Deformation Method of a Blood Vessel by Considering the Inner Pressure for the Purpose of Surgical Simulators

研究的目的是建立一种考虑内压的快速、准确的血管变形方法。为了达到该目的，不仅是作为液体的血液，而且作为弹性体的血管都被表示在粒子模型中，使得血液和血管之间的碰撞检测通过可以应用于血液之间的统一方法来执行。此外，一个快速搜索算法的邻居粒子已经开发和血管模型已经产生的基础上的医疗数据的真实的病人。作为模拟的结果，可以通过考虑内部压力来快速且准确地执行血管的变形。

The purpose of the research is to establish a fast and exact deformation method of a blood vessel by considering the inner pressure. In order to reach the goal, not only the blood, which is liquid, but also the blood vessel, which is elastic body, are represented in a particle model so that the collision detection between the blood and the blood vessel is performed by a unified method that can be applied to among bloods. In addition, a fast search algorithm for neighbor particles has been developed and a blood vessel model has been generated based on medical data of a real patient. As the result of the simulation, it has been possible to perform the deformation of a blood vessel fast and exactly by considering the inner pressure.
