Available in PDF, EPUB and Kindle. Book excerpt: A Coded Aperature Imaging System (CAIS) has been developed at Sandia National Laboratories to image the motion of nuclear fuel rods undergoing tests simulating accident conditions within a liquid metal fast breeder reactor. The tests require that the motion of the test fuel be monitored while it is immersed in a liquid sodium coolant precluding the use of normal optical means of imaging. However, using the fission gamma rays emitted by the fuel itself and coded aperture techniques, images with 1.5 mm radial and 5 mm axial resolution have been attained. Using an electro-optical detection system coupled to a high speed motion picture camera a time resolution of one millisecond can be achieved. This paper will discuss the application of coded aperture imaging to the problem, including the design of the one-dimensional Fresnel zone plate apertures used and the special problems arising from the reactor environment and use of high energy gamma ray photons to form the coded image. Also to be discussed will be the reconstruction techniques employed and the effect of various noise sources on system performance. Finally, some experimental results obtained using the system will be presented.
Download or read book Radiological Imaging written by Harrison H. Barrett and published by Elsevier. This book was released on 2012-12-02 with total page 709 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radiological Imaging: The Theory of Image Formation, Detection, and Processing is intended to prepare the student to do research in radiological imaging, to teach general image science within a radiographic context, and to help the student gain fluency with the essential analytical tools of linear systems theory and the theory of stochastic processes that are applicable to any imaging system. The book contains chapters devoted to the discussion of linear systems, Poisson processes, analysis of radiographic systems, radiographic image detectors, and the various aspects of three-dimensional or tomographic imaging. Computed tomography, psychophysics, and scattered radiation and its effect on image are also elucidated. Radiology technicians will find the book very invaluable.

Available in PDF, EPUB and Kindle. Book excerpt: This handbook offers insights into how science (physical, natural and social) and technology can support new developments to manage the complexity resident within the threat and risk landscape. The security landscape can be described as dynamic and complex stemming from the emerging threats and risks that are both persistent and transborder. Globalization, climate change, terrorism, transnational crime can have significant societal impact and forces one to re-evaluate what ‘national security’ means. Recent global events such as mass migration, terrorist acts, pandemics and cyber threats highlight the inherent vulnerabilities in our current security posture. As an interdisciplinary body of work, the Handbook of Security Science captures concepts, theories and security science applications, thereby providing a survey of current and emerging trends in security. Through an evidence-based approach, the collection of chapters in the book delivers insightful and comprehensive articulation of the problem and solution space associated with the complex security landscape. In so doing the Handbook of Security Science introduces scientific tools and methodologies to inform security management, risk and resilience decision support systems; insights supporting design of security solutions; approaches to threat, risk and vulnerability analysis; articulation of advanced cyber security solutions; and current developments with respect to integrated computational and analytical solutions that increase our understanding of security physical, social, economic, and technological interrelationships and problem space.
