| physics of ct scan: Mathematics and Physics of Emerging Biomedical Imaging Committee on the Mathematics and Physics of Emerging Dynamic Biomedical Imaging, Commission on Physical Sciences, Mathematics, and Applications, Division on Engineering and Physical Sciences, National Research Council, 1996-03-13 This cross-disciplinary book documents the key research challenges in the mathematical sciences and physics that could enable the economical development of novel biomedical imaging devices. It is hoped that the infusion of new insights from mathematical scientists and physicists will accelerate progress in imaging. Incorporating input from dozens of biomedical researchers who described what they perceived as key open problems of imaging that are amenable to attack by mathematical scientists and physicists, this book introduces the frontiers of biomedical imaging, especially the imaging of dynamic physiological functions, to the educated nonspecialist. Ten imaging modalities are covered, from the well-established (e.g., CAT scanning, MRI) to the more speculative (e.g., electrical and magnetic source imaging). For each modality, mathematics and physics research challenges are identified and a short list of suggested reading offered. Two additional chapters offer visions of the next generation of surgical and interventional techniques and of image processing. A final chapter provides an overview of mathematical issues that cut across the various modalities. |
| physics of ct scan: CT Imaging Alexander C. Mamourian, Harold I. Litt, 2013-03-14 After reading this book, imagers and CT technologists should better understand the capabilities of modern multidector CT scanners. Imagers and technologists must understand how their scanners operate in order to take advantage of new capabilities for optimizing protocols that minimize patient dose. In addition, the reader will be better prepared to recognize the pitfalls and artifacts that appear on CT imaging. Some of these are unfamiliar to most imagers and are the product of the large detector arrays offered on new CT scanners. |

| physics of ct scan: Industrial X-Ray Computed Tomography Simone Carmignato, Wim Dewulf, Richard Leach, 2017-10-18 X-ray computed tomography has been used for several decades as a tool for measuring the three-dimensional geometry of the internal organs in medicine. However, in recent years, we have seen a move in manufacturing industries for the use of X-ray computed tomography; first to give qualitative information about the internal geometry and defects in a component, and more recently, as a fully-quantitative technique for dimensional and materials analysis. This trend is primarily due to the ability of X-ray computed tomography to give a high-density and multi-scale representation of both the external and internal geometry of a component, in a non-destructive, non-contact and relatively fast way. But, due to the complexity of X-ray computed tomography, there are remaining metrological issues to solve and the specification standards are still under development. This book will act as a one-stop-shop resource for students and users of X-ray computed tomography in both academia and industry. It presents the fundamental principles of the technique, detailed descriptions of the various components (hardware and software), current developments in calibration and performance verification and a wealth of example applications. The book will also highlight where there is still work to do, in the perspective that X-ray computed tomography will be an essential part of Industry 4.0. |

| physics of ct scan: The Essential Physics of Medical Imaging Jerrold T. Bushberg, J. Anthony Seibert, Edwin M. Leidholdt, John M. Boone, 2011-12-28 This renowned work is derived from the authors' acclaimed national review course (“Physics of Medical Imaging) at the University of California-Davis for radiology residents. The text is a guide to the fundamental principles of medical imaging physics, radiation protection and radiation biology, with complex topics presented in the clear and concise manner and style for which these authors are known. Coverage includes the production, characteristics and interactions of ionizing radiation used in medical imaging and the imaging modalities in which they are used, including radiography, mammography, fluoroscopy, computed tomography and nuclear medicine. Special attention is paid to optimizing patient dose in each of these modalities. Sections of the book address topics common to all forms of diagnostic imaging, including image quality and medical informatics as well as the non-ionizing medical imaging modalities of MRI and ultrasound. The basic science important to nuclear imaging, including the nature and production of radioactivity, internal dosimetry and radiation detection and measurement, are presented clearly and concisely. Current concepts in the fields of radiation biology and radiation protection relevant to medical imaging, and a number of helpful appendices complete this comprehensive textbook. The text is enhanced by numerous full color charts, tables, images and superb illustrations that reinforce central concepts. The book is ideal for medical imaging professionals, and teachers and students in medical physics and biomedical engineering. Radiology residents will find this text especially useful in bolstering their understanding of imaging physics and related topics prior to board exams. |
| physics of ct scan: Principles of Computerized Tomographic Imaging Avinash C. Kak, Malcolm Slaney, 1988-01-01 Principles of Computerized Tomographic Imaging provides a comprehensive, tutorial-style introduction to the algorithms for reconstructing cross-sectional images from projection data and contains a complete overview of the engineering and signal processing algorithms necessary for tomographic imaging. In addition to the purely mathematical and algorithmic aspects of these algorithms, the book also discusses the artifacts caused by the nature of the various forms of energy sources that can be used for generating the projection data. Since the fundamental aspects of tomographic reconstruction algorithms have remained virtually the same since this book was originally published, it is just as useful today as it was in 1987. It explains, among other things, what happens when there is excessive noise in the projection data; when images are formed from insufficient projection data; and when refracting or diffracting energy sources are used for imaging. Audience: beginning graduate students or practitioners wishing to see the development of the algorithm from the ground up, as well as anyone interested in cross-sectional imaging for a wide variety of applications. |
| physics of ct scan: Computed Tomography Jiang Hsieh, 2009-01-01 X-ray computed tomography (CT) continues to experience rapid growth, both in basic technology and new clinical applications. Seven years after its first edition, Computed Tomography: Principles, Design, Artifacts, and Recent Advancements, Second Edition, provides an overview of the evolution of CT, the mathematical and physical aspects of the technology, and the fundamentals of image reconstruction algorithms.

| physics of ct scan: Cardiac PET and PET/CT Imaging Marcello F. Di Carli, Martin J. Lipton, 2007-12-05 When the history of medicine in the latter half of the twentieth century is written, the advances in cardiovascular diagnosis, therapy, and prevention will stand out as one of the most important achievements. Although the age-corrected death rate secondary to coronary artery disease has declined substantially in industri- ized nations during this period, the prevalence of these conditions remains stubbornly high because of the aging of the population. Importantly, the incidence of coronary events and of one of their most important sequelae—heart failure—is rising ala- ingly in the developing world. When viewed from a global perspective, cardiovascular disease is assuming a progressively greater importance, and it is estimated that by 2025 it will be, for the ? rst time in human history, the most common cause of death. Clearly, rather than resting on the laurels of our achievements, an intensi? cation of the battle against cardiovascular disease must now be undertaken. Cardiovascular imaging will, without question, play a critical role in this battle. The appropriate sel- tion of therapeutic measures, be they pharmacologic, catheter-based, surgical, alte- tions in lifestyles, or some combination of these, depends on accurate assessments of both cardiac structure and function. Increasingly, the changes that dictate mana- ment are quite subtle and require a level of precision that was not available to cli- cians heretofore. |
