a. True. Today's navigation systems let surgeons set alarms when they
get too close to the area. For example, ENT surgeons may want a warn-
ing when an instrument gets within 2 or 3 mm of an optic nerve.
A 4K display with 3D projection can make it easier for eye sur-
geons to teach, can reduce musculoskeletal injuries and can
improve OR efficiency.
a. True b. False
a. True. Surgery no longer has to be done under a microscope, mean-
ing that residents don't have to sit next to surgeons and look through
a side view of the scope at a flat image to observe. The ergonomics,
meanwhile, are better for surgeons, who aren't hunched over their
microscopes all day, and everyone in the OR can see precisely what's
happening during surgery, which makes it easier for them to remain
engaged and anticipate the next steps in a given procedure.
Among the image-enhancement capabilities available with
today's surgical video systems are technologies that provide:
a. Fluorescence imaging of injected dye
b. Light filters that use selected wavelengths to provide contrast-
enhanced views of the mucosal surface and the vascular net-
works beneath it
c. Algorithms that help surgeons see through the fog, smoke and
debris of arthroscopy
d. All of the above
d. All of the above. Not only are images more detailed, but one of the
hallmarks of recent technology is that it allows users to much more
