Problems solved by technology

The lack of explicit modeling of the relationship between blood vessels has the following defects: First, the legitimacy of naming is difficult to guarantee. For each segment of the vessel is predicted separately, it may happen that a segment of the vessel originating from the LAD is named as The case of OM
Second, such methods independently predict each vessel segment, without explicitly modeling the relationship between each vessel segment, so it is impossible to achieve interactive modification that supports the linkage adjustment of vessel names

Abstract

The invention discloses an automatic naming method and device for cardiac coronary vessels, and the method comprises the following steps: constructing a neural random grammar model, and training the neural random grammar model; acquiring a coronary blood vessel image, and extracting a coronary blood vessel center line; identifying the center line of the coronary blood vessel, extracting features based on point cloud, and predicting features of the blood vessel segment; extracting the features of the blood vessel segment by using the prediction results of the features based on the point cloud and the features of the blood vessel segment; and inputting the features of the blood vessel segments into the constructed neural random grammar model to obtain a blood vessel name. According to the method, extremely tedious and error-prone rules do not need to be formulated, and interactive modification of blood vessel name linkage adjustment can be achieved.
