报告内容提要
By combining the sensitive optical absorption contrast and high ultrasound resolution, photoacoustic tomography (PAT) emerges as a novel non-invasive, non-ionizing biomedical imaging modality. PAT can break through the barrier in the imaging depth of pure high resolution optical imaging methods. In addition, it provides both in vivo functional and molecular images. Over the fast development during the past decade, PAT has successfully obtained many achievements in small animal and pre-clinical experiments. Our research team are developing several imaging systems based on this novel imaging modality. We give a brief review of PAT in biomedicine, including the fundamental mechanism, diverse research fields and potential for broad clinical applications.

报告人简介
Dr. Changhui Li received his B.S. degree from the Department of Technical Physics and M.S. degree from the Department of Physics of Peking University, China, in 1997 and 2000, respectively, and the M.S. and Ph.D. degrees from Department of Physics of Texas A&M University at College Station, TX, in 2002 and 2006, respectively. He did his postdoctoral research in the Optical Imaging Laboratory under Dr. Lihong Wang in the Department of Biomedical Engineering at Washington University in St. Louis from 2006 to 2010.

He is currently a faculty member in the Department of Biomedical Engineering at Peking University. Dr. Li’s research interests include photoacoustic tomography, fluorescence tomography, and the study of radiative transfer in the turbid medium.

Dr. Li has published 22 scientific SCI journal papers, co-authored one book chapter. He also serves as a guest associate editor for Medical Physics.
