months trialing new technology, including 3D options. But the cameras aren't
there yet. With 3D, we'd still have to use the 10 mm scopes, and we didn't want
to take a step backward."
Worth a closer look
Think of an older cell phone with a low pixel count. If you enlarge a photo on
such a device, the image gets grainy. But on the most recent version of the
iPhone, where the pixels-per-inch is greater, a picture can be blown up without
sacrificing quality. It's the same with 4K imaging.
The higher resolution at a larger image size afforded by 4K means physicians can
get a better picture with a bigger monitor (55 inches is recommended). This trans-
lates to greater visibility for everyone involved in a procedure. And because of the
clarity of detail — 4K images don't blur the closer you get — there's more flexibili-
ty in terms of where a surgical team places the monitor. While most 55-inch HD
monitors are wall mounted, 4K monitors can be placed on roll stands and ceiling
booms that can be easily moved around the surgical field.
Images can be also cropped without sacrificing resolution on a 4K monitor,
which can "tile" multiple images together. That's helpful if you'd like to see, for
example, vital signs on the same screen as the surgical action. In integrated sys-
tems, live images can be wirelessly transmitted and viewed outside the OR.
Pictures that are recorded can then be securely emailed to a patient, meaning
information can be shared faster. And because 4K pictures are clearer, physi-
cians have an easier time explaining to patients what they're seeing.
These systems allow for remote access, so if there are ever issues with the imag-
ing process, product engineers can help from off site, meaning problems get solved
quickly. But because the equipment is intuitive, the transition from HD to 4K
should be seamless.
"This is one of the first times a big leap forward in surgical technology has
resulted in something that's easier to use," says Dr. Smith. "Most of the time,
when new devices are added, extensive training is needed. But not only have 4K
