报告摘要：In this first part of my talk, I will give a brief introduction of the Gordon Center for Medical Imaging at Massachusetts General Hospital and Harvard Medical School and the ongoing PET/MRI research at our Center. In the second part of the talk, I will present our work on high-resolution Magnetic resonance spectroscopic imaging (MRSI). MRSI has been recognized as a powerful tool for noninvasive metabolic studies, but clinical and research applications of this technology have been developing more slowly than was expected. One reason for this situation is the problems of long data acquisition time, poor spatial resolution, and low signal-to-noise ratio (SNR) that have limited the use of the existing spectroscopic imaging techniques for in vivo applications. In this talk, I will present a subspace-based approach, called SPectroscopic Imaging by exploiting spatiospectral CorrElation (SPICE), to high-resolution MRSI. SPICE exploits the partial separability (PS) property of spectroscopic signals and adopts special data acquisition and reconstruction schemes enabled by the PS model to recover high-resolution, high-SNR, MRSI images from sparsely sampled data. I will show our most recent results of high-resolution 1H and 31P-MRSI obtained to demonstrate the capability of SPICE.

报告人简介：Chao Ma received his B.S. and M.S. degrees in Electrical Engineering from Tsinghua University, Beijing, China, in 2004 and 2007, respectively, and his Ph.D. degree in Electrical and Computer Engineering from the University of Illinois at Urbana - Champaign (UIUC), USA, in 2013. He did his postdoctoral training at the Beckman Institute at UIUC before he joined Harvard Medical School (HMS) and Massachusetts General Hospital (MGH) in 2015.
He is now an Instructor at the Department of Radiology at HMS and an Assistant in Physics at the Gordon Center for Medical Imaging at MGH. His research interest includes MR spectroscopic imaging, cardiac MRI, PET/MRI, pulse sequence design, and image reconstruction. Dr. Ma was awarded a Beckman Graduate Research Fellowship and a Beckman Postdoctoral Fellowship from UIUC in 2010 and 2013, respectively. He was a recipient of the Summa Cum Laude and Magna Cum Laude awards, the second-place poster award in Hardware and Interventional Imaging Category, and the first-place poster award of the MR Spectroscopy Study Group, all from the International Society for Magnetic Resonance in Medicine (ISMRM). He was selected as a Junior Fellow of ISMRM in 2016. He was also a co-author of a best student paper award finalist paper in IEEE ISBI 2015.
