COMPUTATION METHOD OF RELATIVE CARDIOVASCULAR PRESSURE |
| 摘要 |
The present invention provides a method for the determination of relative pressure fields from flow-sensitive data, the method comprising: applying a finite element discretisation to the Pressure Poisson Equation (PPE):;b=f+μΔu-ρ(∂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 p and μ 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: Δp=∇·b. |

1. A method for the determination of relative pressure fields from flow-sensitive data, said method comprising: applying a finite element discretisation to the Pressure Poisson Equation (PPE):b=f+μΔu-ρ(∂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 ρ and μ 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:
Δp=∇·b. |
