Commercial 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.
Our 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.
Experienced 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.
This paper presents the first simulator to train the Seldinger technique. The preliminary results confirm its utility for interventional radiology training.
商业介入放射学血管模拟器模拟器械导航和器械部署，但没有一个支持提供血管树初始进入通道的 Seldinger 技术。本文提出了一种新的虚拟环境，用于教授这一核心技能。
我们的模拟器结合了两种触觉设备：使用虚拟针和导管进行血管穿刺，以及导丝操作。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，而有效的碰撞检测和碰撞响应允许实时交互。
经验丰富的介入放射科医生评估了我们模拟器的触觉组件，认为它们具有真实感和准确性。血管穿刺触觉设备提出了一个用于模拟 Seldinger 技术的初步原型。与血管模型中的真实仪器相比，我们的模拟器展示了真实的仪器行为。
本文介绍了第一个用于培训 Seldinger 技术的模拟器。初步结果证实了它在介入放射学培训中的实用性。
