"Hot" objects in space emit UV radiation as well. Ultraviolet: Ultraviolet radiation is emitted by the Sun and are the reason skin tans and burns. Fireflies, light bulbs, and stars all emit visible light. In space, infrared light helps us map the dust between stars. Infrared: Night vision goggles pick up the infrared light emitted by our skin and objects with heat. Microwave: Microwave radiation will cook your popcorn in just a few minutes, but is also used by astronomers to learn about the structure of nearby galaxies. Radio waves are also emitted by stars and gases in space. He estimates that it will only be a few years before the technology is good enough to use in real operations – but it could be decades before they are deemed safe enough for real patients, he says.Radio: Your radio captures radio waves emitted by radio stations, bringing your favorite tunes. ![]() ![]() “The world of surgery is quite a conservative one,” he says. They hint at what is possible but there are huge technological and regulatory hurdles to overcome before they become a reality. Brain surgery is another area where it might be useful to have highly detailed overlays that help a surgeon know exactly where to operate.īut all of these devices are still a long way from making their way into surgical theatres, Ahmed says. Scopis, an augmented reality software firm, has created a similar system designed to help spinal surgeons track the position of their patient’s vertebrae during an operation. “For certain operations and for certain specialities the system sounds very useful,” Ahmed says. It could be coupled with touch-sensitive surgical tools that warn surgeons when they get too close to a nerve, he says, or include virtual projections of the tools themselves so surgeons carrying out keyhole surgery can keep an eye on what they are doing without needing to look at a real-time video of the operation on a screen. ![]() “It is a very embryonic technology,” he says.Įven so, Karger has a wishlist of features such a system could eventually have. Karger admits it will be years before it is tested with real patients. The system is interactive, too: using hand gestures the surgeon can tap on an organ to remove it from their view, allowing them to take a closer look at the area they are operating on.Īs the image is supposed to map exactly onto the patient, it must be pinpoint accurate to prevent surgical mistakes. This image is then plugged into the Microsoft HoloLens headset, so that the surgeon sees the virtual 3D organs on the patient’s body. Karger’s augmented reality system uses MRI and CT scans to build up a 3D image of the inside of a patient’s body, with different organs automatically colour-coded by software. ![]() But he believes they could be precursors to fully automated surgical systems. “We can’t trust these systems at the moment,” he says. “We can take these very complicated specialist procedures and make them accessible to far less specialist surgeons,” he says.īut Shafi Ahmed, a surgeon at Royal London Hospital who live-streamed an operation in virtual reality last year, thinks that no amount of help from augmented reality can replace the hands-on experience of a specialist surgeon. Later versions of the system could include real-time feedback to help guide less experienced surgeons through complicated procedures, says Karger.
