Recent progress in photoacoustic imaging technology

Photoacoustic Imaging Technology（PAT） with high contrast,excellent resolution and deep penetration is an emerging noninvasive detecting technology in biomedical applications.This paper introduces the latest progress in PAT,which contains the improvement of image detecting modes,increase of imaging speed,enhancement of imaging resolution and the modification of image reconstruction algorithm.By taking application of PAT to the clinical diagnosis as examples,it describes that the PAT applications have been expanded in biomedical fields.Finally,it overviews the shortcomings of the PAT,and points out that multi-mode combination will a developing trend of the PAT,such as combination of the photoacoustic imaging and the ultrasonic imaging or the photoacoustic imaging and the OCT.Moreover,the molecular PAT based on the contrast agent will also has a good prospect.
