With the increase of ischemic diseases of the circulatory system in Japan, the necessity for cardiovascular intervention continues to increase. However, because intervention operations have been developed only recently, the education system for the corresponding specialists in our country has not been established yet. In this study, an intervention educational support system using a virtual reality (VR) technique was developed. Of course, intervention includes percutaneous transluminal coronary angioplasty (PTCA). PTCA is an operation enlarging the stenosis of the coronary artery with a balloon through a guide catheter. The technique that lets the guide wire for the PTCA balloon cross the stenosis is one of the most difficult. A simulation system for the manipulation of a torque device for the PTCA guide wire was developed with this technology for VR. In virtual space, reconstitution of the 3-dimensional coronary artery with atherosclerosis was performed, and the virtual PTCA system was produced experimentally. An interesting system was produced experimentally as a system for the training of doctors studying to become interventional specialists. After the system was combined with an Expert system for treating ischemic heart diseases, its usefulness was steadily increased. With the development of more sophisticated VR methodology in the future, a PTCA training system without using a patient will be embodied.
随着日本循环系统缺血性疾病的增加，心血管介入的必要性持续上升。然而，由于介入手术是最近才发展起来的，我国相应专科医生的教育体系尚未建立。在本研究中，开发了一种使用虚拟现实（VR）技术的介入教育支持系统。当然，介入包括经皮腔内冠状动脉成形术（PTCA）。PTCA是一种通过引导导管用球囊扩大冠状动脉狭窄的手术。使PTCA球囊导丝穿过狭窄部位的技术是最困难的技术之一。利用这种VR技术开发了一种用于PTCA导丝扭矩装置操作的模拟系统。在虚拟空间中，对患有动脉粥样硬化的三维冠状动脉进行了重建，并通过实验制作了虚拟PTCA系统。作为一个培训立志成为介入专科医生的医生的系统，通过实验制作了一个有趣的系统。该系统与治疗缺血性心脏病的专家系统相结合后，其效用稳步提高。随着未来更先进的VR方法的发展，将实现一种无需使用患者的PTCA训练系统。
