Problems solved by technology

The existing traditional segmentation methods are less robust to the segmentation of sandwich models, and cannot identify true and false lumens alone. Moreover, due to the large size of CTA data, segmentation, segmentation accuracy, and 3D reconstruction efficiency need to be improved urgently.

Abstract

The present application provides a method and device for segmenting a dissecting artery, by acquiring an original CTA image of the aorta to be segmented; preprocessing the original CTA image to obtain a second target CTA image; using the artery segmentation model in the trained segmentation model and the chamber segmentation model, segment the second target CTA image to obtain a first structural model marked with the dissection aorta and branch arteries and a second structural model marked with the true lumen and false lumen on the dissection aorta; The first structural model and the second structural model are used to correct the misclassification of the true cavity and the false cavity on the second structural model. The present application standardizes the original CTA image, and uses the artery segmentation model and the chamber segmentation model to segment the standardized CTA image, which greatly reduces the image data that needs to be processed, effectively improves the efficiency of dissecting artery segmentation, and improves the the segmentation accuracy.

Description

technical field [0001] The present application relates to the technical field of medical image processing, and in particular, to a method and device for segmenting a dissecting artery. Background technique [0002] Aortic dissection (aortic dissection) is a very dangerous aortic disease, which is mainly characterized by the rupture of the intima of the aorta of the patient. , two cavities, the true cavity and the false cavity, are forcibly generated under the impact of blood, which is an extremely dangerous disease and requires timely diagnosis and treatment. Computed tomography angiography (CTA, CT angiography) is the most commonly used method for clinical diagnosis and observation of aortic dissection. Doctors usually analyze the condition based on CT scan tomography, which is not conducive to doctors' acquisition. Accurate 3D morphological features of dissecting aorta, such as determining the size and position of the tear opening, measuring the diameter of the aorta and ...
