Abstract
There is described a method for calculating a patient-specific hemodynamic parameter. The method comprises measuring at least one pressure measurement in an artery using an intravascular pressure measurement device, and taking at least one medical image of the artery from a medical imaging instrument, the at least one medical image of the artery being synchronous with the at least one pressure measurement. Both the pressure measurement and the medical image are fed to a computing system to calculate a flow from the at least one medical image, to calculate parameters of the artery from at least two artery pressure drops and corresponding flow components, and based on the flow and the parameters of the artery, to calculate a patient-specific hemodynamic parameter or a plurality thereof.
