Method and device for repairing coronary artery segmentation fracture

Abstract

A method for repairing segmented and broken coronary arteries and a device for repairing segmented and broken coronary arteries. The method includes: obtaining a predicted output image of a coronary artery segmented body; segmenting and selecting the predicted output image to obtain effective connected bodies and candidate connected bodies. body; perform a connectability analysis on the effective connected body and the candidate connected body; if the analysis determines that the effective connected body and the candidate connected body are connectable, then perform the corresponding connection operation to achieve the prediction output image Split break repair. The present invention utilizes the tree-like growth structure of coronary arteries to select effective connective bodies and candidate connective bodies that may be paired with them, so as to better determine the location and status of coronary artery rupture. Then the determined connectable effective connective bodies and candidate connective bodies are connected to complete the repair, which improves the reliability of the results of coronary angiography.

Description

technical field [0001] The invention relates to the field of medical imaging, in particular to a method and device for repairing coronary artery segmentation and rupture. Background technique [0002] With the continuous development of science and technology, coronary angiography technology has been more and more used in medical diagnosis, and automatic coronary reconstruction has important clinical value and practical significance to the medical industry. The existing 3D coronary angiography technology usually utilizes the combination of coronary artery segmentation technology and image enhancement technology, so that coronary artery images can be presented automatically. [0003] However, because the coronary artery segmentation technique has extremely high requirements on the environment, factors such as noise and vibration will have a great impact on the angiographic results, making the coronary artery and its branches prone to rupture during imaging, especially in the l...

Problems solved by technology

[0003] However, because the coronary artery segmentation technique has extremely high requirements on the environment, factors such as noise and vibration will have a great impact on the angiographic results, making the coronary artery and its branches prone to rupture during imaging, especially in the left anterior descending On branch arteries, the rupture results in little or no image signal in the area and cannot be imaged normally

While some diseases, such as myocardial bridging, are prone to occur in the left anterior descending artery, they are often not detected on imaging because of the rupture of coronary artery division
