PURPOSE Magnetic Particle Imaging (MPI) is a preclinical imaging technique capable of visualizing the spatio-temporal distribution of magnetic nanoparticles. The image reconstruction of this fast and dynamic process relies on efficiently solving an ill-posed inverse problem. Current approaches to reconstruct the tracer concentration from its measurements are either adapted to image characteristics of MPI but suffer from higher computational complexity and slower convergence or are fast but lack… Expand

Deep image prior for 3D magnetic particle imaging: A quantitative comparison of regularization techniques on Open MPI dataset
A novel reconstruction approach based on a deep image prior, which builds on representing the solution by a deep neural network is investigated, which compares quantitatively in terms of peak signal-to-noise ratios and structural similarity indices on the publicly available Open MPI dataset. Expand
Fast MPI reconstruction with non-smooth priors by stochastic optimization and data-driven splitting
Stochastic primal-dual hybrid gradient method is proposed to use to gain more flexibility concerning the choice of data fitting term and regularization, respectively, and still obtain an algorithm which is at least as fast as Kaczmarz method. Expand


Edge Preserving and Noise Reducing Reconstruction for Magnetic Particle Imaging
This work develops an efficient edge preserving and noise reducing reconstruction method for MPI and proposes to use the nonnegative fused lasso model, and devise a discretization that is adapted to the acquisition geometry of the preclinical MPI scanner considered in this work. Expand
Enhanced reconstruction in magnetic particle imaging by whitening and randomized SVD approximation.
This work revisits two issues in the numerical reconstruction in MPI in the lens of inverse theory, and proposes two algorithmic tricks, i.e. a whitening procedure to incorporate the noise statistics and accelerating Kaczmarz iteration via randomized SVD. Expand
Weighted iterative reconstruction for magnetic particle imaging.
The quality of the least-squares solution can be improved by incorporating a weighting matrix using the reciprocal of the matrix-row energy as weights and this weighting strategy in combination with the conjugate gradient method improves the image quality and substantially shortens the reconstruction time.

Comparison of System-Matrix-Based and Projection-Based Reconstructions for Field Free Line Magnetic Particle Imaging
In magnetic particle imaging (MPI), system sensitivity can be enhanced by scanning the sample along a field free line (FFL) instead of a field free point (FFP). FFL MPI data can then be processed viaExpand
Hybrid system calibration for multidimensional magnetic particle imaging.
In this work, the system matrix is determined by a hybrid approach and a new approach is introduced to address the background signal in image reconstruction, showing that this approach reduces artefacts in the reconstructed images. Expand
