Scientific Manager, Human Imaging Core
My previous and ongoing research projects focus on overcoming the real world limitations of MRI that hinder research and clinical applications. I seek solutions to problems such as motion corruption, static field and radio frequency field inhomogeneity, long acquisition times, field of view limitations, and the qualitative nature of most MRI methods. Strategies to overcome these challenges include both hardware and software solutions, alternative data acquisition and reconstruction methods, novel MRI pulse sequences, quantitative imaging methods and associated post-processing tools.
Current research projects include whole-body fat-water MR imaging in both human and animal subjects, non-Cartesian image acquisitions and reconstructions, and compressed sensing acquisitions and reconstructions For more details please visit http://labnodes.vanderbilt.edu/member/profile/id/10556
