[0109]
[0110] Coronary artery automatic segmentation and anatomical labeling method based on spherical space division, the implementation flow chart of this method is as follows figure 1 , the specific implementation process is as follows:
[0111] Step 1. Image preprocessing: obtain coronary artery segmentation images and centerlines;
[0112] Step 2, pruning operation;
[0113] Step 3, definition of sphere center and sphere space;
[0114] Step 4, division rules of left and right coronary arteries;
[0115] Step 5, left coronary artery anatomical naming algorithm;
[0116] Step 6, right coronary artery anatomical naming algorithm.
[0117] The step 1 obtains the coronary artery segmentation...
