 Abstract photoacoustic tomography, PAT, is a promising medical imaging technique, which uses light to generate sound waves inside the body. This allows for visualization of internal structures without the need for ionizing radiation or radioactive traces. However, current PAT systems are limited by their bulky size and low sensitivity. To address these issues, researchers at the University of California, Barkley developed a new type of sensor array made from shellcogenide glass, which has a much higher sensitivity than existing sensors. Additionally, they used a digital optical frequency comb, DOFC, to enable parallel interrogation of the sensor array, allowing for faster image acquisition. This combination of technologies allowed them to obtain clear images of moving objects such as leaves and zebrafish, demonstrating the potential of this technology for future medical applications.
