How much greater is the resolution of a 4K surgical video
monitor compared with HD (high-definition) monitors?
a. 2x c. 4x
b. 3x d. There is no difference.
c. 4K monitors, also known as ultra-HD, have more than 8 million
pixels (more than 4,000 horizontal and more than 2,000 vertical).
HD monitors, on the other hand, have just over 2 million pixels
(1,920 across by 1,080 up and down). In other words, 4K monitors
have more than 4 times as many pixels as HD monitors. Numbers
aside, the difference in image quality can be astounding when you
see it for yourself.
How big are the scopes
used in today's 4K imaging?
a. 5 mm c. 7 mm
b. 10 mm d. 15 mm
a. The 5 mm scopes allow for smaller incisions, which means less
chance of bleeding, infection and hernias. Previously, 10 mm scopes
were the standard. That's important, because the rate of complica-
tions increases in proportion to the port-site incision.
True or false? To see the 3D image on a heads-up 4K surgical
video, you must wear battery-operated goggles and turn up the
OR lights.
a. True b. False
b. False. With today's most modern equipment, passive goggles
(meaning there's no battery component) let you see 3D images clearly,
