[0039] Example: Reference Figure 1 to 3 As shown, a method for extracting the centerline of a coronary artery vessel includes the following steps:
[0040] Step S1: Input the data of coronary artery tree and aorta;
[0041] Step S2: According to the coronary tree and aorta data in step S1, the intersection part is obtained from the overlapping part of the data, and the centroid M is obtained. The three-dimensional coordinate formula of the centroid M is:
[0042]
[0043] Where m i Is the coordinate point (x i , Y i ,z i ) Gray value;
[0044] Then, with the center of mass M as the starting point, the data of the coronary artery tree is gradually traversed to the end of each branch vessel by using the encroachment method to obtain the end points of all branch vessels. The specific method for obtaining the end points of all branch vessels is as follows:
[0045] Step A: Set the list List to represent the collection of the end points of all branch vessels. ListA represents the center an...
