治疗脑动脉瘤的一种现代技术是在母动脉内插入一个血流分流器。为了产生这种器件的最佳设计，我们考虑了模拟退火优化和晶格玻尔兹曼模拟相结合的方法。在支架效率方面，我们的结果超过了最近文献中使用其他优化方法获得的结果。虽然我们的方法仍然是2D的，但它展示了该方法的潜力。我们给出了一些关于如何调查3D病例的提示。(C) 2012 Elsevier B.V.版权所有
A modern technique to treat cerebral aneurysms is to insert a flow diverter in the parent artery. In order to produce an optimal design of such devices, we consider a methodology combining simulated annealing optimization and lattice Boltzmann simulations. Our results surpass, in terms of stent efficiency, those obtained in the recent literature with an other optimization method. Although our approach is still in 2D, it demonstrates the potential of the method. We give some hint on how the 3D cases can be investigated. (C) 2012 Elsevier B.V. All rights reserved.
