Intravascular Photoacoustic Imaging, a New Type of Medical Imaging Technology

Caption

This image is taken using a new type of medical imaging technology that could diagnose cardiovascular disease by measuring ultrasound signals from molecules exposed to a fast-pulsing laser. The system, called intravascular photoacoustic imaging, takes precise three-dimensional images of plaques lining arteries and identifies deposits that are likely to rupture and cause heart attacks. This cross-sectional view of an artery shows lipids (green) deposited inside the arterial wall Black and white indicate contrast showing the cross-sectional geometry. A publication-quality image is available at http://www.purdue.edu/uns/images/2014/cheng-arteries.jpg.
