A self-contained approach to DSP techniques and applications in radar imaging The processing of radar images, in general, consists of three major fields: Digital Signal Processing (DSP); antenna and radar operation; and algorithms used to process the radar images. This book brings together material from these different areas to allow readers to gain a thorough understanding of how radar images are processed. The book is divided into three main parts and covers: * DSP principles and signal characteristics in both analog and digital domains, advanced signal sampling, and interpolation techniques * Antenna theory (Maxwell equation, radiation field from dipole, and linear phased array), radar fundamentals, radar modulation, and target-detection techniques (continuous wave, pulsed Linear Frequency Modulation, and stepped Frequency Modulation) * Properties of radar images, algorithms used for radar image processing, simulation examples, and results of satellite image files processed by Range-Doppler and Stolt interpolation algorithms The book fully utilizes the computing and graphical capability of MATLAB? to display the signals at various processing stages in 3D and/or cross-sectional views. Additionally, the text is complemented with flowcharts and system block diagrams to aid in readers' comprehension. Digital Signal Processing Techniques and Applications in Radar Image Processing serves as an ideal textbook for graduate students and practicing engineers who wish to gain firsthand experience in applying DSP principles and technologies to radar imaging.
Unix Shell Programming is a tutorial aimed at helping Unix and Linux users get optimal performance out of their operating out of their operating system. It shows them how to take control of their systems and work efficiently by harnessing the power of the shell to solve common problems. The reader learns everything he or she needs to know to customize the way a Unix system responds. The vast majority of Unix users utilize the Korn shell or some variant of the Bourne shell, such as bash. Three are covered in the third edition of Unix Shell Programming. It begins with a generalized tutorial of Unix and tools and then moves into detailed coverage of shell programming. Topics covered include: regular expressions, the kernel and the utilities, command files, parameters, manipulating text filters, understanding and debugging shell scripts, creating and utilizing variables, tools, processes, and customizing the shell.
With a focus on the basic imaging principles of breast MRI rather than on mathematical equations, this book takes a practical approach to imaging protocols, which helps radiologists increase their diagnostic effectiveness. It walks the reader through the basics of MRI, making it especially accessible to beginners. From a detailed outline of equipment prerequisites for obtaining high quality breast MRI to instructions on how to optimize image quality, expanded discussions on how to obtain optimized dynamic information, and explanations of good and bad imaging techniques, the book covers the topics that are most relevant to performing breast MRI.
MRI has opened up new possibilities in combined morphological and functional imaging, and now there is a book which discusses both aspects together. Two systems which already demonstrate the advantages of MRI are presented. In the cardiovascular system, motion and flow can be imaged so that even flow velocities in the deep vessels of the body can be measured, and turbulences can be identified. In the study of the kidneys, a combination of renally excreted contrast media and imaging provides within seconds insight into glomerular filtration in health and disease. These current possibilities, and their limitations, bring insight into the future potential of MRI.
This book is intended as a text/reference for students, researchers, and professors interested in physical and biomedical applications of Magnetic Resonance Imaging (MRI). Both the theoretical and practical aspects of MRI are emphasized. The book begins with a comprehensive discussion of the Nuclear Magnetic Resonance (NMR) phenomenon based on quantum mechanics and the classical theory of electromagnetism. The first three chapters of this book provide the foundation needed to understand the basic characteristics of MR images, e.g.,image contrast, spatial resolution, signal-to-noise ratio, common image artifacts. Then MRI applications are considered in the following five chapters. Both the theoretical and practical aspects of MRI are emphasized. The book ends with a discussion of instrumentation and the principles of signal detection in MRI. Clear progression from fundamental physical principles of NMR to MRI and its applications Extensive discussion of image acquisition and reconstruction of MRI Discussion of different mechanisms of MR image contrast Mathematical derivation of the signal-to-noise dependence on basic MR imaging parameters as well as field strength In-depth consideration of artifacts in MR images Comprehensive discussion of several techniques used for rapid MR imaging including rapid gradient-echo imaging, echo-planar imaging, fast spin-echo imaging and spiral imaging Qualitative discussion combined with mathematical description of MR techniques for imaging flow
This book presents a comprehensive overview of medical image analysis. Practical in approach, the text is uniquely structured by potential applications. Features: presents learning objectives, exercises and concluding remarks in each chapter, in addition to a glossary of abbreviations; describes a range of common imaging techniques, reconstruction techniques and image artefacts; discusses the archival and transfer of images, including the HL7 and DICOM standards; presents a selection of techniques for the enhancement of contrast and edges, for noise reduction and for edge-preserving smoothing; examines various feature detection and segmentation techniques, together with methods for computing a registration or normalisation transformation; explores object detection, as well as classification based on segment attributes such as shape and appearance; reviews the validation of an analysis method; includes appendices on Markov random field optimization, variational calculus and principal component analysis.
During teaching NMR to students and researchers, we felt the need for a text-book which can cover modern trends in the application of NMR to biological systems. This book covers the entire area of NMR in Biological Sciences (Biomolecules, cells and tissues, animals, plants and drug design). As well as being useful to researchers, this is an excellent book for teaching a course on NMR in Biological Systems.
Dr. Jonathan J. Dutton, a world leader in orbital surgery, presents Radiology of the Orbit and Visual Pathways. This new and unique diagnostic guide offers expert advice on the full spectrum of uses of CT and MRI, the two core methods of radiologic imaging of the orbit. An atlas style approach provides the essential text you need to accurately diagnose over 120 of the more common disorders you’ll come across in your daily routine, and over 1,100 lavish illustrations enhance your visual guidance.

Carcinoma of the urinary bladder is a common (in the USA it is the fifth most common form of cancer in males and tenth most common form of cancer in females) malignan cy and one in which noninvasive staging by imaging plays such an important role. This book presents a complete approach to MR imaging of carcinoma of the urinary bladder from a detailed discussion of the value of MRI in the diagnosis of the urinary bladder to the history of the procedure. The technical discussion of the general principles of MRI including the optimal pulse sequences to be used and factors that influence the quality of images are included in this book. The safety factors are also presented along with contraindications. The application of a double surface coil with the field strength of O.5T provides the fine quality of the illustrations. The atlas of comparative anatomy by MRI on normal volunteers and post-mo'rtem specimens as well as MR images on patients with bladder tumors and post-surgery specimens is unique. The results of the clinical imaging stu dies in patients with carcinoma of the bladder, comparing the relative value of clinical staging, MR, CT and lymphography, are helpful in showing the advantages of MRI.
