FFR rapid calculation system model based on zero-dimensional hemodynamic model

The invention discloses an FFR rapid calculation system model based on a zero-dimensional hemodynamic model, which belongs to the field of hemodynamic numerical simulation. The system comprises a personalized zero-dimensional hemodynamic construction model, a stenosis resistance theoretical calculation model, a stenosis resistance determination model and an FFR model. In a resting state, the zero-dimensional model is personalized through coronary artery post-load and other model parameters including the heart. In a hyperemia state, the stenosis resistance output by the resistance model is taken as the input of the zero-dimensional model to influence the flow distribution of each branch of the coronary artery of the zero-dimensional model, and the stenosis branch flow output by the zero-dimensional model is taken as the input of the resistance model to recalculate the stenosis resistance. The two models are repeatedly iterated until the flow is matched with the resistance, the stenosisresistance is finally det
