Using a new high-speed, high-resolution imaging method, researchers at Washington University were able to see blood flow, blood oxygenation, oxygen metabolism, and other functions inside a living mouse brain at faster rates than ever before.

The new method is called “photoacoustic microscopy” (PAM), a single-wavelength, pulse-width-based technique developed by Lihong Wang, PhD, the Gene K. Beare Professor of Biomedical Engineering in the School of Engineering & Applied Science, and his team.
