Lung artery and vein extraction method and device based on CT image and electronic equipment

Abstract

The invention provides a lung artery and vein extraction method based on a CT image. The method comprises the following steps: acquiring a lung CT image to be segmented; establishing N targets to be segmented on the lung CT image; setting a preset target threshold value and a plurality of first seed points for each target; according to the first seed point and the target threshold value, synchronous growth operation is carried out to extract lung trunk blood vessels; extracting intrapulmonary blood vessels from the lung CT image; and connecting the lung trunk blood vessel with the intra-pulmonary blood vessel. The invention further provides a lung artery and vein extraction device based on the CT image and electronic equipment. Therefore, the lung artery and vein blood vessels can be segmented more accurately, and more accurate diagnosis and treatment information can be provided for doctors.

Description

Technical field [0001] The present invention relates to the field of medical image processing, and more particularly to a pulmonary vein extraction method, apparatus, and electronic device based on a CT image. Background technique [0002] With the development of medical imaging technology, the image of CT (Computed Tomography, computer fault imaging) has become an important basis for diagnosing the disease. The lung contains a large number of vascular, pulmonary artery and pulmonary veins. The vasod vessel distribution in the pulmonary CT image is an important basis for diagnosing the disease and formulating surgical programs. Correctly dividing pulmonary blood vessels, providing a more accurate diagnosis and treatment information to the doctor, significant. [0003] Conventional methods typically need to obtain a CT image of two phase phases of arteries and venous periods, which are used to extract pulmonary artery and pulmonary veins. Although this method can better extract pu...

AI Technical Summary

Problems solved by technology

Secondly, the movement of the lungs will cause the two-phase images to be slightly misaligned, so the pulmonary arteries and veins extracted under the two-phase images will somewhat have a position mismatch

Moreover, due to the problem of scanning quality, many images show that both pulmonary arteries and veins are developed or lack of development. In this kind of images, arteriovenous CT values ​​are similar, and the borders are weak. Traditional methods are prone to weak borders, arteriovenous The connection overflows, making it difficult to accurately extract the pulmonary arteries and veins in the same phase of the image

[0004] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve
