Title: Variational Methods for Magnetic Resonance Velocity Imaging
Abstract: Magnetic Resonance (MR) velocity imaging is a powerful tool to study the rheology of complex fluids. Fast MR velocity imaging, however, usually requires the sub-sampling of each temporal k-space frame in order to increase temporal resolution. Additional measurement and modeling errors like noise and phase-wrapping make direct Fourier inversion infeasible. In this talk we will present and evaluate two variational approaches - one based on a linear and one on a nonlinear forward model - to reconstruct velocity components from sub-sampled k-space measurements.
