Listen to the chemical and histological information in biological tissue

Photoacoustic imaging (PAI), as an emerging biomedicine diagnostic technique that has been developed quickly in the past decade, inherits the high spatial resolution of ultrasonography in imaging deep tissue and the high sensitivity of optical imaging in evaluating tissue chemical and physiological information. In this paper, after introducing the basic principles of PAI including both photoacoustic tomography and photoacoustic microscopy, we will review some recent progress of PAI in biomedicine and demonstrate the capability of PAI in detecting the chemical compositions and in evaluating the histological microstructures in biological tissue.

Photoacoustic imaging (PAI), as an emerging biomedicine diagnostic technique, inherits the high spatial resolution of ultrasonography in imaging deep tissue and the high sensitivity of optical imaging. In this review, we introduce the basic principles of PAI and show its irreplaceable advantages in detecting the chemical compositions and in evaluating the histological microstructures in biological tissue.Figure optionsDownload as PowerPoint slide
