Magnetomotive Dynamics of Magnetic Particles for Optical Imaging Contrast and Elastography
Magneto-Optical Imaging
Author: Tom H. JohansenPublisher: Springer Science & Business Media
ISBN: 9400710070
Category : Science
Languages : en
Pages : 356
Book Description
Magneto-Optical Imaging has developed rapidly over the last decade to emerge as a leading technique to directly visualise the static and dynamic magnetic behaviour of materials, capable of following magnetic processes on the scale of centimeters to sub-microns and at timescales from hours to nanoseconds. The images are direct, real-time, and give space-resolved information, such as ultrafast magnetic processes and revealing the motion of individual vortices in superconductors. The book is a fully up-to-date report of the present status of the technique.
Optical Techniques in Regenerative Medicine
Author: Stephen P. MorganPublisher: Taylor & Francis
ISBN: 1439854963
Category : Medical
Languages : en
Pages : 445
Book Description
In regenerative medicine, tissue engineers largely rely on destructive and time-consuming techniques that do not allow in situ and spatial monitoring of tissue growth. Furthermore, once the therapy is implanted in the patient, clinicians are often unable to monitor what is happening in the body. To tackle these barriers, optical techniques have bee

Tissue Elasticity Imaging
Author: S. Kaisar AlamPublisher: Elsevier
ISBN: 0128096616
Category : Science
Languages : en
Pages : 258
Book Description
Tissue Elasticity Imaging: Volume One, Theory and Methods offers an extensive treatment of the fundamentals and applications of this groundbreaking diagnostic modality. The book introduces elasticity imaging, its history, the fundamental physics, and the different elasticity imaging methods, along with their implementation details, problems and artefacts. It is an essential resource for all researchers and practitioners interested in any elasticity imaging modality. As many diseases, including cancers, alter tissue mechanical properties, it is not always possible for conventional methods to detect changes, but with elasticity images that are produced by slow tissue deformation or low-frequency vibration, these changes can be displayed. Offers the first comprehensive reference on elasticity imaging Discusses the fundamentals of technology and their limitations and solutions, along with advanced methods and future directions Addresses the technologies and applications useful to both researchers and clinical practitioners Includes an online reference section regularly updated with advances in technology and applications
On the Dynamics of Magnetic Fluids in Magnetic Resonance Imaging

Pages : 233
Book Description
The hydrodynamics of magnetic fluids, often termed ferrofluids, has been an active area of research since the mid 1960s. However, it is only in the past twenty years that these fluids have begun to be used in magnetic resonance imaging (MRI) where they have found application as contrast agents, improving the contrast to noise ratio of the received MR intensity. The major goal of this work was to assess the feasibility of modulating the signal intensity in MRI in regions near superparamagnetic iron oxide contrast agents by applying a rotating magnetic field. Analytical study and numerical simulations of the effects of such a rotating magnetic field are presented. Simulated variations in fluid magnetization are achieved by changing the frequency of the rotating magnetic field. A linearization of the equilibrium magnetization Langevin relation results in a small signal magnetic susceptibility tensor that can be used to influence fluid flow. The feasibility of the approach under the real-life constraints of MR imaging are assessed. Also examined is the potential for coupling changes in magnetization due to rotating fields with hypothermia treatment of cancerous tissue. In addition to theoretical and simulated analysis, considerable experimental work was undertaken at the MRI systems of the HST Athinoula A. Martinos Center for Biomedical Imaging at Massachusetts General Hospital, Charlestown, Massachusetts. This work evaluated the passive behavior of both commercial ferrofluids and MRI contrast agents. The ability of MRI to serve as a highly accurate indicator of the fluid's physical and magnetic properties is shown. The thesis represents the first investigation into the use of the hydrodynamic properties of magnetic fluid in the presence of a rotating field as a mechanism for contrast in MRI. The results show the possibility of varying MR image intensity under careful selection of field conditions.
Approximate Analytical Methods for Solving Ordinary Differential Equations
Author: T.S.L RadhikaPublisher: CRC Press
ISBN: 1466588136
Category : Mathematics
Languages : en
Pages : 584
Book Description
Approximate Analytical Methods for Solving Ordinary Differential Equations (ODEs) is the first book to present all of the available approximate methods for solving ODEs, eliminating the need to wade through multiple books and articles. It covers both well-established techniques and recently developed procedures, including the classical series solution method, diverse perturbation methods, pioneering asymptotic methods, and the latest homotopy methods. The book is suitable not only for mathematicians and engineers but also for biologists, physicists, and economists. It gives a complete description of the methods without going deep into rigorous mathematical aspects. Detailed examples illustrate the application of the methods to solve real-world problems. The authors introduce the classical power series method for solving differential equations before moving on to asymptotic methods. They next show how perturbation methods are used to understand physical phenomena whose mathematical formulation involves a perturbation parameter and explain how the multiple-scale technique solves problems whose solution cannot be completely described on a single timescale. They then describe the Wentzel, Kramers, and Brillown (WKB) method that helps solve both problems that oscillate rapidly and problems that have a sudden change in the behavior of the solution function at a point in the interval. The book concludes with recent nonperturbation methods that provide solutions to a much wider class of problems and recent analytical methods based on the concept of homotopy of topology.
