Abstract

Photoacoustic imaging is a non-invasive imaging technology that can be combined with optical absorption contrast and detection of acoustic wave for structural, functional, and molecular imaging. Especially, optical-resolution photoacoustic microscopy (OR-PAM) can provide a high spatial resolution with a micron-scale. In this study, we have developed laser-scanning OR-PAM, which could obtain in-vivo photoacoustic ophthalmic angiography. For high speed image acquisition, we used a nanosecond pulsed laser with a 300 kHz-pulse repetition rates. In addition, we carried out parallel signal processing using a graphics processing unit to enable fast signal processing. Therefore, we successfully obtained maximum amplitude projection images of microvasculature in anterior and posterior segments of mouse’s eye with real-time display of 0.98 fps.
