Functional photoacoustic imaging from single cell to organ

(Abstract)

Oxygen metabolism is not only closely associated with tissue functionality, but also plays a key role in many life-threatening diseases, such as ischemic stroke, neurodegeneration, and tumors. In vivo imaging of oxygen delivery in a small-animal disease model is of crucial importance for understanding pathogenic mechanisms and exploring new therapeutic strategies in translational medicine. This talk will introduce functional photoacoustic tomography that can quantitatively image oxygen transport in living tissue from trunk vessel to single red blood cells. Functional photoacoustic tomography can simultaneously quantify multiple parameters, including total hemoglobin concentration, blood oxygen saturation, and blood flow speed, metabolic rate of oxygen at scalable resolutions and depths, potentially opening up many new biomedical applications, such as early cancer detection and noninvasive monitoring brain activities.
