人体动脉的计算建模已被广泛用于研究几何形状、血液动力学和血管疾病之间的关系。建模技术的最新发展，使人们有可能进行这样的分析，获得非侵入性的现实几何形状，因此，开辟了可能性，以扩大调查的受试者群体。然而，这是可行的，新的方法，从大量的现实模型中获得的数据比较解剖变异的存在必须developed.In本文中，我们提出了一种自动技术的客观比较的分布的几何和血液动力学的数量在表面上的分叉血管。该方法是基于中心线，并包括强大的分解成其组成分支的表面和映射到模板参数平面上的每个分支。该技术的应用，以现实的数据演示了如何获得类似的结果，在类似的几何形状，允许适当的模型对模型的比较。由于采用了计算和微分几何标准，该方法不依赖于用户定义的参数或用户交互，它相对于分叉几何形状是灵活的，并且很容易扩展到互连血管的更复杂配置。
Computational modeling of human arteries has been broadly employed to investigate the relationships between geometry, hemodynamics and vascular disease. Recent developments in modeling techniques have made it possible to perform such analyses on realistic geometries acquired noninvasively and, thus, have opened up the possibility to extend the investigation to populations of subjects. However, for this to be feasible, novel methods for the comparison of the data obtained from large numbers of realistic models in the presence of anatomic variability must be developed.In this paper, we present an automatic technique for the objective comparison of distributions of geometric and hemodynamic quantities over the surface of bifurcating vessels. The method is based on centerlines and consists of robustly decomposing the surface into its constituent branches and mapping each branch onto a template parametric plane. The application of the technique to realistic data demonstrates how similar results are obtained over similar geometries, allowing for proper model-to-model comparison. Thanks to the computational and differential geometry criteria adopted, the method does not depend on user-defined parameters or user interaction, it is flexible with respect to the bifurcation geometry and it is readily extendible to more complex configurations of interconnecting vessels.
