  • Computation method of relative cardiovascular pressure
    Patent number: 9986966
    Abstract: The present invention provides a method for the determination of relative pressure fields from flow-sensitive data, the method comprising: applying a finite element discretization to the Pressure Poisson Equation (PPE): b = f + ?? ? ? u - ? ? ( ? u ? t + ( ( u - w ) · ? ) ? u ) where vecter b is a function of a given blood velocity data, u represents the velocity, w the reference velocity, t the time, f a volume force, p the pressure and ? and ? the fluid density and viscosity, respectively, and wherein the PPE is now defined as the divergence of the above equation and gives a higher order derivative of the pressure field p: ?p=?·b.
