Navigation (image guidance) is an essential tool in modern neurosurgery, and most surgeons use an optical tracking system. Although the technology is accurate and reliable, one often is confronted by line of sight issues that interrupt the flow of an operation. There has been feedback on the matter, but the actual problem has not been accurately quantified, therefore making this the primary aim of this study. It is particularly important given that robotic technology is gradually making its way into neurosurgery and most of these devices depend on optical navigation when procedures are being conducted.
In this study, the frequency and causes of line of sight issues is assessed using recordings of Navigation probe locations and its synchronised video recordings.
The mentioned experiment conducted for a series of 15 neurosurgical operations. This issue occured in all these surgeries except one. Maximum duration of issue presisting reached up to 56% of the navigation usage time.
The arrangment of staff and equipment is a key factor in avoiding this issue.
导航（图像引导）是现代神经外科手术中的一项重要工具，大多数外科医生使用光学跟踪系统。尽管该技术准确可靠，但人们经常面临视线问题，这些问题会中断手术流程。对此已有反馈，但实际问题尚未得到准确量化，因此这成为本研究的主要目的。鉴于机器人技术正逐渐进入神经外科领域，并且这些设备在进行手术时大多依赖光学导航，这一点尤为重要。
在本研究中，使用导航探头位置记录及其同步视频记录来评估视线问题的频率和原因。
对一系列15台神经外科手术进行了上述实验。除了一台手术外，所有这些手术都出现了这个问题。问题持续的最长时间达到导航使用时间的56%。
人员和设备的安排是避免这个问题的关键因素。
