AI Technical Summary

Technical Problem

During the three-dimensional reconstruction of the lung, due to the absence of contrast agents for the chest scanning CT, the contrast between the arteries and veins is not obvious enough, making it difficult to distinguish or clearly display these vascular structures in the two-dimensional slice images, increasing the number of images from the chest scanning CT. The difficulty of identifying tiny blood vessel structures may even errors during the three-dimensional reconstruction process, affecting the accuracy and reliability of the reconstruction image.

Method used

The lung image is determined by performing lung segmentation on the chest image; the lung image is segmented into arteries and veins in the hilus and arteries and veins in the lung tissue, combined with the mask image, and merged to obtain the arteriovenous images in the chest image to achieve Precise segmentation of pulmonary blood vessels.

Benefits of technology

It achieves precise segmentation of pulmonary arteries and veins in plain chest images, and can effectively capture the details of the vascular structure, especially without using contrast agents, which improves the visualization of pulmonary blood vessels in chest images. The accuracy and reliability of three-dimensional reconstructed images are improved.

Abstract

The present disclosure provides a pulmonary blood vessel segmentation method, device, electronic device and storage medium. The method includes: performing lung segmentation on a chest image to determine a lung image in the chest image; performing intra-hilar artery and vein segmentation on the lung image to determine an intra-hilar artery and vein segmentation mask image in the lung image; performing intra-pulmonary tissue artery and vein segmentation on the lung image, combining the intra-hilar artery and vein segmentation mask image to determine a pulmonary tissue artery and vein segmentation mask image in the lung image; merging the intra-hilar artery and vein segmentation mask image with the pulmonary tissue artery and vein segmentation mask image to obtain an artery and vein image in the chest image, achieving accurate segmentation of pulmonary arteries and veins in a plain scan chest image, being able to effectively capture the details of the vascular structure, especially in the absence of a contrast agent, improving the visualization effect of pulmonary blood vessels in the chest image.
