Abstract :
The hypothesis that quantitative blood flow measurements are feasible with the time-intensity based method in photoacoustic imaging using gold nanoparticles as contrast agent is experimentally tested. The in vitro results show good linearity between the measurements and the theory, thus suggesting the potential of relative photoacoustic flow measurements with gold nanoparticles
