New Cardiac Catheter Combines Light and Ultrasound to Measure Plaques (image) University of California - Davis Share Print E-Mail Caption Biomedical engineers at UC Davis have combined intravascular ultrasound with fluorescence lifetime imaging in a single catheter probe that can image the tiny arteries of a living heart. The new catheter can simultaneously retrieve structural and biochemical information about arterial plaque that could more reliably predict heart attacks.
