这项工作提出了一种新的增强现实方法的评估，用于可视化的实时指导的消融工具，以肿瘤开放的肝脏手术。该方法使用便携式图像覆盖设备，直接集成到肝脏手术导航系统中，直接在肝脏表面显示引导图形和潜在的解剖结构。该引导应用程序生成从当前消融针尖到肿瘤中心的轨迹。针头对准引导和深度信息直接显示在肝脏表面，为引导消融工具尖端指向目标肿瘤提供直观的实时反馈。对猪肝组织的引导视觉反馈的验证表明，该系统在轨迹规划和肿瘤靶向方面是有用的。增强现实制导很容易看到，消除了视线转移的需要，与导航程序本身相比，实施时不会带来任何及时或程序上的开销。
This work presents an evaluation of a novel augmented reality approach for the visualisation of real time guidance of an ablation tool to a tumor in open liver surgery. The approach uses a portable image overlay device, directly integrated into a liver surgical navigation system, to display guidance graphics along with underlying anatomical structures directly on the liver surface. The guidance application generates trajectories from the current ablation needle tip to the centre of the tumor. Needle alignment guidance and depth information are displayed directly on the liver surface, providing intuitive real-time feedback for guiding the ablation tool tip to the targeted tumor. Validation of the guidance visual feedback on porcine liver tissue showed that the system was useful in trajectory planning and tumor targeting. The augmented reality guidance was easily visible, removed the need for sight diversion and was implemented without imposing any timely or procedural overhead when compared to a navigated procedure itself.
