DESCRIPTION (Adapted from applicant's abstract): The applicants propose to develop a virtual reality-based simulator for interventional cardiology. The goal of this work is to simulate the "look and feel" of diagnostic catheterization, percutaneous transluminal coronary angioplasty (PTCA), and coronary stenting with enough accuracy to serve as a platform for the design and evaluation of cardiovascular devices. Emphasis will be placed on validation of the simulator as a teaching and certification instrument for physician training and accreditation. The simulator will be based on the da Vinci catheter insertion simulator for interventional radiology developed at the Centre for Information-enhanced Medicine of the Johns Hopkins University School of Medicine. The simulator will be configured using finite element modeling to provide accurate physical applications of devices such as catheters, guidewires, dilatation balloons and stents. Models of the heart and the treat vessels will be derived from the Visible Human Project and patient-specific data. The development of a high fidelity interventional cardiology simulator will lead to a reduction in health care costs by reducing medical device errors, improving physician performance by reducing the learning curves in which human patients are used, reduce training on patients and animals, and providing a mechanism for maintenance of physician competence.

描述（改编自申请人摘要）：申请人建议 为介入心脏病学开发基于虚拟现实的模拟器。 这项工作的目标是模拟诊断的“外观和感觉”， 导管插入术，经皮腔内冠状动脉成形术（PTCA）， 和冠状动脉支架植入术，其精度足以作为 心血管器械的设计和评价。 重点将 验证模拟器作为教学和认证工具 用于医生培训和认证。 模拟器将基于 用于介入放射学的da芬奇导管插入模拟器 约翰·霍普金斯大学信息增强医学中心开发的 霍普金斯大学医学院。 将配置模拟器 使用有限元建模来提供精确的物理应用 例如导管、导丝、扩张球囊和支架。 心脏和治疗血管的模型将从 可视人类项目和患者特定数据。 的发展 高保真介入心脏病学模拟器将导致 通过减少医疗设备错误来降低医疗保健成本， 通过减少学习曲线来提高医生的表现， 使用人类患者，减少对患者和动物的训练， 提供一种维持医生能力的机制。
