图像引导的神经外科手术需要使用计算机辅助手术系统进行3D导航，该系统实时跟踪手术工具并显示它们相对于术前获取的图像（例如，CT、MRI、fMRI等）的位置。图像引导程序中的一个关键问题是需要导航到图像中突出显示的特定位置，例如图像衍生的功能区域，这些区域没有明显的对应解剖标志-我们将这些位置称为虚拟标志。为了解决这些问题，我们贡献了一种新的交互式可视化技术，为外科医生提供更好的反馈-增强的内联可视化。根据专家评估的结果，我们发现神经外科医生在使用我们的增强内联表示时准确率提高了30%。
Image-guided neurosurgery requires navigation in 3D using a computer-assisted surgery system that tracks surgical tools in realtime and displays their positions with respect to the preoperatively acquired images (e.g. CT, MRI, fMRI etc.) A key problem in image guided procedures is the need to navigate to specific locations highlighted in the images, such as image-derived functional areas, that have no obvious corresponding anatomical landmarks - we refer to such locations as virtual landmarks. To address these issues, we contribute a novel interactive visualization technique to provide improved feedback to surgeons - Augmented inline visualization. Based on the results of an expert evaluation, we found neurosurgeons to be 30% more accurate when using our augmented inline representation.
