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.

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.

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.

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.

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.

3D Printing for Tissue Engineering and Regenerative Medicine by Murat Guvendiren ,Vahid Serpooshan Pdf

Three-dimensional (3D) printing enables the fabrication of tissue-engineered constructs and devices from a patient’s own medical data, leading to the creation of anatomically matched and patient-specific constructs. There is a growing interest in applying 3D printing technologies in the fields of tissue engineering and regenerative medicine. The main printing methods include extrusion-based, vat photopolymerization, droplet-based, and powder-based printing. A variety of materials have been used for printing, from metal alloys and ceramics to polymers and elastomers as well as from hydrogels to extracellular matrix proteins. More recently, bioprinting, a subcategory of 3D printing, has enabled the precise assembly of cell-laden biomaterials (i.e., bioinks) for the construction of complex 3D functional living tissues or artificial organs. In this Special Issue, we aim to capture state-of-the-art research papers and the most current review papers focusing on 3D printing for tissue engineering and regenerative medicine. In particular, we seek novel studies on the development of 3D printing and bioprinting approaches, developing printable materials (inks and bioinks), and utilizing 3D-printed scaffolds for tissue engineering and regenerative medicine applications. These applications are not limited to but include scaffolds for in vivo tissue regeneration and tissue analogues for in vitro disease modeling and/or drug screening.
