计算流体动力学（CFD）和磁共振成像（MRI）的结合提供了一种有前途的工具，可以预测特定受试者心血管模型中的血流模式。模型的几何形状对模拟精度的影响是公认的。本文讨论了不同的边界条件对受试者特定的模拟左心室（LV）流量的影响。提出了一种新的混合方法，用于在二尖瓣平面中规定有效的流入边界条件。详细的定量结果突出了这种方法的优点和潜在的缺陷。
The combination of computational fluid dynamics (CFD) and magnetic resonance imaging (MRI) offers a promising tool that enables the prediction of blood flow patterns in subject-specific cardiovascular models. The influence of the model geometry on the accuracy of the simulation is well recognized. This paper addresses the impact of different boundary conditions on subject-specific simulations of left ventricular (LV) flow. A novel hybrid method for prescribing effective inflow boundary conditions in the mitral valve plane has been developed. The detailed quantitative results highlight the strengths as well as the potential pitfalls of the approach.
