Summary: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
