Continuous advances in hardware and software have made it possible to image dynamic processes in the human body in real-time with good quality using MRI. This page gives some information and references about a new reconstruction algorithm for dynamic MRI, which I have developed and implemented while working with Jens Frahm at the Biomedizinische NMR Forschungs GmbH at the Max Planck Institute for Biophysical Chemistry in Göttingen, Germany. When combined with a real-time acquisition method developed by Shuo Zhang et al. , the method yields MRI movies at high spatial and temporal resolution. The method is fast enough to observe turbulence after stirring in a water beaker, visualize swallowing and speaking, and to acquire images of the human heart without synchronization to an ECG .
