本文旨在实现心脏手术仿真中心脏跳动的触觉再现和实时可视化。与大多数前述方法不同，作者专注于时间序列数据集，并提出了一种新的活动组织交互模拟框架。该框架处理机械手和跳动的虚拟心脏之间的碰撞的检测和响应。基于物理的心脏自主运动的力反馈也是基于应力-压力模型产生的，该模型适用于充满流体的弹性物体。将一名成年男子的时间序列数据集应用于带有力反馈装置的集成仿真系统。该系统显示心脏跳动的多维表示，并为手术触诊提供基本的训练环境。最后，测量和医学评估的结果证实了所提出的框架所达到的质量和性能。
This paper aims to achieve haptic reproduction and real-time visualization of a beating heart for cardiac surgery simulation. Unlike most forgoing approaches, the authors focus on time series datasets and propose a new framework for interactive simulation of active tissues. The framework handles both detection and response of collisions between a manipulator and a beating virtual heart. Physics-based force feedback of autonomous cardiac motion is also produced based on a stress–pressure model, which is adapted to elastic objects filled with fluid. Time series datasets of an adult man were applied to an integrated simulation system with a force feedback device. The system displays multi-dimensional representation of a beating heart and provides a basic training environment for surgical palpation. Finally, results of measurement and medical assessment confirm the achieved quality and performance of the presented framework.
