Method of modeling blood vessels and blood flow in these blood vessels models

摘要

The method of blood vessel modelling and blood flow in these blood vessel models shall be reported. In this way, based on the results of medical imaging, a personalised three-dimensional blood vessel model (1) is constructed electronically,and then also a reference three-dimensional blood vessel model (6) is constructed by computer,which reflects the condition of healthy blood vessels, free of disease (2) seen in medical imaging. In both blood vessel models (1, 6), a numerical simulation of blood flow is performed for the same physical and coastal conditions, establishing and regulating blood flow conditions at the inlet to the blood vessel model (1, 6) from laminar to turbulent flow. At the same time, blood flow energy is measured at the inlet and all outlets of these model blood vessels (1, 6),and then compare the flow energy obtained between the personalised blood vessel model (1),a reference blood vessel model (6).
