Haptic reproduction and interactive visualization of a beating heart for cardiovascular surgery simulation
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 stresspressure 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.
