Embodiment 1

[0006] Embodiment 1: Firstly, the first multi-dimensional coronary artery matrix depth information image is processed by the first calculation unit, and the blood vessel part Kt in the first stenosis area in the first multi-dimensional coronary artery matrix depth information image is calculated by the first calculation unit Process to obtain the first image A, and perform the first image instance segmentation Go on the first image A to obtain the segmented second coronary artery image, and use the first mask branch Qi to divide the coronary artery in the image instance The contour of the blood vessel part Kt in the first stenotic area in the stenosis is identified, so as to establish the model St of the first image instance segmentation Go; the model S of the first image instance segmentation Go is passed through the mask branch of the mask-based regional convolutional neural network After completing the image instance segmentation task, start the target detection task, and ca...

Abstract

The invention relates to a method for diagnosing and positioning coronary artery stenosis by using a computer, which comprises the following steps of: processing a first multi-dimensional coronary artery matrix depth information image through calculation, and calculating and processing a first stenosis area blood vessel part Kt in the first multi-dimensional coronary artery matrix depth information image through a first calculation unit to obtain a first image A; and performing first image instance segmentation Go on the first image A to obtain a segmented second coronary artery blood vessel image.

Description

technical field [0001] The invention relates to a medical auxiliary diagnosis method, which is a method for diagnosing and positioning coronary artery stenosis by using a computer, and belongs to the field of new medical engineering. Background technique [0002] By studying the algorithm in the field of instance segmentation, the instance segmentation of the blood vessel part in the coronary artery stenosis area is carried out. When diagnosing coronary artery stenosis, doctors not only need to observe the location of the stenosis, but usually also need to judge the degree of vascular stenosis to judge the patient's condition, decide on the treatment plan, and determine whether coronary artery stent surgery is necessary. Therefore, it is necessary to draw the outline of the stenosis area to assist the doctor in making a diagnosis or to give the degree of stenosis by the machine. At present, most of the work in the field of blood vessel segmentation is in the field of semant...
