Olympus Colonoscopes
High-resolution HDTV images
In our quest for the best-possible image quality, it was only natural that we add HDTV compatibility to EVIS EXERA II’s impressive features. The HDTV images produced by EVIS EXERA II are composed of more than double the number of scanning lines and horizontal pixels used in conventional video systems. This hundred-percent increase in image information produces a picture that’s incredibly sharp and detailed with virtually no detectable pixelation or artifacts. With HDTV, it is now possible to observe capillaries and subtle mucosal tissue in greater detail throughout the screen area.

HDTV — or high-definition television — offers image quality comparable to film and all the convenience and flexibility of conventional video. With 1,080 effective scanning lines of picture information, compared to 480 for NTSC and 576 for PAL, HDTV delivers picture quality that is more than twice as good as conventional TV. Increased pixel density produces a smooth clear picture whose remarkable detail, and natural colors are unmarred by the pixelation seen in lower-resolution images. This superb quality and realism makes HDTV ideal for demanding imaging applications such as endoscopy.
Highlighting hidden tissue structures
EVIS EXERA II’s NBI capability enhances the visibility of capillaries and other structures on the mucosal surface. The enhanced visibility made possible by NBI may improve examination efficiency by helping to decrease examination time and reduce unnecessary biopsies. You can switch between regular and NBI images at the touch of a button on the scope or on the front panel of the light source.
 

Close Focus
Until now, no endoscope extended it’s depth of field beyond 3mm. Olympus’ High Definition line of Gastroscopes and Colonoscopes employ a newly designated feature called Close Focus Magnification. This feature’s magnification provides a more detailed view by extending the depth of field to 2mm.

Wide-angle 170° field of view
Olympus’ Evis Exera II 180 Series adult colonoscopes are the only endoscopes on the market with an innovative lens that improves the field of view from 140° to an astonishing 170°. This unique feature will reduce the need to angulate the distal tip of the endoscope when looking behind folds and it may even help to decrease examination time.

Universal Platform
Our most versatile endoscopic video system ever, EVIS EXERA II from Olympus encompasses every endoscopic application, in every medical environment. Establishing for the first time a truly universal platform that provides access to the latest developments in video imaging to all medical fields where endoscopes are used, EVIS EXERA II offers an array of advanced yet practical functions that include HDTV, new image processing technologies, autoclavability, integration, and more Fulfilling the needs and aspirations of all practitioners, EVIS EXERA II’s standardization offers efficiency savings too, with high levels of reliability, one universal operating interface for easy staff training, and true flexibility of deployment throughout the hospital.
