An excellent primer on medical imaging for all members of the medical profession . . . including non-radiological specialists. It is technically solid and filled with diagrams and clinical images illustrating important points, but it is also easily readable . . . So many outstanding chapters . . . The book uses little mathematics beyond simple algebra [and] presents complex ideas in very understandable terms." —Melvin E. Clouse, MD, Vice Chairman Emeritus, Department of Radiology, Beth Israel Deaconess Medical Center and Deaconess Professor of Radiology, Harvard Medical School A well-known medical physicist and author, an interventional radiologist, and an emergency room physician with no special training in radiology have collaborated to write, in the language familiar to physicians, an introduction to the technology and clinical applications of medical imaging. It is intentionally brief and not overly detailed, intended to help clinicians with very little free time rapidly gain enough command of the critically important imaging tools of their trade to be able to discuss them confidently with medical and technical colleagues; to explain the general ideas accurately to students, nurses, and technologists; and to describe them effectively to concerned patients and loved ones. Chapter coverage includes: Introduction: Dr. Doe's Headaches Sketches of the Standard Imaging Modalities Image Quality and Dose Creating Subject Contrast in the Primary X-Ray Image Twentieth-Century (Analog) Radiography and Fluoroscopy Radiation Dose and Radiogenic Cancer Risk Twenty-First-Century (Digital) Imaging Digital Planar Imaging Computed Tomography Nuclear Medicine (Including SPECT and PET) Diagnostic Ultrasound (Including Doppler) MRI in One Dimension and with No Relaxation Mapping T1 and T2 Proton Spin Relaxation in 3D Evolving and Experimental Modalities
Although, within neurosonology, study of both the extracranial and the intracranial circulation began at least 15 years ago, it is only in recent years that ultrasound evaluation of cerebral veins and cerebral venous hemodynamics has attracted wider attention. Nevertheless, the huge variability in venous outflow pathways in normal subjects means that the potential usefulness of this examination is still often neglected. This atlas provides concise descriptions of the main normal and pathological ultrasound features of the cerebral venous circulation for neurosonologists and clinicians. It is designed as a practical tool that will be of assistance in everyday practice in the ultrasound lab and will improve the knowledge of sonologists and the reliability of venous ultrasound studies. The multimedia format, with detailed images, explanatory videos, and short, targeted descriptions, ensures that information is clearly conveyed and that users will become fully acquainted with the variability of normal findings of venous examinations. The atlas will be of value both to trainees in this field of ultrasound and to neurosonologists who are beginning to perform venous examinations in addition to arterial extra- and intracranial examinations.
Complex Finsler metrics appear naturally in complex analysis. To develop new tools in this area, the book provides a graduate-level introduction to differential geometry of complex Finsler metrics. After reviewing real Finsler geometry stressing global results, complex Finsler geometry is presented introducing connections, Kählerianity, geodesics, curvature. Finally global geometry and complex Monge-Ampère equations are discussed for Finsler manifolds with constant holomorphic curvature, which are important in geometric function theory. Following E. Cartan, S.S. Chern and S. Kobayashi, the global approach carries the full strength of hermitian geometry of vector bundles avoiding cumbersome computations, and thus fosters applications in other fields.
