Preparatory data analysis for the reconstruction of real-time MRI data

Real-time magnetic resonance imaging (MRI) poses unique challenges related to the speed of data acquisition and to the degree of undersampling necessary to achieve this speed. This Master's thesis introduces and evaluates two pre-processing approaches for these problems: Coil compression to reduce the data volume and a channel selection algorithm to reduce streak artifacts which arise as a consequence of undersampling. Both approaches are tested on real data covering anatomical imaging of the head and of the heart.
