Calculation of boundary conditions for virtual FFR and IFR calculations based on myocardial dye characteristics

摘要

An apparatus for evaluating a patient's vascular system is provided. The apparatus derives a physiologic model of the vascular system, including the geometry model of interest vessels and a fluid dynamic model, and a dynamic scale indicative of the dynamics of contrast agents passing through the vascular system from multiple diagnostic images to adjust the at least one boundary condition of the fluid dynamic model Analyze at least one dynamic scale as a function of time.
