Abstract

LED-based photoacoustic systems have potential to diagnose diseases and tumors with high sensitivity and specificity at a cost that is affordable for all clinics. However, the expensive high-power pulsed Q-switch lasers still provide better image quality than LEDs. They also use piezoelectric transducers that are limited in sensitivity, and noise when miniaturized. Here, we present a low-cost LED-based photoacoustic imaging system with our highly sensitive optomechanical ultrasound sensor (OMUS), which is only limited by thermomechanical noise. In future, the cost of the OMUS read-out and multiplexing will enable clinical translation of in vivo small animal studies.
