Magnetic particle imaging (MPI) is a tomographic imaging technique for determining the spatial distribution of superparamagnetic nanoparticles. Current MPI systems are capable of imaging iron masses over a wide dynamic range of more than four orders of magnitude. In theory, this range could be further increased using adaptive amplifiers, which prevent signal clipping. While this applies to a single sample, the dynamic range is severely limited if several samples with different concentrations or… 
System Matrix Based Reconstruction for Pulsed Sequences in Magnetic Particle Imaging
Improving resolution and sensitivity will widen possible medical applications of magnetic particle imaging. Pulsed excitation promises such benefits, at the cost of more complex hardware solutions
The sensitivity of magnetic particle imaging and fluorine-19 magnetic resonance imaging for cell tracking
MPI has the potential to be more sensitive than 19F MRI for cell tracking and is attributed to the effect of cell dispersion among other factors, which are described.
Magnetic Particle Imaging is a sensitive in vivo imaging modality for the quantification of dendritic cell migration
This study demonstrates the clear advantage of MPI to detect and quantify cells in vivo, bridging the gap left by cellular MRI, and all other in vivo imaging modalities, and opening the door for quantitative imaging of cellular immunotherapies.
Magnetic Particle Imaging Is a Sensitive In Vivo Imaging Modality for the Detection of Dendritic Cell Migration
The first study using MPI to detect and track DC injected into the footpads of C57BL/6 mice migrating to the popliteal lymph nodes (pLNs) is described, bringing attention to the issue of resolving unequal signals within close proximity.
Magnetic nanoparticles in theranostic applications

Sensitivity Enhancement in Magnetic Particle Imaging by Background Subtraction
The background signals in raw data that were measured without any SPIOs in the scanner tube are examined and it is shown that a background subtraction in combination with a frequency cutoff for the dynamic part of the background signal lowers the detection limit for SPI up to a factor of ten.
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.
Towards accurate modeling of the multidimensional magnetic particle imaging physics
The image reconstruction problem of the tomographic imaging technique magnetic particle imaging (MPI) requires the solution of a linear inverse problem. One prerequisite for this task is that the
