VISERA 4K UHD Endoscopy System gives surgeons four times higher resolution

Surgeons will benefit from particularly-sharp images thanks to integration of 4K Ultra HD technology into Olympus’s VISERA 4K UHD system.

General surgeons will be able to see live 4K surgery being transmitted by this new product at the ALSGBI Annual Scientific Meeting in Southport on 26-27th November.

The VISERA 4K UHD delivers images in 4K resolution (4096 x 2180 pixels) and Ultra HD (UHD) with 3840 x 2160 pixels, providing four times more image information than Full HD.

“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

Ultra high definition

The Sony Exmor RTM CMOS image sensor in the camera head of the VISERA 4K UHD produces detailed, low-noise images. The one-touch autofocus feature delivers sharp pictures on the surgeon’s screen at the push of a button. The system incorporates an ultra telescope with an extra-low dispersion lens that reduces chromatic aberration caused by light dispersion at the visible edge. This ensures that the system will consistently provide incredibly-sharp depictions in true colours, even on the fringes of the visible edge.

Wider colour gamut

4K and UHD provide surgeons with finer colour calibration possibilities by broadening the range of colour reproduction compared by a factor of 64 to predecessor models featuring Full HD technology. An enlarged colour spectrum encompassing around one billion colours is now reality. The system improves the visibility of edges and fine details of delicate tissue, such as blood and lymphatic vessels and nerves. Above all, the richer reproduction of reds assists surgeons in ensuring that incisions are even more accurate.

Magnified visualisation

A 55-inch screen provides a truly immersive environment and displays the razor-sharp images being transmitted from the endoscope in 4K Ultra HD brilliance. Sony’s OptiContrastTM Panel guarantees that images impress with high-contrast and minimal glare. The magnified visualisation 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. The remote position of the VISERA 4K UHD also prevents collisions with other handheld instruments.
