Abstract

The invention provides a coronary vessel extraction method and device based on multi-view model fusion, and the method comprises the steps: inputting an original coronary vessel CTA image, obtaining aheart segmentation result, carrying out the cutting of the original CTA image according to the size of a heart, and obtaining a cut coronary vessel CTA image; training a coronary vessel segmentationnetwork by using the multi-view image, wherein the coronary vessel segmentation network comprises a first coronary vessel segmentation model, a second coronary vessel segmentation model and a third coronary vessel segmentation model; segmenting the cropped coronary artery CTA image by using a first coronary artery blood vessel segmentation model to obtain a first segmentation result, segmenting the cropped coronary artery CTA image by using a second coronary artery blood vessel segmentation model to obtain a second segmentation result, and segmenting the cropped coronary artery CTA image by using a third coronary artery blood vessel segmentation model to obtain a third segmentation result; and combining the first segmentation result, the second segmentation result and the third segmentation result to obtain a final coronary vessel segmentation result.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for extracting coronary vessels based on multi-view model fusion. Background technique [0002] Angiography technology has been widely used in clinical diagnosis and treatment. The segmentation algorithm can realize automatic vascular reconstruction (such as head and neck vessels, coronary arteries, etc.), which greatly improves the operating efficiency of the hospital while reducing the work pressure of technicians. . In actual scenarios, some external factors (such as artifacts, noise, shooting technology, etc.) will affect the quality of vascular imaging. It is difficult to judge the trend of some blood vessels when analyzing CT images from a single view such as axial view, so it is necessary to combine Learning from multiple views improves segmentation accuracy. [0003] However, the scanning field of view of different coronary images is different, and...
