Problems solved by technology
[0003] At present, the automatic segmentation of coronary arteries is very important for the reconstruction of coronary artery images. Because the vascular segmentation technology has high requirements on the environment, factors such as noise and vibration will have a great impact on the angiography results. However, the existing vascular segmentation technology The accuracy is not high enough, and the segmentation recognition ability for small branches and blood vessel ends is not strong enough, and the coronary arteries imaged in special areas such as small branches and blood vessel ends are easy to connect to some non-coronary blood vessels, resulting in a decrease in the accuracy of the segmentation results

Embodiment Construction
[0071] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.
[0072] The inventor found that the current automatic coronary artery segmentation is very important for the reconstruction of coronary artery images. Because the blood vessel segmentation technology has extremely high requirements on the environment, factors such as noise and vibration will have a great impact on the angiography results. However, the existing vascular The accur...

The invention discloses a coronary artery blood vessel segmentation method. The method comprises the following steps: acquiring a coronary artery blood vessel image to be segmented; inputting the to-be-segmented coronary artery blood vessel image into an integral blood vessel segmentation model to obtain an integral blood vessel segmentation result of the to-be-segmented coronary artery blood vessel image; determining blood vessel branch naming information and blood vessel branch local image blocks of the to-be-segmented coronary artery blood vessel image according to the overall coronary artery segmentation result of the to-be-segmented coronary artery blood vessel image; inputting the overall coronary artery segmentation result, the vessel branch naming information and the vessel branch local image blocks into a local vessel segmentation model to obtain a local vessel segmentation result of the coronary artery vessel image to be segmented; and obtaining a blood vessel segmentation result of the coronary artery blood vessel image to be segmented according to the overall blood vessel segmentation result and the local blood vessel segmentation result. The accuracy of blood vessel segmentation can be improved, so that the accuracy of the blood vessel segmentation result of the coronary artery blood vessel image to be segmented is improved.
Description
technical field [0001] The present application relates to the field of medical data analysis, in particular to a coronary artery segmentation method and device. Background technique [0002] To maintain the normal life activities of various tissues and organs of the human body, the heart needs to keep beating to ensure blood circulation. The aorta is the largest artery, which originates from the heart and is responsible for the blood supply of the whole body. As a muscular power organ that pumps blood, the heart itself also needs sufficient nutrition and energy. Coronary arteries are blood vessels dedicated to nourishing the heart. They originate from the root of the aorta and divide into left and right branches, running on the surface of the heart. Both are sent from the heart to supply oxygen and nutrients to the organs. [0003] At present, the automatic segmentation of coronary arteries is very important for the reconstruction of coronary artery images. Because the vas...
