Magnetic-field measurement and simulation of a field-free line magnetic-particle scanner

Measurement and simulation of magnetic field strenght in the nano magnetic abrasive finishing process

Magnetic abrasive finishing can be classified as a non-traditional super finishing method for finishing surfaces with different shapes and working materials like flat plates, shafts, bearings parts, screws, tubes and many other mechanical parts that need good surface finishing properties. MAF is effective in polishing, cleaning, deburring and burnishing metal parts. The most important parameter...

A simulation study on image reconstruction in magnetic particle imaging with field-free-line encoding

Short title: Simulation studies on image reconstruction in MPI Abstract The purpose of this study was to present image reconstruction methods for magnetic particle imaging (MPI) with a field-free-line (FFL) encoding scheme and to propose the use of the maximum likelihood-expectation maximization (ML-EM) algorithm for improving the image quality of MPI. The feasibility of these methods was inves...

Reconstruction of Solar Coronal Linear Force-Free Magnetic Field

Design Optimisation of an Field Free Point Magnetic Particle Imaging Scanner

Introduction Magnetic Particle Imaging (MPI) is a new imaging technology aimed at the imaging of a tracer in the human body. First published in 2005 [1], the number of scanner prototypes is growing and there is always more room for optimisation in each new scanner design. The imaging principle is based on the non-linear magnetisation of magnetic nanoparticles. Placed in a magnetic field they ca...

Efficient generation of a magnetic field-free line.

PURPOSE Signal encoding in magnetic particle imaging (MPI) is achieved by moving a field-free point (FFP) through the region of interest. One way to increase the sensitivity of the method is to scan the region of interest with a field-free line (FFL) instead of the FFP. Recently, the first feasible FFL coil setup was introduced. The purpose of this article is to improve the efficiency of the FF...
