Problems solved by technology

However, individuals with different coronary arteries have various variations. Some people have only a dozen blood vessels, while others have dozens or even hundreds of blood vessels. Therefore, the division and identification of coronary arteries has always been It is a very time-consuming and labor-intensive job

Embodiment

[0056] Such as figure 1 As shown, the cardiac coronary artery automatic segmentation naming method includes:

[0057] S1. Extract the blood vessel centerline of the 3D image of the coronary artery of the heart, and define the three-dimensional coordinates of each point in the blood vessel centerline;

[0058] S2, identifying the left coronary artery and the right coronary artery from the coronary arteries of the heart;

[0059] S3. Identify RCA, R-PDA and R-PLB from the identified right coronary artery;

[0060] S4. Identify LM, LAD and LCX from the identified left coronary artery;

[0061] S5. Identify OM1, OM2 and OM3 from the identified LCX;

[0062] S6. Identify D1, D2 and D3 from the identified LAD;

[0063] S7. Identify RI from the identified LAD and LCX.

[0064] Such as figure 2 As shown, the blood vessel centerline of the coronary artery 3D image is generated as follows:

[0065] S11. Obtain the original CT image of the patient's heart coronary vessels;

Abstract

The invention discloses an automatic segmentation and naming method of cardiac coronary artery vessels. The method comprises the steps of: S1, extracting vessel center lines of a cardiac coronary artery 3D image, and defining three-dimensional coordinates of each point in the vessel center lines; S2, identifying a left coronary artery and a right coronary artery from the cardiac coronary artery vessels; S3, identifying RCA, R-PDA and R-PLB from the identified right coronary artery; S4, identifying LM, LAD and LCX from the identified left coronary artery; S5, identifying OM1, OM2 and OM3 from the identified LCX; S6, identifying D1, D2 and D3 from the identified LAD; and S7, identifying RI from the identified LAD and LCX. According to the method, an identification algorithm in each step is improved on the basis of center line data of the cardiac coronary artery vessels, and needed target blood vessels can be accurately and automatically identified from tens to hundreds of vessels and accurately named.

Description

technical field [0001] The invention relates to the field of heart coronary blood vessel image processing, in particular to a method for automatically segmenting and naming heart coronary blood vessels. Background technique [0002] For the diagnosis of heart-related diseases, blood vessel identification and naming of the left and right coronary arteries of the heart is a crucial step. However, individuals with different coronary arteries have various variations. Some people have only a dozen blood vessels, while others have dozens or even hundreds of blood vessels. Therefore, the division and identification of coronary arteries has always been It is a very time-consuming and labor-intensive job. Contents of the invention [0003] The purpose of the present invention is to provide a method for automatically segmenting and naming cardiac coronary vessels based on central line data of cardiac coronary vessels. [0004] To achieve the above object, the present invention ado...
