Problems solved by technology

[0004] Among the existing technologies, the calculation methods of hemodynamic parameters currently used generally have the problems of large errors and poor versatility. The main reason is that there is a lack of a complete and widely applicable vascular modeling system, resulting in relatively rough vascular models. , and usually can only be modeled for specific blood vessels, poor versatility

Abstract

The invention relates to a hemodynamic parameter calculation method and system and an electronic device. The method comprises the following steps of A carrying out preliminary blood vessel segmentation on an original medical image; B extracting a blood vessel center line according to the preliminary blood vessel segmentation result; C calculating a blood vessel contour on a vertical plane along the blood vessel center line; D generating a three-dimensional model of the blood vessel at the intermediate difference value of the blood vessel contour; E gridding the three-dimensional model of the blood vessel to obtain model grid information; F quantifying fluid simulation parameters; and G solving a fluid mechanics equation according to the model grid information and the fluid simulation parameters to obtain the hemodynamic parameters. Compared with the prior art, the application has a complete blood vessel modeling system and a parameter calculation system, by which errors can be greatlyreduced compared with the prior art, and the precision and universality of blood vessel dynamics parameter calculation are integrally improved.

Description

technical field [0001] The present application belongs to the technical field of hemodynamics, and in particular relates to a calculation method, system and electronic equipment of hemodynamic parameters. Background technique [0002] Medical image analysis is one of the important means to help doctors diagnose patients' conditions and is widely used in clinical practice. Medical image analysis refers to the process of extracting parameter information from medical images by using human subjectivity or analysis techniques such as image processing. [0003] Calculation of hemodynamic parameters of blood vessels is a common method in medical image analysis, which requires the calculation of blood flow parameters such as flow velocity, pressure, and wall shear force of blood vessels, so as to greatly facilitate doctors' diagnosis of patients' conditions. [0004] Among the existing technologies, the calculation methods of hemodynamic parameters currently used generally have the...
