Abstract: We aim to develop a novel visualization tool for percutaneous renal puncture training based on augmented reality (AR) and compare the needle placement performance of this AR system with ultrasound-guidedfreehand navigation in phantoms. A head-mounted display-based AR navigation system was developed usingthe Unity3D software and Visual Studio to enable the overlay of the preoperative needle path and the complexanatomical structures onto a phantom in real time. The spatial location of the stationary phantom and the percutaneous instrument motion were traced by a Qualisys motion capture system. To evaluate the tracking accuracy,15 participants (7 males and 8 females) performed a single needle insertion using AR navigation (the number ofpunctures n = 75) and ultrasound-guided freehand navigation (n = 75). The needle placement error was measuredas the Euclidean distance between the actual needle tip and the virtual target by MicronTracker. All participantsdemonstrated a superior needle insertion efficiency when using the AR-assisted puncture method compared withthe ultrasound-guided freehand method. The needle insertion error of the ultrasound-guided method showed anincreased error compared with the AR method (5.54 mm ± 2.59 mm, 4.34 mm ± 2.10 mm, respectively, p < 0.05).The ultrasound-guided needle placements showed an increased time compared with the AR method (19.08 s ±3.59 s, 15.14 s ± 2.72 s, respectively, p < 0.000 1). Our AR training system facilitates the needle placement performance and solves hand-eye coordination problems. The system has the potential to increase efficiency andeffectiveness of percutaneous renal puncture training.

摘要: 本研究的目的是开发一种基于增强现实(AR)的新型经皮肾穿刺训练可视化工具,并比较模型中该AR系统与超声引导徒手导航的针头放置性能。本研究使用Unity3D和Visual Studio软件开发了一种基于头戴式显示器的AR导航系统,可以使术前入针路径和复杂的解剖结构影像实时覆盖到穿刺模型上。我们通过Qualisys 运动捕捉系统来跟踪静止模型和经皮器械运动的空间位置。为了评估跟踪的准确性,15名参与者(7名男性和8名女性)使用AR导航(穿刺次数n = 75)和超声引导下的徒手导航(n = 75)方式进行了单次置针操作。针尖与虚拟目标之间的欧氏距离为置针误差,该距离使用MicronTracker测量。与超声引导徒手穿刺相比,AR辅助穿刺方法具有更好的置针效率。超声引导的置针误差高于AR导航的误差(5.54 mm ± 2.59 mm,4.34 mm ± 2.10 mm,p < 0.05)。同时,超声引导的置针时间也高于AR导航的时间 (19.08 s ±3.59 s, 15.14 s ± 2.72 s, respectively, p < 0.000 1)。结果表明,本研究开发的AR训练系统提升了置针效率并解决了操作者的手眼协同问题。在提高经皮肾穿刺训练的效率和有效性方面,该系统展现出一定的潜力。
