Paper Abstract

We’ve developed NIR-LED array light source module for photoacoustic imaging system, which is ultra-small and consumes extremely low power. Conventional photoacoustic imaging system uses solid state laser light source, which consumes large amount of electricity. Instead, we’ve developed high intensity NIR-LED chips on a 1cm x 6cm board, which produces approx. 1.0kW output power and obtained photoacoustic signal by driving NIR-LED light source module with about 100 ns pulse. Comparing to the laser light source, our module is much smaller than 1/15000 the volume and less than 1/1000 the power consumption approximately. We’ve achieved penetration depth of 30mm.
