Hands-free Reconstruction for MPI

Main Article Content


In iterative system-matrix-based reconstruction in Magnetic Particle Imaging, three major parameters control
the amount of regularization. Finding the right choice for these parameters is commonly done by user input and
requires time and experience. We propose a method that enables automatic reconstruction and achieves good
results on a measured concentration series.
