Talk Title: Better and Faster Images of the Thinking Brain

Series: Medical Imaging Seminar Series

Abstract: Functional brain imaging using MRI (functional MRI or fMRI) has been available for about 20 years, and yet the technology of fMRI has continued to evolve quite rapidly. In this presentation, I will present that basic physiology and methods for fMRI and then discuss several advances to acquisition and image reconstruction for fMRI. I will explore a new approach for fMRI that reuses the MRI signal, thus potentially improving the signal strength and signal-to-noise ratio of fMRI studies. The technology of MRI excitation required to implement this approach will be discussed. I will also discuss and demonstrate a method to acquire multiple simultaneous slices using a non-Cartesian acquisition method. Lastly, I will discuss a new image acquisition and reconstruction approach that makes use of mathematical concepts in sparse sampling and low-rank signal representations. This approach has the potential to speed substantially the fMRI acquisition to allow the separation of undesired physiological signals and the imaging of dynamic network processes in the human brain.
