A new endoscopic surgical system integrates 4K Ultra high definition (UHD) technology to improve visibility and allow more precise and safer surgery.

The Olympus (Tokyo, Japan) VISERA 4K UHD delivers images in both 4K (4096 x 2180 pixels) and UHD (3840 x 2160 pixels) resolution, thus providing four times more image information than Full HD, thanks to the Sony (Tokyo, Japan) Exmor R CMOS image sensor in the camera head. The system incorporates an ultra telescope with an extra-low dispersion lens that reduces chromatic aberration, ensuring that it will consistently provide sharp depictions in true colors, even on the fringes of the visible edge.

A one-touch autofocus feature delivers sharp pictures on the surgeon's 55-inch screen at the push of a button, providing an immersive environment and sharp images in full 4K UHD brilliance. The Sony OptiContrast Panel guarantees high-contrast and minimal glare images, while a magnified visualization function allows the surgeon to use the telescope fitted to the VISERA 4K UHD even at some distance from the section being operated on, while still delivering high resolution images.

The 4K and UHD technology also provide surgeons with finer color calibration possibilities by broadening the gamut of color reproduction by a factor of 64, when compared to predecessor models featuringfFull HD technology. The enlarged color spectrum, encompassing around one billion colors, improves the visibility of edges and fine details of delicate tissue, such as blood and lymphatic vessels and nerves. The richer reproduction of reds also assists surgeons in ensuring that incisions are even more accurate.

“The VISERA 4K UHD is part of our aim to provide surgeons with even better support in their challenging and high-precision work, and to thereby help improve clinical outcomes and the quality of life for patients,” said Frank Drewalowski, managing director of Medical Systems at Olympus Europa. “We are convinced that the 4K UHD technology will become a new benchmark in surgical endoscopy.”

The VISERA 4K UHD was developed by Sony Olympus Medical Solutions (Tokyo, Japan), a medical joint venture between Olympus and the Sony Corporation that was founded in 2013.
