Olympus has recently launched the VISERA 4K UHD surgical endoscopy system across Europe. Six years ago we already reported on the first laparoscopic surgery being performed in 4K using an experimental setup, but it has taken a while for components to be reduced to the size needed for regularly usable laparoscopic cameras. This is one of the first integrated endoscopy systems on the market to deliver 4K resolution (4096 x 2180 pixels) and Ultra HD (UHD, 3840 x 2160 pixels) video providing four times more image information than Full HD.
The system was developed by a joint-venture of Olympus and Sony and uses a Sony Exmor R CMOS image sensor in the camera head. There is a one-touch autofocus feature and the system uses an extra-low dispersion lens that reduces chromatic aberration caused by light dispersion at the visible edge. A wide color-gamut means that the range of color that can be reproduced is increased by a factor of 64 compared to predecessor models, improving visibility of edges and fine details of delicate tissue.
Of course, such a camera system begs for a great display and this is provided by a 55-inch 4K Sony panel. A magnified visualization function allows the surgeon to use the telescope fitted to the VISERA 4K UHD even at some distance from the part of the body being operated on, while still delivering high-resolution sharp images. Even at two times digital zoom you still have Full HD images. Used this way, collisions or “sword-fighting” with other laparoscopic instruments are reduced. The video below appropriately shows the system in all its glory in a 4K Youtube video (click through to Youtube to make sure the 4K option is activated):
