Traveling Wave Magnetic Particle Imaging [PDF]

IEEE Transactions on Medical Imaging, 2014
Most 3-D magnetic particle imaging (MPI) scanners currently use permanent magnets to create the strong gradient field required for high resolution MPI. However, using permanent magnets limits the field of view (FOV) due to the large amount of energy required to move the field free point (FFP) from the center of the scanner.

Towards quantitative magnetic particle imaging: A comparison with magnetic particle spectroscopy

AIP Advances, 2018
Magnetic Particle Imaging (MPI) is a quantitative imaging modality with promising features for several biomedical applications. Here, we study quantitatively the raw data obtained during MPI measurements.

Bimodal Interventional Instrument Markers for Magnetic Particle Imaging and Magnetic Resonance Imaging—A Proof-of-Concept Study

Nanomaterials, 2022
The purpose of this work was to develop instrument markers that are visible in both magnetic particle imaging (MPI) and magnetic resonance imaging (MRI). The instrument markers were based on two different magnetic nanoparticle types (synthesized in-house

Trivariate polynomial approximation on Lissajous curves [PDF]

, 2015
We study Lissajous curves in the 3-cube, that generate algebraic cubature formulas on a special family of rank-1 Chebyshev lattices. These formulas are used to construct trivariate hyperinterpolation polynomials via a single 1-d Fast Chebyshev Transform (

The sensitivity of magnetic particle imaging and fluorine-19 magnetic resonance imaging for cell tracking

Scientific Reports, 2021
Magnetic particle imaging (MPI) and fluorine-19 (19F) MRI produce images which allow for quantification of labeled cells. MPI is an emerging instrument for cell tracking, which is expected to have superior sensitivity compared to 19F MRI.

Hyperpolarized Long-T1 Silicon Nanoparticles for Magnetic Resonance Imaging [PDF]

, 2009
Silicon nanoparticles are experimentally investigated as a potential hyperpolarized, targetable MRI imaging agent. Nuclear T_1 times at room temperature for a variety of Si nanoparticles are found to be remarkably long (10^2 to 10^4 s) - roughly ...

Projection Reconstruction Magnetic Particle Imaging [PDF]

IEEE Transactions on Medical Imaging, 2013
We acquire the first experimental 3-D tomographic images with magnetic particle imaging (MPI) using projection reconstruction methodology, which is similar to algorithms employed in X-ray computed tomography. The primary advantage of projection reconstruction methods is an order of magnitude increase in signal-to-noise ratio (SNR) due to averaging.

Clinical magnetic hyperthermia requires integrated magnetic particle imaging [PDF]

WIREs Nanomedicine and Nanobiotechnology, 2022
AbstractMagnetic nanomaterials that respond to clinical magnetic devices have significant potential as cancer nanotheranostics. The complexities of their physics, however, introduce challenges for these applications. Hyperthermia is a heat‐based cancer therapy that improves treatment outcomes and patient survival when controlled energy delivery is ...
