Interventional Video Tomography (IVT) is regularly used for computer-assisted 3D navigation in ear-, nose, throat, and head & neck surgery in our clinic. We present the technology and its application to collect biopsies of a 5,300 year old, completely conserved male cadaver, the Iceman. IVT links intraoperative live video with medical imaging data sets, realizing real-time surgical guidance in the live video and/or in the medical images. The IVT data contain the video images and the spatial sensor information; this has a large potential for documentation, training, teaching, and telepresence. IVT allowed us to sample the Iceman's mucosa by the minimally invasive endoscopic approach of the maxillary sinus, the nasal cavity, and the larynx, minimizing tissue damage. Visual inspection of the sinuses and the mucosa revealed the typical mucosa of a fresh cadaver, albeit originating from the stone-age.
介入式视频断层扫描（IVT）在我们诊所常用于耳、鼻、喉及头颈外科的计算机辅助三维导航。我们展示了该技术及其在采集一名5300岁、保存完好的男性冰人尸体活检样本中的应用。IVT将术中实时视频与医学成像数据集相连接，在实时视频和/或医学图像中实现实时手术引导。IVT数据包含视频图像和空间传感器信息；这在记录、培训、教学和远程临场方面具有巨大潜力。IVT使我们能够通过对上颌窦、鼻腔和喉部进行微创内窥镜检查的方法采集冰人的黏膜样本，将组织损伤降至最低。鼻窦和黏膜的目视检查显示出新鲜尸体典型的黏膜，尽管其来自石器时代。
