New research from the lab of Caltech's Lihong Wang, the Bren Professor of Medical Engineering and Electrical Engineering, and postdoctoral scholar Yide Zhang show how they have simplified and improved an imaging technique they first announced in 2020. • That technique, a form of photoacoustic imaging technology called PATER (Photoacoustic Topography Through an Ergodic Relay), is a specialty of Wang's group. • In photoacoustic imaging, laser light is pulsed into tissue where it is absorbed by the tissue's molecules, causing them to vibrate. Each vibrating molecule serves as a source of ultrasonic waves that can be used to image the internal structures in a fashion similar to how ultrasound imaging is performed. • More info: https://www.caltech.edu/about/news/ad...
