Résumé

This work investigates the role of the filters implemented on modern ADCs for the reconstruction of magnetic resonance images. We analyze both from a theoretical and experimental point of view the effects of these filters and demonstrate how it may lead to severe degradation of the reconstructed images when using modern sampling patterns. Based on these findings, we propose a mathematical model and a numerical algorithm that allow to mitigate such filtering effects. Experiments on simulated and real data on a 7 Tesla scanner show that the proposed ideas allow to drastically improve the overall image quality.
