Available in PDF, EPUB and Kindle. Book excerpt: The benefit of a medical imaging examination in terms of its ability to yield an accurate diagnosis depends on the quality of both the image and the image interpretation. During the past half century, nuclear medicine has grown tremendously due to advances in image detector systems and computer technology. However, conventional nuclear imaging systems still suffer from relatively low detection efficiency thereby affecting the spatial resolution of the system. Coded Aperture imaging is a technique that offers improved detection efficiency. This technique is discussed in this thesis. This technique offers improved photon-collection efficiency over the collimator systems commonly used with high-energy radiation and consequently offers the possibility of improved spatial resolution and contrast. The aperture chosen for this study is the annulus, due to its advantages which will be discussed in the later chapters. We also present the image collection and processing technique and finally a comparison of the collimator systems with the annular technique. Qualitative comparisons were made by visually inspecting the images obtained by the two techniques while quantitative comparisons were made by statistically testing their modulation transfer functions for significant differences. Both of the comparisons indicated that the annular technique was successful and gave images with increased spatial resolution and contrast.

Available in PDF, EPUB and Kindle. Book excerpt: This publication is a compendium of physical principles, system descriptions, instrument quality assurance, and clinical applications of extant tomographic methods in nuclear medicine. Written by an expert in this pertinent field, each chapter deals with the topics in a comprehensive fashion to provide a ready reference of all the work done on the subject and an estimate of the future utilization. Descriptions of methods available to nuclear medicine for tomographic viewing include positron emission, single photon emission, and planar tomography. This is an excellent resource volume of general applicability for nuclear medicine physicians, nuclear medicine scientists, and researchers in organ imaging and processing techniques.

Download or read book Nuclear Medicine Ultrasonics and Thermography written by Sol Nudelman and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 503 pages. Available in PDF, EPUB and Kindle. Book excerpt: The material in this volume was prepared and collected over the past four years with the growing realization that a technical revolution was in progress for diagnostic medicine. It became clear that for the wide variety of imaging instruments and methods finding their way into applications for research and clinical medicine, there was a scarcity of reference and text books for the scientist and engineer beginning in the field. Thus what began as a relatively small project for a single volume has grown into certainly two and probably three volumes to adequately cover the field. This first volume is expected to be followed within a few months by a second volume, dealing with diagnostic radiology, and within a year by a third volume, covering most other aspects of medicine that utilize spectra from the ultraviolet through the visible into the near-infrared. The chapters in this book are divided into three groups. The first group deals with nuclear medicine and includes Chapters 1-8. These chapters are arranged to begin with a broad introduction to the subject (Chapter 1) followed by a sequence of four chapters (Chapters 2-5) that provide an in-depth review of the imaging instrumentation developed for the field. Chapter 6 deals with "evaluation" of imaging device per formance, while Chapters 7 and 8 discuss two areas of considerable re search activity.

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.

Download or read book Applications of Holography and Optical Data Processing written by E. Marom and published by Elsevier. This book was released on 2013-10-22 with total page 741 pages. Available in PDF, EPUB and Kindle. Book excerpt: Applications of Holography and Optical Data Processing contains the proceedings of the International Conference on Applications of Holography and Optical Data Processing, held in Jerusalem in August 1976. The conference is attended by eminent scientists in the field of optics, characterized by high-level scientific presentations and discussions. The collection is a representation of research on the cutting edge of applied and theoretical optics. The four-day meeting covers topics on holographic applications in medicine, interferometry, display, storage, and retrieval, as well as image processing, measuring techniques, spectroscopy, and recording materials and devices. The participants of the conference believe in the promising future of research on Optical Data Processing as long as techniques are complemented by electronic support. The book will be of value to electronics engineers, technicians, computer scientists, and computer engineers.
