The Applications:

Optoacoustic tomography

Photoacoustic tomography (PAT), an emerging powerful optical imaging modality using optical absorption contrast and ultrasonic resolution, has broken through the fundamental barrier of one TMFP imaging depth (2,4–9). Most importantly, all the key characteristics of PAT are highly scalable
