Methods development for functional MRI
My research focuses on development of new imaging methods for functional MRI. The goal of the work is to provide efficient and robust acquisition strategies to study brain function at 3T and 7T. Currently I am exploring the use of hybrid radial-Cartesian 3D EPI for use in functional MRI. The aim of this method is to provide a flexible and motion-robust alternative to standard sampling strategies.
