摘要:
针对血管内介入手术模拟建模与碰撞消除方法存在的不足,提出了一种多体-双层的导管/导丝组合体模型及基于几何分析和旋转角传播的快速碰撞消除方法,并开发了一个实时的三维介入手术模拟系统,模拟导管/导丝在实际血管中的运动行为. 该多体-双层模型由若干分段组成,每一分段代表了一段导丝、导管或两者兼有的组合体,导丝和导管的半径定义不同,材料属性不同,但每一分段长度相同.模型的运动通过碰撞检测和消除加以引导,抵达目标位置后对该模型施加松弛过程使其状态与实际状态更加吻合.实验结果表明,导管/导丝模型的运动状态与给定的材料参数密切相关,模拟可以达到实时的要求,方法可靠有效,有望应用于临床.
Abstract:
To overcome the limitation of modeling and collision cancellation in endovascular intervention simulation, a multibody-bilayer model representing the combination of guide catheter and guide wire is proposed, and a fast collision cancellation algorithm based on geometric analysis and angular propagation is put forward. A 3D real time simulation system is developed for the evaluation of the behavior of guide catheter-wire combination inside specific patient vasculature. The multibody-bilayer model is considered as a chain of many segments. Each segment represents a segment of guide wire or catheter or both. The guide wire and catheter are defined with different radius, different properties, but with the same length for each segment. The motion of guide wire and catheter inside vascular is guided by the collision detection and collision cancellation algorithm. A relaxation procedure is applied to the model to achieve more realistic status when the model arrives at the target location. The experimental results show that the behavior of the guide catheter-wire combination inside vasculature depends on the defined material parameters, and real time simulation can be achieved. The simulation system is effective and promising in clinical application.
