Performing Surgery in 4K HD

[evilsofa]

"By increasing resolution to this level we allow the surgeon to be actually immersed in images that surpass the live surgical experience. The resolution approaches that of the human eye but it is combined with 10 fold magnification through the telescopes which operate just inches away from the disease. The progress from regular surgical film technology is like comparing sitting in an HD home theater to watching a video on a cell phone."
