Abstract

Photoacoustic imaging is a promising technique in practical medicine to image biological tissue's function and diagnose internal organs. In this paper, a new photoacoustic imaging modality for imaging internal organs was presented. A laser which wavelength is tunable was coupled into a multimode optical fiber. And the fiber was inserted into the inner tract of the samples to deliver light for exciting photoacoustic signals. The outgoing PA signal was detected by a focal ultrasound transducer with long focal length which was placed on the surface of the samples. By transducer scanning, we obtained a 2D cross-section photoacoustic image. Finally, we evaluate this system's performance and demonstrate its capabilities by imaging phantoms with complex structure.
