I-Scan - Pentax EPK-i7010 Instructions For Use Manual

i-scan

This video processor includes three, optional preprogrammed modes of i-scan.
i-scan is an optional digital, post-processing imaging enhancement technology, which is intended to be used as an adjunct to
traditional white light endoscopy.
i-scan 1, 2, and 3 are preprogrammed default settings. Only one default setting can be activated at a time. The user is able to
either choose the default settings or change the volumetric options of the settings for customizability.
The i-scan modes 1, 2 and 3 can be accessed by using a pre-programmed button on the endoscope, by using a pre-
programmed foot switch or by pressing a keyboard button.
Surface Enhancement (SE), Contrast Enhancement (CE) and Tone Enhancement (TE) are software
based image enhancement functions that work in combination to produce the enhancements of i-
scan 1, 2 and 3.
 Surface Enhancement (SE)
The software based SE mode allows for enhancement of detailed patterns and micro-unevenness (texture) of the surface
structures of the image.
 Contrast Enhancement (CE)
The software based CE mode allows for enhancement of micro-unevenness (texture) by identifying locally dark areas in the
images and further enhancing them with a slight blue tone.
NOTE
 If [Enhancement], [SE], or [CE] is used, noise may become visible in images on the monitor screen.
 [Enhancement], [CE], [SE] settings are stored in memory even if the processor is turned off.
 Tone Enhancement (TE)
The software based TE mode allows for the adjustment of color contrast in the image to enhance contrast between mucosa
and blood vessels. Each TE setting displays a unique combination of red, green and blue contrast.
WARNING
 If any newly identified irregularities in the endoscopic image are observed during any of the image enhancement
observational modes, immediately return to the normal white light observation mode.
 Do not rely on the image enhancement observational modes alone for primary detection of lesions or for decisions
regarding any potential diagnostic or therapeutic intervention.
The tone and the brightness of the endoscopic image of the i-scan observation are different from the white light
observation. Please use the i-scan observation after a thorough white light examination and reviewing the property of
each mode. i-scan observation is an adjunct to white light endoscopy, and is not a substitute for either a thorough
traditional examination or for histopathological results.
