Page 70 S U R G I C A L I M A G I N G Is 3D the new frontier? "With HD, the curve is beginning to level off," says David Renton, MD, MPH, an assistant professor of surgery at Ohio State University's Center for Minimally Invasive Surgery in Columbus. While the difference between a standard-definition cathode-ray-tube monitor and your first flat-panel HD screen was eye-opening and jaw-dropping, he says, adding more pixels to a high-resolution image is nowhere near as impressive. "The images themselves have gotten about as crystal clear as they're going to get," he says. "The human eye can only see so many details in a picture. The new frontier is 3D." Three-dimensional imaging made its way to laparoscopic surgery by way of stereoscopic microscopes and surgical robotics. "One of the big advances of robotics was 3D," says abdominal surgeon Sharona B. Ross, MD. "Robotic surgery has depth perception, but no tactile response. Laparoscopy is tactile, but with no depth perception. By adding the third dimension to a scope's view, surgeons may be able to do more with laparoscopy." Indeed, some device manufacturers have marketed their 3D scopes, which feature a pair of lenses to capture dual images which combine to create the effect of binocular vision on a flat screen, as a budget and footprint-friendly alternative to a surgical robot, albeit one without the robot's smooth-wristed action and tremor negation. One scope's articulating tip solves a problem commonly experienced by 3D laparo-scopy users, notes Dr. Renton. A fixed 3D scope's dual lenses create a horizon in its image, one which the polarized glasses users must wear to see the depth effect lines up with. "If you turn the camera off of that horizontal axis, the images no longer line up. You lose the horizon, the image becomes a big blur and everyone gets nauseated," he says. An articulating tip, however, enables scope motion to gain a different perspective or see behind organs while
