mal," says Ms. Alexander. 4K is derived from a 3840 x 2160-pixel matrix, or more than 8 mil- lion pixels compared with standard HD's 2 million pixels. The more pixels you have on the screen, the better the image quality. This increased clarity is especially apparent when magnifying images on large — typically 55-inch — monitors, says Daniel D. Eun, MD, chief of robotic surgical services at Lewis Katz School of Medicine at Temple University in Philadelphia, Pa. "That's where you can really see the difference between HD and 4K," he says. Though there's little research clinically proving that 4K makes a dif- ference in surgical outcomes, Ms. Alexander says her surgeons are more than convinced of its benefits, especially since they have expanded their service line due to their increased ability to see intra- operatively. Some of her physicians also say the system lets them complete procedures more quickly and safely because the high level of definition lets them see every anatomical detail. "The latest 4K systems also offer more than a pretty picture. At least one manufacturer's system has an autofocus feature, which keeps the surgeon's image sharp as he changes location or settings in the surgical field. Additionally, 4K scopes also come in 5 mm size — an improve- ment on the larger 10 mm options of the past — and most scopes now are fully autoclavable to make reprocessing easier. Some, though, aren't sure that 4K is worth the high cost — at least not yet. Seeing in 4K means acquiring both 4K-compatible monitors and cameras, which can cost hundreds of thousands of dollars, and some say their HD images are all they need for now. "Surgical moni- tors are not necessarily used to diagnose," points out Stacy Lund, BSN, RN, CNOR, MSSL, director of surgical services at Stanford Medical Center in Fargo (N.D.). 1 1 6 • O U T PA T I E N T S U R G E R Y M A G A Z I N E • D E C E M B E R 2 0 1 7
