Method for identifying and predicting radiotherapy dose of heart electrocardio conduction system through image segmentation

The invention relates to a method for identifying and predicting the radiotherapy dose of a heart electrocardio conduction system through image segmentation, which comprises the following steps of: S1, segmenting a CT (Computed Tomography) image through logical operation of an algorithm system in a radiotherapy planning system to generate a seven-layer elliptical structure, simulating a sinoatrial node structure and predicting the radiotherapy dose of the sinoatrial node; s2, segmenting the CT image through logical operation of an algorithm system in a radiotherapy planning system to generate a seven-layer elliptical structure, simulating an atrioventricular junction structure and predicting the radiotherapy dose of the atrioventricular junction; s3, segmenting the CT image through logical operation of an algorithm system to generate a three-layer cylindrical structure, simulating a His beam structure and predicting the radiotherapy dose of the His beam; and S4, calculating doses of sinus nodes, atrioventricu
