Paper Abstract

When we consider the needle visualization in the field of point of care by utilizing the photoacoustic imaging system, and using the conventional solid state laser light source, the issue arises such as device size and not a green system due to the high power consumption. Therefore, we aimed at an environmentally friendly and compact system with low power consumption by using a NIR-LED array light source. The intensity of NIR-LED light is weak, but, by averaging photoacoustic signals with multiple pulse, we have improved S/N of the photoacoustic signal. As a result, we’ve achieved penetration depth of 30mm.
