Image-guided surgery has recently been described in the literature as a useful technology for improved functional endoscopic sinus surgery localization. Image-guided surgery yields accurate knowledge of the surgical field boundaries, allowing safer and more thorough sinus surgery. We have previously reviewed our initial experience with The InstaTrak System. This article presents a multicenter clinical study (n=55) that assesses the system's capability for localizing structures in critical surgical sites. The purpose of this paper is to present quantitative data on accuracy and performance. We describe several new advances including an automated registration technique that eliminates the redundant computed tomography scan, compensation for head movement, and the ability to use interchangeable instruments.
图像引导手术最近在文献中被描述为一种有助于改进功能性内窥镜鼻窦手术定位的有用技术。图像引导手术能准确了解手术区域边界，从而使鼻窦手术更安全、更彻底。我们之前回顾了我们使用InstaTrak系统的初步经验。本文介绍了一项多中心临床研究（n = 55），该研究评估了该系统在关键手术部位定位结构的能力。本文的目的是提供关于准确性和性能的定量数据。我们描述了几项新进展，包括消除冗余计算机断层扫描的自动配准技术、头部运动补偿以及使用可互换器械的能力。
