目的商业介入放射学血管模拟器模拟仪器导航和设备部署，尽管没有一个支持Seldinger技术，该技术提供了对血管树的初始访问。本文提出了一种新颖的虚拟环境来教授这一核心技能。方法我们的模拟器结合了两种触觉设备：虚拟针和导管的血管穿刺术和导丝操作。模拟软件显示仪器与血管的相互作用。仪器使用质量弹簧近似建模，而高效的碰撞检测和碰撞响应允许实时交互。结果经验丰富的介入放射科医生评估我们模拟器的触觉组件逼真和准确。血管穿刺式触觉装置提出了模拟塞尔丁格技术的第一个原型。我们的模拟器与血管模体中的真实仪器相比，呈现了真实的仪器行为。结论本文提出了第一个训练Seldinger技术的模拟器。初步结果证实了其在介入放射学训练中的应用价值。
PurposeCommercial interventional radiology vascular simulators emulate instrument navigation and device deployment, though none supports the Seldinger technique, which provides initial access to the vascular tree. This paper presents a novel virtual environment for teaching this core skill.MethodsOur simulator combines two haptic devices: vessel puncture with a virtual needle and catheter and guidewire manipulation. The simulation software displays the instrument interactions with the vessels. Instruments are modelled using a mass-spring approximation, while efficient collision detection and collision response allow real time interactions.ResultsExperienced interventional radiologists evaluated the haptic components of our simulator as realistic and accurate. The vessel puncture haptic device proposes a first prototype to simulate the Seldinger technique. Our simulator presents realistic instrument behaviour when compared to real instruments in a vascular phantom.ConclusionThis paper presents the first simulator to train the Seldinger technique. The preliminary results confirm its utility for interventional radiology training.
