Using numerous mathematical and numerical techniques of diffraction theory, Waves in Focal Regions: Propagation, Diffraction and Focusing of Light, Sound and Water Waves provides a full and richly illustrated description of waves in focal regions. Unlike most books, the author treats electromagnetic, acoustic, and water waves in one comprehensive volume. After an introductory section, the book describes approximate diffraction theories and efficient numerical methods to study the focusing of various kinds of waves. It then covers the physical interpretation of the theories, their accuracy, and the computational savings obtained, emphasizing uniform asymptotic results that remain valid in the vicinity of shadow boundaries and caustics. The next part deals with the focusing of scalar waves, including thorough theoretical analyses and detailed contour maps of diffraction patterns in focal regions for a variety of different system parameters, such as f-number, Frensel number, aperture shape, amplitude distribution, and wavefront aberration. The author proceeds to explore the diffraction and focusing of electromagnetic waves. First solutions are derived for fields radiated by sources, reflected and refracted at plane interfaces, or diffracted by apertures in plane screens, and then these solutions are applied to study the focusing in homogeneous media and through a plane dielectric interface. In both cases, the author includes many computed results of the electromagnetic field distribution near focus. Presenting both theoretical and experimental results, the following part examines the focusing of sound and water waves by means of zone-plate lenses. The book concludes with a detailed study of the diffraction and focusing of water waves and a comparison of the results of both linear and nonlinear theories with those of experiments.

Focal Points in Negotiation is the first work of its kind to analyze the use of focal points beyond the controlled setting of the laboratory or the stylized context of mathematical game theory, in the real world of negotiation. It demonstrates that there are many more ways focal points influence real life situations than the specific, predetermined roles ascribed to them by game theory and rational choice. The book establishes this by identifying the numerous different, often decisive, modes in which focal points function in the various phases of complex negotiations. In doing so, it also demonstrates the necessity of a thorough understanding of focal points for mediators, negotiators, and others. A scholarly work in nature, Focal Points in Negotiation is also suitable for use in the classroom and accessible for a multidisciplinary audience.

Few fields of medicine have witnessed such impressive progress as the diagnosis and treatment of liver tumors. Advances in imaging technology, the development of novel contrast agents, and the introduction of optimized scanning protocols have greatly facilitated the non-invasive detection and characterization of focal liver lesions. Furthermore, image-guided techniques for percutaneous tumor ablation have become an accepted alternative treatment for patients with inoperable liver cancer. This book provides a comprehensive and up-to-date overview of the role of diagnostic and interventional radiology in respect of liver tumors. The volume moves from background sections on methodology and segmental liver anatomy to the main sections on the diagnosis of benign and malignant liver lesions. An integrated approach, focused on the correlation of ultrasound, CT, and MR imaging findings, is presented. Finally, a full section describes the principles, methods, and results of percutaneous tumor ablation techniques.

Prostate cancer is the commonest cancer in men. Current treatments include surgery to remove the whole prostate or radiotherapy of the whole prostate. These radical treatments can treat the cancer effectively but often cause unwanted side effects. Meanwhile widespread screening with prostate-specific antigen has led to an increased diagnosis of localised prostate cancer; at the same time, widespread use of abdominal imaging has led to increased detection of renal masses. In response to demand for improved outcomes with reduced side effects, focal therapy has emerged as an important procedure in managing both prostate and renal cancers. It targets individual areas of cancer, reducing unwanted side effects and the amount of damage to collateral tissue. This new method of treatment has major advantages: it involves less radiation, the removal of less tissue and less time spent in hospital. Handbook of Focal Therapy for Prostate and Renal Cancer provides a comprehensive, timely review of targeted ablation methods to treat prostate and renal cancers. It describes the most effective techniques in current practice, with discussion of the selection criteria, ablation technologies and their limitations, and advice on the management of common side effects. The book opens with a summary of the principles of prostate and renal cancer treatment and the mechanisms of focal therapy. Separate sections on prostate and kidney follow, covering the role of focal therapy, side effects and their treatment and follow-up after targeted ablation. Written in a practical, clinically-oriented style, Handbook of Focal Therapy for Prostate and Renal Cancer is the ideal reference for urologists, radiologists and radiation oncologists wishing to employ the latest focal therapy techniques in the care of their patients.
