Patient specific modelling of the blood flow through the human aorta is performed using computational fluid dynamics (CFD) and magnetic resonance imaging (MRI). Velocity patterns are compared between computer simulations and measurements. The workflow includes several steps: MRI measurement to obtain both geometry and velocity, an automatic levelset segmentation followed by meshing of the geometrical model and CFD setup to perform the simulations follwed by the actual simulations. The computational results agree well with the measured data.
使用计算流体动力学(CFD)和磁共振成像(MRI)对通过人体主动脉的血流进行患者特异性建模。将计算机模拟结果与测量结果进行速度模式比较。该工作流程包括几个步骤:通过MRI测量以获取几何形状和速度,进行自动水平集分割,随后对几何模型进行网格划分并设置CFD以执行模拟,最后进行实际模拟。计算结果与测量数据吻合良好。
