Bottom Line: Photoacoustic (PA) imaging is a hybrid biomedical imaging method that exploits both acoustical Epub ahead of print and optical properties and can provide both functional and structural information.Therefore, PA imaging can complement other imaging methods, such as ultrasound imaging, fluorescence imaging, optical coherence tomography, and multi-photon microscopy.This article reviews techniques that integrate PA with the above imaging methods and describes their applications.

ABSTRACT
Photoacoustic (PA) imaging is a hybrid biomedical imaging method that exploits both acoustical Epub ahead of print and optical properties and can provide both functional and structural information. Therefore, PA imaging can complement other imaging methods, such as ultrasound imaging, fluorescence imaging, optical coherence tomography, and multi-photon microscopy. This article reviews techniques that integrate PA with the above imaging methods and describes their applications.

Schematic of photoacoustic imaging.When a target absorbs pulsed light, photoacoustic (PA) waves are generated via thermoelastic expansion. The PA waves propagate and are detected by an ultrasound transducer. Reprinted from Kim et al. Chem Rev 2010;110:2756-2782 [2], with permission of American Chemical Society.

Mentions: Photoacoustic (PA) imaging is a hybrid biomedical imaging method that exploits both acoustical and optical properties. PA imaging has been evaluated as a preclinical and clinical imaging method in the biomedical field [1-6]. PA imaging is based on the PA effect [7]. When a pulsed laser with a pulse width of a few nanoseconds illuminates a target object, a PA wave can be induced as a consequence of the object’s thermoelastic expansion and subsequent relaxation (Fig. 1) [2]. An ultrasound (US) transducer detects the PA wave, and an image is reconstructed through an imaging process. The initial pressure P (Pa) of a generated PA wave can be expressed as
