Embodiment 1
[0063] In order to further understand the present invention, the present invention will be further elaborated and illustrated below in conjunction with the examples. figure 1 It is a flow chart of the method of the present invention, combined with image 3 In a specific embodiment, the method can be summarized as: acquiring image data of the lumen of the vessel of interest from traditional coronary angiography data, establishing a geometric model of the vessel segment and obtaining geometric parameters, Evaluate the maximum blood flow velocity V of the vessel segment under the condition of fully expanded myocardial microcirculation, that is, the state of maximum hyperemia, by using the resting-state conventional angiographic data without sufficient expansion of myocardial microcirculation max and coronary blood flow Q max , to solve the pressure difference ΔP corresponding to the maximum blood flow velocity max , coronary artery proximal endpoint pressure P a and the distal...
Embodiment 2
[0102] In another specific embodiment, the method of the present invention is used to analyze the microcirculation resistance of a specific coronary vessel, and a specific example of the left anterior descending coronary artery is used to illustrate the specific implementation of the present invention. Specifically, this method can be implemented through the following steps:
[0103] (1) Carry out traditional X-ray contrast imaging process. For example, it can be conventional image data taken by combining with a contrast agent;
[0104] (2) Select the left anterior descending coronary artery of the heart as the vessel of interest, and determine the starting point and the ending point of the blood vessel; that is, the starting point and the ending point of a section of the blood vessel to be focused on;
[0105] (3) establish the geometric model of left anterior descending coronary artery, described geometric model comprises actual vessel lumen geometric model, ideal vessel lu...
Embodiment 3
[0114] In yet another specific embodiment, such as figure 2 As shown, the present invention also provides a system for rapidly calculating microcirculation resistance based on imaging data, the system comprising:
[0115] An image acquisition module, configured to receive image data of the lumen of the vessel of interest;
[0116] The geometric model building module is used to establish the actual vessel lumen model and the ideal vessel lumen model of the vessel of interest, and deliver the results to the geometric parameter acquisition module;
[0117] The geometric parameter acquisition module acquires the geometric parameters of the vessel segment of interest, including the area or diameter of the proximal cross-section of the vessel segment, the area or diameter of the distal cross-section of the vessel segment, the position of the vessel segment at the proximal end point and the distal end point The cross-sectional area or diameter of the lesion, lesion length, stenosis...
