In vivo super-resolution photoacoustic computed tomography by localization of single dyed droplets
(PHYSorg.com Physics)

Photoacoustic computed tomography (PACT) is a non-invasive hybrid imaging technique that excites biological tissues with light and detects the subsequently generated ultrasound to form images. PACT combines the advantages of both optical imaging-high optical contrast, and ultrasonic imaging-high resolution and deep penetration in biological tissues. PACT has been widely used for vascular network mapping, functional brain imaging, and tumor detection in deep tissues.
