Provides four times more information than conventional full HD imaging systems
The VISERA 4K UHD System Concept
Olympus is always trying to achieve laparoscopic visibility equivalent to open surgery by developing HD video imaging systems with advanced technologies.
Using 4K technology, Olympus is now striving to make laparoscopic visibility even better than open surgery by adding features such as ultra-high-definition, wider colour gamut, and magnified visualisation.
Getting Closer. Seeing More.
Looking at a suspicious tissue structure at close proximity is the key to assessing it successfully; the closer you are, the more information becomes visible. And, clearly, improved visibility enables surgeons to guarantee more precise, safer procedures.
The Olympus VISERA 4K UHD provides four times more information than conventional full HD imaging systems. It supports 4K UHD (3840 × 2160) and full 4K (4096 × 2160) resolution. Four times more information means four times more detail; compared to conventional Full HD, a tissue structure moves 50 percent closer to the eye. This being so, 4K technology can make laparoscopic visibility even better than open surgery.
Realistic Colours. Realistic Differences.
The VISERA 4K UHD system adopts the 4K colour format, generating a wider colour gamut (WCG). WCG gives a remarkable increase in colour: reds, greens, blues, and yellows on the screen appear richer and stronger, and the whole image becomes more realistic. In practical terms, WCG enables rich colour reproducibility and provides the most suitable colours for each surgical discipline.
Surgeons benefit from WCG during a procedure because it makes for the easier determination of tissue boundaries such as fat, nerves, and vessels. And that ensures better visualisation of blood vessels and lesions.
Becoming Completely Immersed in the Procedure.
VISERA 4K UHD magnified visualisation gets surgeons even closer to every detail. Images appear physically larger, enabling surgeons to observe the fine patterns and structures of tissues in high detail, even when enlarged. This in turn means a safer and more visible operating field, and also helps to prevent mist and smoke; “sword fighting” with hand instruments is no longer necessary.
Even at 2.0× zoom, VISERA 4K UHD magnified visualisation is equivalent to full HD resolution – just zoom in and move the scope away from the operating field. On a 55” 4K UHD monitor, the image creates a sense of immersion that allows the entire OR team to focus completely on the surgical procedure.
