preparation example Construction

[0132] Such as Figure 10 As shown, the application provides a method for synthesizing three-dimensional blood vessels, including:

[0133] The above-mentioned method S100-S600 for accurately obtaining the vascular stenosis lesion interval;

[0134] S700, acquiring the angle value of the body position of each two-dimensional coronary angiography image;

[0135] S800. According to the angle value of the body position, project the two-dimensional coronary angiography images of at least two body positions from which the centerline and outline of the blood vessel are extracted on a three-dimensional plane to synthesize the three-dimensional blood vessel.

[0136] Such as Figure 10 As shown, an embodiment of the present application further includes: S900, acquiring the centerline of the three-dimensional blood vessel, repeating the above-mentioned method for accurately acquiring the stenosis lesion interval of the blood vessel, and reacquiring the stenosis lesion interval and th...

Abstract

The invention provides a method, a device and a system for acquiring a vascular stenosis lesion interval and performing three-dimensional synthesis. The method for accurately acquiring the stenosis lesion interval of the blood vessel comprises the following steps: reading coronary artery two-dimensional contrast image groups of at least two body positions; extracting a vascular skeleton; obtainingan interested blood vessel segment; extracting a center line and a contour line of the interested blood vessel section according to the blood vessel skeleton; obtaining geometric structure information of the blood vessel section; and obtaining a stenosis lesion interval and a stenosis point of the interested blood vessel segment. Coronary artery two-dimensional contrast image groups of at least two body positions are read; a vascular skeleton, a center line and a contour line are extracted; the stenosis lesion interval is obtained according to the geometric structure information, a doctor does not need to judge stenosis manually according to experience, and the obtaining mode is more accurate.

Description

technical field [0001] The invention relates to the technical field of coronary artery medicine, in particular to a synthesis method, device, coronary artery analysis system and computer storage medium for accurately obtaining vascular stenosis lesion intervals and three-dimensional blood vessels. Background technique [0002] According to the statistics of the World Health Organization, cardiovascular disease has become the "number one killer" of human health. In recent years, the use of hemodynamics to analyze the physiological and pathological behavior of cardiovascular diseases has also become a very important means for the diagnosis of cardiovascular diseases. [0003] Among many coronary artery physiological function evaluation techniques, fractional flow reserve (FFR) is currently recognized as the most accurate functional evaluation index. Moreover, FFR has become the gold standard for the clinical diagnosis of coronary heart disease, and is recommended by the Europ...
