About The Cover

Ultrahigh-resolution images of a rabbit trachea (~6 mm diameter) obtained in vivo by catheter-endoscope-based optical coherence tomography. The technique probes the tissue with light from a fiber optic source by collecting photons reflected from features in the wall. It is one of the imaging technologies transforming fields including medical diagnosis, cell biology, and materials science. See 2037, the special News section (1981), and links to related items.
