PV-7000 Technology
4 Led multi lightsource
BLI
Blue Light Imaging
:<3:
high-contrast images of
superficial mucosal structures
micro vessels
Using multi light Tech, get narrow band light(Blue-violet) and white light
LCI
Linked Color Imaging
:<3:
uses
same
illumination spectrum profile as
BLI-bright
Digital signal processing
increases the color contrast
by expanding the color nearby mucosal “Redness”
IEE
đź’– NBI
is an optical imaging technology
works by
filtering the white light
into specific
light wavelengths
that are absorbed by hemoglobin and penetrate only the surface
of human tissue
Capillaries
on the muscosal surface are displayed in
brown
and
vein
in the submocosa are displayed in
cyan
NBI is filtering white light, leaving necessary light.
It is a technique of “subtraction of light”.
i-scan OE
The i-scan OE function is a
technology of combining bandwidth-limiting light with digital image processing
Pentax
enable the display of the
surface structures of the blood vessels, glandular ducts and mucosal membranes in higher contrasts than white light
