Implementation of a Magnetic Particle Imaging System for a Dynamic Field Free Line by Klaas Bente Pdf

A new tomographic imaging modality called magnetic particle imaging (MPI) has been proposed in 2005. Using the non-linear magnetization curve of specific nanoparticles, a detectable signal proportional to the concentration of these particles can be generated. For medical imaging the tracer material can be injected into the blood system. Due to fast image acquisition, not only morphological, but also functional imaging is possible. The feasibility of medical imaging with this technique could be demonstrated at real time imaging of a beating mouse heart. Spatial encoding is provided by superimposing dedicated external magnetic fields. For the resulting shape of this field a field free line has been proposed. This work presents the implementation of the MPI system with a discretely rotatable and dynamically translatable field free line.

Field Free Line Magnetic Particle Imaging by Marlitt Erbe Pdf

Marlitt Erbe provides a detailed introduction into the young research field of Magnetic Particle Imaging (MPI) and field free line (FFL) imaging in particular. She derives a mathematical description of magnetic field generation for FFL imaging in MPI. To substantiate the simulation studies on magnetic FFL generation with a proof-of-concept, the author introduces the FFL field demonstrator, which provides the world’s first experimentally generated rotated and translated magnetic FFL field complying with the requirements for FFL reconstruction. Furthermore, she proposes a scanner design of considerably enhanced magnetic field quality and efficiency. The author discusses the influence of magnetic field quality optimization on the image quality achieved using efficient Radon-based reconstruction methods, which arise for a line detection scheme and based on this optimized design, presents a dynamic FFL scanner assembly.

Magnetic Particle Imaging by Tobias Knopp,Thorsten M. Buzug Pdf

This volume provides a comprehensive overview of recent developments in magnetic particle imaging (MPI), a novel imaging modality. Using various static and oscillating magnetic fields, and tracer materials made from iron oxide nanoparticles, MPI can perform background-free measurements of the particles’ local concentration. The method exploits the nonlinear remagnetization behavior of the particles and has the potential to surpass current methods for the detection of iron oxide in terms of sensitivity and spatiotemporal resolution. Starting from an introduction to the technology, the topics addressed include setting up an imaging device, assessment of image quality, development of new MPI tracer materials, and the first preclinical results. This is the first book to be published on magnetic particle imaging, and it will be an invaluable source of information for everyone with an interest in this exciting new modality.

Modeling, Simulation and Optimization of Fluid Dynamic Applications by Armin Iske,Thomas Rung Pdf

This book describes recent collaborations combining the expertise of applied mathematicians, engineers and geophysicists within a research training group (RTG) on "Modeling, Simulation and Optimization of Fluid Dynamic Applications”, funded by the Deutsche Forschungsgemeinschaft (DFG). The focus is on mathematical modeling, adaptive discretization, approximation strategies and shape optimization with PDEs. The balanced research program is based on the guiding principle that mathematics drives applications and is inspired by applications. With this leitmotif the RTG advances research in Modeling, Simulation and Optimization by an interdisciplinary approach, i.e., to stimulate fundamental education and research by highly complex applications and at the simultaneously transfer tailored mathematical methods to applied sciences. The reported research involves nine projects and addresses challenging fluid dynamic problems inspired by applied sciences, such as climate research & meteorology, energy, aerospace & marine engineering, or medicine. More fundamental research concerning analysis, approximation and numerics is also covered. The material represents a successful attempt to exchange research paradigms between different disciplines and thus displays a modern approach to basic research into scientifically and societally relevant contemporary problems.

Magnetic Particle Imaging by Thorsten M. Buzug,Jörn Borgert Pdf

Magnetic Particle Imaging (MPI) is a novel imaging modality. In MPI superparamagnetic iron oxide nanoparticles are used as tracer materials. The volume is the proceeding of the 2nd international workshop on magnetic particle imaging (IWMPI). The workshop aims at covering the status and recent developments of both, the instrumentation and the tracer material, as each of them is equally important in designing a well performing MPI. For instance, the current state of the art in magnetic coil design for MPI is discussed. With a new symmetrical arrangement of coils, a field-free line (FFL) can be produced that promises a significantly higher sensitivity compared with the standard arrangement for a FFP. Furthermore, the workshop aims at presenting results from phantom and pre-clinical studies.

Power-Loss Optimized Field-Free Line Generation for Magnetic Particle Imaging by Matthias Weber Pdf

Magnetic Particle Imaging (MPI) is a novel medical imaging technology that is able to acquire the distribution of superparamagnetic iron oxide nanoparticles in real-time with high spatial and temporal resolution. Spatial encoding is realized by a magnetic field configuration generating a field-free point (FFP). Therefore, the FFP is moved through the field of view (FOV). However, at low particle concentrations the signal-to-noise ratio (SNR) decreases and therefore image quality worsens. An enhanced encoding scheme uses instead of the FFP the concept of a field-free line (FFL), whereby a gain of sensitivity of one order of magnitude can be realized. Simulation studies approximate power consumption to a minimum and improve field homogeneity with the result that fast Radon-based reconstruction techniques are feasible. On the basis of these studies, this book describes the manufacturing of an optimized scanner topology realizing an excellent field quality with the help of customized curved rectangular coils. Furthermore, the power loss is efficiently minimized.

Scientific and Clinical Applications of Magnetic Carriers by Urs Häfeli,Wolfgang Schütt,Joachim Teller,Maciej Zborowski Pdf

The discovery of uniform latex particles by polymer chemists of the Dow Chemical Company nearly 50 years ago opened up new exciting fields for scientists and physicians and established many new biomedical applications. Many in vitro diagnostic tests such as the latex agglutination tests, analytical cell and phagocytosis tests have since become rou tine. They were all developed on the basis of small particles bound to biological active molecules and fluorescent and radioactive markers. Further developments are ongoing, with the focus now shifted to applications of polymer particles in the controlled and di rected transport of drugs in living systems. Four important factors make microspheres interesting for in vivo applications: First, biocompatible polymer particles can be used to transport known amounts of drug and re lease them in a controlled fashion. Second, particles can be made of materials which bio degrade in living organisms without doing any harm. Third, particles with modified surfaces are able to avoid rapid capture by the reticuloendothelial system and therefore en hance their blood circulation time. Fourth, combining particles with specific molecules may allow organ-directed targeting.

Evolving BCI Therapy by Denis Larrivee Pdf

As a strategic response to cognitive and CNS impairments, BCI is a theoretical outgrowth of several generations of endogenous devices for peripheral nerves, which have as a prime goal the direct replacement of lost neural function. In these earlier applications therapeutic intervention has been premised only on the restoration of signal generating capacity where nerve transmission is largely unidirectional and temporally sequenced. It is increasingly apparent, however, that the brain not only employs a very different type of syntax from that of peripheral nerves but also structures the semantic content of motor activity, fundamentally altering the conception of BCI as a therapeutic medium. The book presented here documents this change, proposing a multi-faceted strategy in which BCI therapy can restore the loss of multi-tiered, brain based motor function.
