This book describes the interaction of living matter with photons, neutrons, charged particles, electrons and ions. The authors are specialists in the field of radiation protection. The book synthesizes many years of experiments with external radiation exposure in the fields of dosimetry and radiation shielding in medical, industrial and research fields. It presents the basic physical concepts including dosimetry and offers a number of tools to be used by students, engineers and technicians to assess the radiological risk and the means to avoid them by calculating the appropriate shields. The theory of radiation interaction in matter is presented together with empirical formulas and abacus. Numerous numerical applications are treated to illustrate the different topics. The state of the art in radiation protection and dosimetry is presented in detail, especially in the field of simulation codes for external exposure to radiation, medical projects and advanced research. Moreover, important data spread in different up to date references are presented in this book. The book deals also with accelerators, X-rays facilities, sealed sources, dosimetry, Monte Carlo simulation and radiation regulation. Each chapter is split in two parts depending on the level of details the readers want to focus on. The first part, accessible to a large public, provides a lot of simple examples to help understanding the physics concepts under radiation external exposure. The second part, called "Additional Information" is not mandatory; it aims on explaining topics more deeply, often using mathematical formulations. The book treats fundamental radiometric and dosimetric quantities to describe the interaction in materials under the aspects of absorbed dose processes in tissues. Definitions and applications on limited and operational radiation protection quantities are given. An important aspect are practical engineering tools in industrial, medical and research domains. Source characterization and shielding design are addressed. Also more "exotic" topics, such as ultra intense laser and new generation accelerators, are treated. The state of the art is presented to help the reader to work with the book in a self-consistent way. The basic knowledge necessary to apply Monte Carlo methods in the field of radiation protection and dosimetry for external radiation exposure is provided. Coverage of topics such as variance reduction, pseudo-random number generation and statistic estimators make the book useful even to experienced Monte Carlo practitioners. Solved problems help the reader to understand the Monte Carlo process. The book is meant to be used by researchers, engineers and medical physicist. It is also valuable to technicians and students.

Volumetric, or three-dimensional, digital imaging now plays a vital role in many areas of research such as medicine and geology. Medical images acquired by tomographic scanners for instance are often given as a stack of cross-sectional image slices. Such images are called ‘volumetric’ because they depict objects in their entire three-dimensional extent rather than just as a projection onto a two-dimensional image plane. Since huge amounts of volumetric data are continually being produced in many places around the world, techniques for their automatic analysis become ever more important. Written by a computer vision specialist, this clear, detailed account of volumetric image analysis techniques provides a practical approach to the field including the following topics:
This text provides a comprehensive review of ERCP and EUS and the clinical conditions for which they are employed. Presented in a case-based format with accompanying videos, it will serve as a valuable practical clinical resource for gastroenterologists with an interest in ERCP and EUS. The text highlights major techniques involved in ERCP, reviews complications and recent data on preventing post-ERCP pancreatitis, and discusses important issues in training in ERCP including use of endoscopic simulators and assessment of competency as emphasized in the new ACGME guidelines. For biliary diseases, new techniques for managing biliary stones, novel technologies for diagnosing indeterminate biliary strictures, and new devices for treating benign and malignant strictures are also highlighted. For pancreatic diseases, advances in minimally invasive endoscopic techniques for pancreatic stones and strictures, and management of the complications of pancreatitis are reviewed. Furthermore, ERCP is not limited by age, pregnancy or history of abdominal surgeries and special considerations particular to these patient populations are also discussed. The EUS chapters review the breadth of equipment available for performing EUS and EUS-FNA, detail the technique of performing EUS-FNA, and explore pertinent issues with training and assessing competency analogous to ERCP training. Valuable insights on the basics of cytopathology relevant to the endosonographer are summarized. The classic indication for EUS of staging luminal cancers is examined in detail while pancreaticobiliary indications are discussed highlighting newer adjunctive technologies including elastography and contrast-enhanced EUS. Although in its infancy, the brave new world of therapeutic EUS is explored with a focus on endoscopic necrosectomy, EUS-guided biliary and pancreatic access as well as the exciting possibilities of EUS-guided radiofrequency ablation and injection of anti-tumor agents. ERCP and EUS: A Case Based Approach will serve as a very useful resource for physicians who perform or refer patients for ERCP and EUS. It provides a concise yet comprehensive summary of the current status of ERCP and EUS that will help guide patient management and stimulate clinical research.

Short compute times are crucial for timely diagnostics in biomedical applications, but lead to a high demand in computing for new and improved imaging techniques. In this book reconfigurable computing with FPGAs is discussed as an alternative to multi-core processing and graphics card accelerators. Instead of adjusting the application to the hardware, FPGAs allow the hardware to also be adjusted to the problem. Acceleration of Biomedical Image Processing with Dataflow on FPGAs covers the transformation of image processing algorithms towards a system of deep pipelines that can be executed with very high parallelism. The transformation process is discussed from initial design decisions to working implementations. Two example applications from stochastic localization microscopy and electron tomography illustrate the approach further. Topics discussed in the book include:* Reconfigurable hardware* Dataflow computing* Image processing* Application acceleration
Functional Electromyography: Provocative Maneuvers in Electrodiagnosis integrates electrophysiology further into the physical examination than ever before. It introduces the use of electrodiagnostic studies to quantify the neurological changes brought about by three provocative maneuvers commonly used in contemporary medicine. This widens the scope of electromyography while sharpening physicians' diagnostic acuity. The book presents nerve conduction velocity (NCV) and H-reflex techniques to identify common conditions that are difficult to diagnose by any other means, often using the needle exam (EMG), MRI or musculoskeletal ultrasound to verify their clinical utility. Functional electromyography successfully diagnoses some cases of thoracic outlet syndrome, nearly all cases of piriformis syndrome, and offers a method for determining whether spinal stenosis or radiculopathy is the main pain generator when both are present in a single patient, even at the same level. This is particularly valuable because the standard conservative and surgical treatments for these two conditions are opposite, in spite of the identical symptom-set they produce. The book carefully describes each technique and persuasively documents their validity in statistical series and individual case presentations. It further guides the attentive electromyographer to adapt these methods to cases beyond those presented in its pages, suggesting a safe and scientific approach to other functional maneuvers of value to the electromyographer, and methods for validating one-time measures that may aid the electromyographer in clinical situations that are neither common nor easily analyzed. Hand drawn illustrations are included alongside text developed by experts in the field. An invaluable resource for physiatrists, neurologists, orthopedic surgeons, specialists in pain management and other providers, Functional Electromyography: Provocative Maneuvers in Electrodiagnosis represents a major contribution to the field of electrodiagnosis.

Modern signal and image acquisition systems used in the field of cardiology acquire, analyze, and store data digitally. Surface electrocardiography, intra-cardiac electrogram recording, echocardiograms, x-ray, magnetic resonance imaging, and computed tomography are among the modalities in the cardiology field where signal processing is applied. Digital signal processing techniques allow us to automate many of the analyses that had previously been done manually with greater precision, accuracy and speed, as well as detect features and patterns in data that may be too subtle to observe by eye. As more cardiologists are becoming more reliant on such technology, a basic understanding of digital signals and the techniques used to extract information from these signals are required.

In the diagnosis and treatment of movement disorders, the use of neuroimaging has expanded widely and has been an exciting, important modality for unlocking the causes of abnormal motor control. With ever improving machinery, data collection techniques and analysis methods, researchers are now being presented with an exponentially increasing amount of data that they must wade through and interpret in the context of existing knowledge about movement disorders. In Neuroimaging in Movement Disorders, the editors have produced a gold-standard resource that brings together an impressive international group of authorities in their respective fields to outline the current state of knowledge. Controversies, such as conflicting findings and methodological limitations, are covered and provide the reader with a comprehensive yet pragmatic understanding of the state of science. The chapters offer both comprehensive reviews of various neuroimaging methods and also more in-depth summaries of the contributions made by neuroimaging in individual movement disorders. Although many of the neuroimaging methods that are discussed have not been routinely used in clinical practice, the authors skillfully provide the reader with adequate detail to understand the requirements for using these methods and in some cases even the starting knowledge to begin local implementation. Neuroimaging in Movement Disorders is an indispensable reference that will be of value to all physicians and researchers involved in the care of patients with movement disorders.
In this book the authors describe their original research on the potential of both standard and high-resolution electroencephalography (EEG) for analyzing brain activity in response to TV advertising. When engineering techniques, neuroscience concepts and marketing stimuli converge in one research field, known as neuromarketing, various theoretical and practical aspects need to be considered. The book introduces and discusses those aspects in detail, while showing several experiments performed by the authors during their attempts to measure both the cognitive activity and emotional involvement of the test subjects. In these experiments, the authors apply simultaneous EEG, galvanic skin response and heart rate monitoring, and show how significant variations of these variables can be associated with attention to, memorization or enjoyment of the presented stimuli. In particular, this book shows the central role of statistical analysis in recovering significant information on the scalp and cortical areas involved, along with variations of activity in the autonomous nervous system. From an economic and marketing perspective, the aim of this work is to promote a better understanding of how mass consumer advertising of (established) brands affects brain systems. From a neuroscience perspective, the broader goal is to provide a better understanding of both the neural mechanisms underlying the impact of affect and cognition on memory, and the neural correlates of choice and decision-making. => Please download the extra material for this book http://extras.springer.com
Regular physical exercise is associated with substantial health benefits. Recent evidence not only holds for cardiovascular effects promoting "physical health", but also for the central nervous system believed to promote "brain health". Moderate physical exercise has been found to improve learning, memory, and attentional processing, with recent research indicating that neuroprotective mechanisms and associated plasticity in brain structure and function also benefit. Physical exercise is also known to induce a range of acute or sustained psychophysiological effects, among these mood elevation, stress reduction, anxiolysis, and hypoalgesia. Today, modern functional neuroimaging techniques afford direct measurement of the acute and chronic relation of physical exercise on the human brain, as well as the correlation of the derived physiological in vivo signals with behavioral outcomes recorded during and after exercise. A wide range of imaging techniques have been applied to human exercise research, ranging from electroencephalography (EEG), magnetoencephalography (MEG), near infrared spectroscopy (NIRS), magnetic resonance imaging (MRI) to positron emission tomography (PET). All of these imaging methods provide distinct information, and they differ considerably in terms of spatial and temporal resolution, availability, cost, and associated risks. However, from a "multimodal imaging" perspective, neuroimaging provides an unprecedented potential to unravel the neurobiology of human exercise, covering a wide spectrum ranging from structural plasticity in gray and white matter, network dynamics, global and regional perfusion, evoked neuronal responses to the quantification of neurotransmitter release. The aim of this book is to provide the current state of the human neuroimaging literature in the emerging field of the neurobiological exercise sciences and to outline future applications and directions of research.

This volume highlights the remarkable new developments in brain imaging, including those that apply magnetic resonance imaging (MRI) and Positron Emission Tomography (PET), that allow us to non invasively study the living human brain in health and in disease. These technological advances have allowed us to obtain new and powerful insights into the structure and function of the healthy brain as it develops across the life cycle, as well as the molecular make up of brain systems and circuits as they develop and change with age. New brain imaging technologies have also given us new insights into the causes of many common brain disorders, including ADHD, schizophrenia, depression and Alzheimer's disease, which collectively affect a large segment of the population. These new insights have major implications for understanding and treating these brain disorders, and are providing clinicians with the first ever set of biomarkers that can be used to guide diagnosis and monitor treatment effects. The advances in brain imaging over the last 20 years, summarized in this volume, represent a major advance in modern biomedical sciences. |
