提出了一种用于模拟血管内介入的体外患者特定血管模型。建议的血管模型再现三维血管管腔结构，使用CT/MRI信息与13妈妈的分辨率，它也再现动脉组织的物理特性（弹性模量和摩擦系数）。此外，在本文中，我们提出了一种新的方法来评估血管的应力，这是施加在外科手术。该方法允许在手术模拟期间实时定量评估三维应力条件。最后，我们构建了一个全面的手术模拟系统，该系统再现了整个人体主动脉结构（内径超过1 mm），再现了患者特定的脉动血流，允许以与实际血管内介入几乎相同的方式和环境评估手术操作对主动脉结构施加的应力。因此，所提出的模型，评估方法和结果系统提供了一个非常有价值的平台，用于评估由开发人员和研究人员开发的手术机器人和器械的性能，以及手术过程
An in vitro patient-specific vascular model, for simulating endovascular intervention is presented. Proposed vascular model reproduces the 3-dimensional vessel lumen structure using CT/MRI information with 13 mum resolution, and it also reproduce the physical characteristics of arterial tissue (elastic modulus and friction coefficient). Furthermore, in this paper, we propose a novel method to evaluate the stress on vasculature which is applied by surgical operations. This method allows quantitatively evaluating 3-dimensional stress conditions in real-time during surgical simulation. Finally, we constructed a comprehensive surgical simulation system, which reproduces whole human aorta structure (with more than Imm inside diameter), reproduce patient-specific pulsatile blood streaming, allowed to evaluate the stress applied to the aorta structure by surgical operations with almost same manner and environment as the practical endovascular intervention. Consequently proposed model, evaluation method and resultant system provides a very valuable platform for evaluating the performance of surgical robots and instruments developed by developers and researchers, and surgical procedures
