Method for measuring vascular diameter in coronary angiography image based on depth learning

The invention discloses a method for measuring the vascular diameter in a coronary angiography image based on depth learning. The method for measuring the vascular diameter in a coronary angiography image based on depth learning comprises the following steps: a DSA image processing module converts real-time acquired DSA image data into a data stream which can be processed by a subsequent module, and stores the data stream in a memory and sends the data stream to a depth network segmentation module. The depth network segmentation module segments the acquired DSA image data to distinguish the blood vessel pixel from the background pixel. The centerline extracting module extracts the blood vessel centerline from the blood vessel pixel image. The diameter calculation module calculates the measured diameter, the reference diameter and the stenosis rate of the blood vessel based on the segmented image and the blood vessel centerline. Compared with the PVA method, the invention has more objective results and avoids the differences between different doctors and different hospitals due to different interpretation methods. This method does not need manual intervention and is easy to operate.It can be used by doctors in coronary angiography and can provide objective reference for doctors to determine the degree of coronary stenosis.
