Two-Mode Imaging System More Efficient for Tumor ID
TUCSON, Ariz., and ST. LOUIS, June 23, 2014 — Removing cancerous tumors can be a delicate process, requiring surgeons to pinpoint their exact location. A new technology has demonstrated that ability in a more effective way than with conventional methods. A dual-mode imager developed by a team from the University of Arizona and Washington University in St. Louis combines two systems — near-infrared fluorescence imaging and visible light reflectance imaging — into one package. The near-IR imaging detects marked cancer
Brain-Mapping Device Aids PTSD Study
