Photoacoustic imaging is a promising method for visualizing biological tissues with optical absorbers. This article provides an overview of the rapidly developing field of photoacoustic imaging. Photoacoustics, the physical basis of photoacoustic imaging, is analyzed briefly. The merits of photoacoustic technology, compared with optical imaging and ultrasonic imaging, are described. Various imaging techniques are also discussed, including scanning tomography, computed tomography and original detection of photoacoustic imaging. Finally, some biomedical applications of photoacoustic imaging are summarized.read more

Forward-viewing photoacoustic imaging probe with bundled ultra-thin hollow optical fibers
TL;DR: In this paper, a photoacoustic imaging system composed of a flexible bundle of thin hollow-optical fibers was proposed for endoscopic diagnosis, where the hollow fibers in the bundle were aligned at the input end, so the hollow fiber was sequentially excited by linearly scanning the laser beam at the output end.
