Bioimaging Technique Isolates Moving Tissue

Facebook Twitter LinkedIn Email Comments
Light-guiding technology could take scientists on a journey inside blood vessels. The new technology — time-reversed adapted-perturbation (TRAP) optical focusing, developed by a team at Washington University in St. Louis — guides light into tissue to seek movement, such as blood flow, that is obscured by highly scattering media. This light appears differently than light that passes through stationary tissue. The researchers demonstrated that light passing through stationary tissue can be subtracted, leaving only the scattered light caused by motion. That light can then...Read full article
