NEW ARTICLE; Conventional wisdom on tissue imaging turned on its head

An international team of experts has made a technological breakthrough for one of the most important forms of imaging: optical coherence tomography (OCT). They believe that selective collection of multiple scattered light may lead to improved image contrast at depth.

The team from the University of Adelaide, Australia, Technical University of Denmark (DTU), the University of St Andrews, Scotland and Aerospace Corp., USA, has challenged conventional wisdom which says that an OCT signal is dominated by light and has undergone a single backscattering event, whereas light scattered (scrambled) many times is detrimental to image formation.
