血管结构的计算血流和血管壁力学模拟正在成为针对特定患者的手术计划和干预的重要研究工具。针对特定患者的模拟的建模过程中的一个重要步骤是基于分段几何形状创建计算网格。大多数已知的解决方案要么需要大量的手动处理，要么导致分割的对象与实际计算域之间存在显着差异。我们开发了一系列算法，可实现与可变形模型和 3D 网格生成密切相关的图像分割实现。由此产生的处理链非常稳健，可以实现血管结构的精确几何表示以及高质量的计算网格。该算法链已在各种形状上进行了测试。我们的网格生成应用程序与其他五个可用的网格划分应用程序的基准比较清楚地表明，新方法在大多数情况下优于现有方法。
Computational blood flow and vessel wall mechanics simulations for vascular structures are becoming an important research tool for patient-specific surgical planning and intervention. An important step in the modelling process for patient-specific simulations is the creation of the computational mesh based on the segmented geometry. Most known solutions either require a large amount of manual processing or lead to a substantial difference between the segmented object and the actual computational domain. We have developed a chain of algorithms that lead to a closely related implementation of image segmentation with deformable models and 3D mesh generation. The resulting processing chain is very robust and leads both to an accurate geometrical representation of the vascular structure as well as high quality computational meshes. The chain of algorithms has been tested on a wide variety of shapes. A benchmark comparison of our mesh generation application with five other available meshing applications clearly indicates that the new approach outperforms the existing methods in the majority of cases.
