经皮冠状动脉腔内成形术（Percutaneous transluminal coronary angioplasty，PTCA）是一种微创的图像引导技术，用于治疗冠状动脉疾病。经皮冠状动脉腔内成形术（PTCA）要求医生在操作时具有良好的手眼协调能力。因此，PTCA的培训非常强调手眼协调的技能培养。我们一直在开发用于医疗模拟的虚拟现实（VR）技术。在本文中，我们将讨论基于VR的仿真问题，以增强PTCA手术的手眼协调。从PTCA手术的特点出发，我们研究了VR在PTCA医生培训中可以发挥什么作用。然后，我们描述了一个计算机化的PTCA培训系统，我们已经开发，这是由触觉界面和视觉界面。该系统的设计使得真实的PTCA器械（包括导管和导丝）可用于模拟CathLab的要求。后端计算引擎支持实时和逼真的PTCA模拟。
Percutaneous transluminal coronary angioplasty (PTCA) is a minimally invasive image-guided technique for treatment of coronary diseases. PTCA procedure requires physicians to have good skills of hand–eye coordination in performing the operation. Training of PTCA thus very much emphasizes skill building for hand–eye coordination. We have been developing virtual reality (VR) technology for medical simulation. In this paper, we will address the issue of VR-based simulation for the enhancement of hand–eye coordination for PTCA operation. Starting from the characterization of PTCA procedure, we examine what roles VR can play in training of PTCA physicians. We then describe a computerized PTCA training system we have developed which is composed of a tactile interface and a visual interface. The system is designed in such a way that real PTCA devices (including catheters and guide-wires) can be used to mimic the requirements of the CathLab. The backend computational engine supporting the real-time and realistic PTCA simulation is also presented.
