staff should be able
to easily position the
screens so they can
view the images
they want, where
and when they want
them," says Mr.
Mignault. "That will
help the case to go
faster and
smoother."
From chip to screen
The near true-to-life 4K ultra-high-definition resolution is achieved via
computer-generated images captured by a camera chip, broken down
into bits and bytes, and reassembled for display on a monitor. Imaging
systems can't turn a low-quality image into a high-quality image, but
they can degrade image quality. "The goal is to preserve the high-qual-
ity original and show it in the best way possible," says Mr. Mignault.
Ultra-high-definition signals send video signals with more digital
information than standard HD to video monitors, which use the infor-
mation to display images in greater detail. "The trained eye of sur-
geons is able to notice the subtle differences of the transitional lines
between the intestine and the lining of the walls," says Mr. Mignault.
