Review on Progress of Quantitative Photoacoustic Tomography

SUN Zheng;ZHENG Lan;Department of Electronic and Communication Engineering,North China Electric Power University;  
Photoacoustic tomography( PAT),an emerging medical imaging modality,combines the high resolution of ultrasonic imaging and high contrast of optical imaging. Current research on PAT includes two inverse problems,i. e.,constructing the distribution of initial acoustic pressures according to the photo-acoustic signals generated by the tissues and estimating the optical absorption and scattering coefficients of the tissues within the imaging region based on the results of the first inversion. The latter,known as quantitative photoacoustic tomography( q PAT),is in general a nonlinear ill-posed problem. This paper summarizes current algorithms for solving the q PAT inversion.Related advantages and limits as well as perspective studies are discussed.
