Problems solved by technology
[0004] The coronary artery extraction technology based on region growth is based on the region growth of seed points. This technology often leads to incomplete trunk extraction when the coronary angiography is not good enough or the angiography is intermittent, and the region growing technology is generally based on coronary artery enhancement. performed on the basis of results, there is often leakage or insufficient segmentation, resulting in inaccurate coronary edge extraction
The coronary artery extraction technology based on centerline tracking is based on a certain step size and direction. There is a certain interval between the step size and direction, and some small branches may be skipped, resulting in incomplete coronary artery segmentation, and the tracking technology is based on the center line. Based on the implementation, the corresponding contour cannot be extracted very well

Embodiment Construction
[0032] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.
[0033] Computed tomography (CT) generally includes a gantry, a scanning table, and a console for a doctor to operate. A ball tube is arranged on one side of the rack, and a detector is arranged on the side opposite to the ball tube. The console is a computer device that controls the ball tube and the detector to scan, and the computer device is also used to receive the data collected by the detector, process and reconstruct the data, and finally form a CT image. When using CT to scan, the patient lies on the scanning bed, and the scanning bed sends the patient into the ap...

The present application relates to a coronary artery image segmentation method, device, computer equipment and storage medium. The method includes: acquiring the coronary trunk centerline in the initial image; segmenting the initial image to obtain a coronary mask; generating a coronary centerline skeleton according to the coronary trunk centerline and the coronary mask and a distance field; using the pixel points of the coronary artery centerline skeleton as seed points, performing region growth in the distance field to obtain a coronary artery image. Combined with the region growing of the initial image, it can make the edge segmentation more fully and make the extraction of coronary artery contour more accurate. And through the constraints of the distance field, the leakage in the region growing process can be prevented, and the accuracy of coronary artery contour extraction can be further improved.
Description
technical field [0001] The present application relates to the technical field of medical image processing, in particular to a coronary image segmentation method, device, computer equipment and storage medium. Background technique [0002] Cardiovascular disease is a disease with high morbidity and mortality, and has the characteristics of acute onset and strong concealment. Therefore, it is of great clinical significance to realize the diagnosis of heart disease. At present, with the improvement of CT imaging speed and scanning accuracy, CT medical imaging has been widely used in heart examination and disease diagnosis. At the same time, in order to better realize the inspection of cardiovascular diseases, coronary artery segmentation and coronary artery edge extraction are widely used as an auxiliary method. It can accurately extract the edge and contour of the coronary artery, and the extracted coronary artery contour can make it easier for doctors to observe conditions s...
