题目：Quantitative Photoacoustic Tomography
摘要：Photoacoustic tomography (PAT) is a non-invasive, non-ionizing, and inexpensive monitoring and imaging technique that uses near-infrared light and acoustic measurements to probe tissue optical properties. Regional variations in oxy- and deoxy-hemoglobin concentration as well as blood flow can be imaged by monitoring spatial-temporal variations in the light absorption and acoustic pressure, giving PAT the special ability to directly measure the quantitative hemodynamic, metabolic, optical and mechanical parameters and neuronal responses to cells (neurons), tissues and organs activation with high spatial and temporal resolution as well as good penetration depth. These capabilities make PAT a unique stand-alone imaging tool and useful complement to fMRI, PET and EEG/MEG in studies of normal physiology and pathology. In this talk, Dr. Yuan will mainly talk about his research work on the development of novel and quantitative photoacoustic tomography (PAT) imaging techniques. It almost covers the major aspect of Dr. Yuan’s research advance in PAT field—from mathematics, physics, reconstruction algorithms and instrumentation to clinical and pre-clinical applications.
