Superthin 3-D Endoscope

摘要

In an endoscope meant to pene-trate the brain, look at a fetus, or thread through tiny ducts, smaller is better. But the endoscopes that produce the clearest 3-D images use cameras several millimeters wide—too big to go many places in the body. Now researchers at Massachusetts General Hospital in Boston have demonstrated an endoscope that's just 350 micrometers wide and sends back 3-D images that are as clear as those produced by larger endoscopes.
