Biomedical photoacoustic tomography (PAT) provides anatomical,functional,metabolic,molecular,and genetic contrasts of vasculature,hemodynamics,oxygen metabolism,biomarkers,and gene expression.These attributes bring PAT to a wide variety of applications in clinical medicine and preclinical research.We report the development of a real-time PAT imaging system,which integrates signal scanning,image reconstruction and displaying photoacoustic images in real time.An optimized back projection algorithm for PAT imaging is proposed and tested on a latest graphics process unit based card.The whole system is built and tested in an experiment for monitoring moving blood events to validate the real-time performance of this system to image moving events.
