Efficient Joint Estimation of Tracer Distribution and Background Signals in Magnetic Particle Imaging using a Dictionary Approach

1 code implementation • 10 Jun 2020 • Tobias Knopp, Mirco Grosser, Matthias Graeser, Timo Gerkmann, Martin Möddel

Background signals are a primary source of artifacts in magnetic particle imaging and limit the sensitivity of the method since background signals are often not precisely known and vary over time.

3d-SMRnet: Achieving a new quality of MPI system matrix recovery by deep learning

1 code implementation • 8 May 2019 • Ivo Matteo Baltruschat, Patryk Szwargulski, Florian Griese, Mirco Grosser, René Werner, Tobias Knopp

In this work, we propose a novel framework with a 3d-System Matrix Recovery Network and demonstrate it to recover a 3d system matrix with a subsampling factor of 64 in less than one minute and to outperform CS in terms of system matrix quality, reconstructed image quality, and processing time.
