Method for extracting cardiovascular vessels from CTA images, device, apparatus and storage medium

Abstract

The invention belongs to the medical image processing technical field and provides a method for extracting cardiovascular vessels from CTA (computed tomography angiography) images, a device for extracting cardiovascular vessels from CTA images, an apparatus for extracting cardiovascular vessels from CTA images and a storage medium. The method includes the following steps that: etching operation and expansion operation are sequentially performed on image data by using preset structural elements, so that a structural template is obtained; layer-by-layer transformation is performed on the sectional images of the structural template, so that a first ascending aorta structure in the structural template can be obtained, aorta center coordinates and an aorta radius are obtained from the last sectional image layer of the structural template; and a binary sphere structure is built according to the aorta center coordinates and the aorta radius, and the first ascending aorta structure is combined with the structural template and the binary sphere structure, so that a second ascending aorta structure can be obtained through combination. With the method, device, apparatus and storage medium of the invention adopted, ascending aortas and the shapes of aortic sinuses at the roots of the ascending aortas can be extracted, and therefore, the structures and shapes of the aortas can be accurately visualized, and the solving level and capability of medical image research on clinical problems can be improved.

Description

technical field

[0001] The invention belongs to the technical field of medical image processing, and in particular relates to a method, device, equipment and storage medium for extracting cardiovascular from CTA images. Background technique

[0002] Cardiovascular extraction, as a means of image preprocessing, is of great significance for the visualization of clinical diagnosis, interventional surgery planning and interventional treatment process. It is to extract the ascending segment of cardiac aorta and enhance coronary vessels from three-dimensional medical angiography images. Since the CT (Computed Tomography, computerized tomography) coronary angiography (CTA) image of the heart presents complex tissue structure and background noise, the contrast of blood vessels in the heart is very small, and the contrast of the external pulmonary artery is extremely high, which increases the risk from cardiac CTA. The difficulty in extracting the aorta and coronary vessels in the im...
