报告摘要:

Biomedical optical imaging offers rich structural, molecular and functional contrasts, and is emerging as a powerful pre-clinical and clinical tool. However, due to light scattering, conventional optical imaging modalities are limited to shallow regions of about 1 mm within biological tissues, significantly limiting their widespread application. To overcome this optical diffusion limit, we developed two technologies that allow deep light penetration: photoacoustic computed tomography (PACT) and optical wavefront shaping (WFS). In this talk, I will introduce the basic principles of PACT and WFS, present some of our latest results, and discuss future challenges and opportunities.

 

报告人简介:

Cheng Ma received his B.S. degree in Electronic Engineering from Tsinghua University, Beijing, China in 2004.  He obtained his Ph. D. degree in Electrical Engineering from Virginia Tech, Blacksburg, Virginia in 2012. His graduate research focused on developing spectral interferometry, absorption spectroscopy, and optomechanical devices for novel sensing applications. From 2012 to 2016, he was a postdoctoral research associate in the Department of Biomedical Engineering at Washington University in St Louis, St. Louis, Missouri. His postdoctoral research focused on noninvasive high-resolution deep-tissue optical imaging and light delivery using photoacoustic computed tomography and wavefront shaping.  From May 2016 to present, Dr. Ma is an assistant professor in the Department of Electronic Engineering at Tsinghua University. His current research interests include light control in complex media, photon-phonon interaction, photoacoustic imaging, adaptive wavefront control, deep-tissue optical imaging, therapy, and optogenetics. Dr. Ma has published twenty-three papers in peer-reviewed journals, including Nature Photonics, Nature Communications, Optica and Scientific Reports. As a research associate, Dr. Ma served as the co-PI on a project funded by the National Science Foundation. Dr. Ma was one of the recipients of “The Thousand Talents Award for Young Professionals” of China in 2016.
