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

Time reversal method with stabilizing boundary conditions for Photoacoustic tomography
Olga Chervova,Lauri Oksanen +1 more
TL;DR: In this paper, an inverse initial source problem that models Photoacoustic tomography measurements with array detectors was studied, and a method that can be viewed as a modification of the so-called back and forth nudging method was proposed.

Curve-Driven-Based Acoustic Inversion for Photoacoustic Tomography
TL;DR: A novel method, named as the curve-driven-based model-matrix inversion (CDMMI), to calculate the model matrix for tomographic reconstruction in photoacoustic imaging is presented, which eliminated the use of interpolation techniques, and thus avoided all interpolation related errors.

In vivo determination of acute myocardial ischemia based on photoacoustic imaging with a focused transducer
TL;DR: The preliminary results show that the photoacoustic signal could identify the myocardium and imply that the intensity and area of photoac acoustic images are the rapid fall of an exponential model with an increase of delaying time after the left anterior descending coronary artery occlusion.

Enhanced sensitivity carbon nanotubes as targeted photoacoustic molecular imaging agents
TL;DR: This work lays the foundations for future in-vivo studies that will use the SWNT-ICG particles as imaging agents administered systemically, and shows great promise for high sensitivity photoacoustic imaging of molecular targets in- vivo.
