混合现实显示技术正在进入手术室

Mixed Reality Displays are Entering the Operating Room

Imagine maneuvering your car through a dark tunnel that bulges unexpectedly in places and then turns sharply through a maze-like passage. The perilous journey feels safer with a light and camera showing the way ahead. It’s even better if digital lines lay out a track, assuring you stay in your lane.

想象一下,你驾驶你的车通过一个黑暗的隧道,在某些地方突然隆起,然后急转通过一个迷宫状的通道。有了灯光和摄像机指引前方的道路,这段危险的旅程会更安全。如果数字线路布置出一条轨道,确保你留在你的车道上,那就更好了。

In a rudimentary way, that scenario illustrates the advantage mixed reality (or augmented reality) is bringing to surgery, starting with the delicate pathways of the sinus. “When you’re doing minimally invasive surgery in a narrow corridor, you want to stay in the corridor, do whatever needs to be done, and not disturb anything around you,” says Martin J. Citardi, a rhinologist at the University of Texas Health Science Center at Houston, who in 2018 became the first in the United States to perform sinus surgery using a blended view of real and digital imagery.

从最基本的角度来看,这个场景说明了混合现实(或增强现实)给外科手术带来的优势,首先是鼻窦的精细路径。“当你在狭窄的走廊里做微创手术时,你想呆在走廊里,做任何需要做的事情,不要打扰你周围的任何事情,”休斯顿德克萨斯大学健康科学中心的鼻科专家Martin J.Citardi说,他在2018年成为美国第一个进行鼻窦手术的人使用真实图像和数字图像的混合视图。

Digital markings superimposed on real-world camera feeds have become commonplace in everyday life, as in the rear-view cameras on cars and the first-down lines in televised football games, but it’s a new phenomenon in surgery. In 2017, the guidance system Citardi used became the first to gain approval from the US Food and Drug Administration for sinus surgery. Two different surgical planning apps designed for HoloLens, Microsoft’s mixed reality headset, have since also garnered FDA approval. Coming soon are the shimmering holograms of sci-fi imagination in surgery itself: A clinical trial is now evaluating whether HoloLens headsets help surgeons and radiologists zap tumors.

在日常生活中,叠加在真实世界的摄像机上的数字标记已经司空见惯,比如汽车上的后视摄像头和电视转播的足球比赛中的第一个底线,但这在外科手术中却是一个新现象。2017年,西塔迪使用的指导系统成为第一个获得美国食品和药物管理局(FDA)批准的鼻窦手术指导系统。为微软的混合现实耳机HoloLens设计的两个不同的手术计划应用程序也获得了FDA的批准。即将到来的是外科手术中科幻想象的闪光全息图:一项临床试验正在评估全息头戴式耳机是否有助于外科医生和放射科医生治疗肿瘤。
