Advancements Make Laser-Based Imaging Simpler and Three-Dimensional

There are times when scientific progress comes in the form of discovering something completely new. Other times, progress boils down to doing something better, faster, or more easily.

New research from the lab of Caltech's Lihong Wang, the Bren Professor of Medical Engineering and Electrical Engineering, is the latter. In a paper published in the journal Nature Biomedical Engineering, Wang 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. [Caltech story]
