remove the aneurysm from the circulation by placing an aortic stent. However,...
