Detailed ways

In order to make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only some, but not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

Various embodiments of the present invention will be disclosed in the drawings below, and for the sake of clarity, many practical details will be described together in the following description. It should be understood, however, that these practical details should not be used to limit the invention. That is, in some embodiments of the invention, these practical details are unnecessary.

A device for analyzing coronary arteries in the prior art adopts a 2D angiography image, and then calculates a blood vessel evaluation parameter according to the 2D image. The contour of the blood vessel obtained from the 2D angiography image is two-dimensional, and a certain shooting angle may block the stenotic area. Therefore, the obtained vascular stenosis area is inaccurate, which leads to the problem that the size of the selected stent is too large or too small, and it may not even be necessary to place a stent, and the vascular contour obtained from the 2D angiography image leads to the problem of excessive stent placement. The image processing device and the blood vessel evaluation parameter calculation device in the prior art are separated, resulting in a large machine occupation space, low accuracy in selecting the size of the blood vessel stent, low integration, and cumbersome movement.

In order to solve the above problems, the present application provides a coronary artery analysis system and an operation method thereof. An integrated computer is provided, and the image processing device and the blood vessel evaluation parameter calculation device are set as an integrated system, which has a high degree of integration, a small occupied space, and Through 2D angiography images, three-dimensional modeling of blood vessels is carried out, which is convenient for viewing the three-dimensional shape of blood vessels, and can more accurately display the stenotic area of blood vessels, thereby improving the accuracy of vascular stent size selection and facilitating movement.
