Dartmouth physicians and engineers are collaborating to test new imaging techniques to find breast abnormalities, including cancer. Results from their latest study, which involved magnetic resonance-guided near-infrared imaging, appear in the May 22 issue of the Proceedings of the National Academy of Sciences (PNAS).
"This paper is the culmination of five years of work to build a completely new type of imaging system, which integrates magnetic resonance imaging (MRI) and near-infrared imaging (NIR)," says Brian Pogue, associate professor of engineering and one of the authors of the study.
He explains that because infrared light is sensitive to blood, researchers can locate and quantify regions of oxygenated and deoxygenated hemoglobin by sending infrared light through breast tissue with a fiber optic array. This might help detect early tumor growth and characterize the stage of a tumor by learning about its vascular and cellular makeup.

Physicists from the University of Würzburg have designed a light source that emits photon pairs. Two-photon sources are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape.
So-called monolayers are at the heart of the research activities. These "super materials" (as the prestigious science magazine "Nature" puts it) have been...
Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...
