Embodiment Construction

[0020] The invention automatically detects blood vessel stenosis from coronary angiography images, marks the location of the stenosis, and provides accurate coronary stenosis information for subsequent diagnosis of coronary heart disease. like figure 1 As shown, the blood vessel stenosis detection method in this coronary X-ray sequence angiography comprises the following steps:

[0021] (1) Obtain the sequence image information of the XRA image;

[0022] (2) Coronary artery stenosis detection: Combining the information of the front and rear frames in the sequence image to realize the detection of coronary artery stenosis on a single frame image, and then perform deep sequential feature fusion on the image detection results of multiple consecutive frames to obtain each frame of this continuous multiple frame A more accurate stenosis detection result, which is used as the initial sequence stenosis detection result;

[0023] (3) The initial sequence narrow detection results are...

Abstract

The invention discloses a method and a device for detecting vascular stenosis in coronary artery X-ray sequential radiography, which can be used for effectively detecting a suspected stenosis area ona blood vessel in a sequential image to obtain an accurate coronary artery stenosis detection result, and can be used for really helping doctors to carry out effective and quick disease diagnosis. Themethod comprises the following steps: (1) acquiring sequence image information of an XRA image; (2) coronary artery stenosis detection: combining front and back frame information in the sequence image to realize coronary artery stenosis section detection on the single-frame image, performing depth sequence feature fusion on continuous multi-frame image detection results to obtain more accurate stenosis detection results on each frame of the continuous multi-frame image, and taking the detection results as initial sequence stenosis detection results; and (3) processing the initial sequence narrow detection result, and obtaining an accurate detection result by removing repeated detection boxes in the frame and reserving the detection box with high similarity in the sequence.

Description

technical field [0001] The invention relates to the technical field of medical image processing, in particular to a method for detecting vascular stenosis in coronary X-ray sequence angiography, and also to a device for detecting vascular stenosis in coronary X-ray sequence radiography. Background technique [0002] Considering that most existing detection methods for coronary artery stenosis are aimed at three-dimensional CT angiography (Computed Tomography Angiography, CTA), or single-frame two-dimensional angiography images, these methods cannot well realize two-dimensional coronary artery X-ray sequence angiography images ( Detection of coronary artery stenosis in X-Ray Angiography (XRA) images, so the present invention proposes a method that can automatically detect vascular stenosis and mark its position from coronary artery XRA sequence images. Accurate detection of coronary artery stenosis on serial XRA images can assist doctors to complete disease diagnosis efficien...
